How to connect directly to a PS4 gamepad with LEGO MINDSTORMS Robot Inventor Antons Mindstorms 2022-04-12 | In this video, I'm showing how to connect a PS4 gamepad to a MINDSTORMS Robot Inventor robot. It also works with LEGO SPIKE Prime. Out of the box, the Robot Inventor kit can connect to a gamepad. But only in the laggy streaming mode and only with a desktop or laptop computer in between. Also the official LEGO setup does not support Python! This setup fixes all that by using a small LMS-ESP32 board in between. That board pairs with any Bluetooth Classic gamepad - like the PS4, Microsoft Xbox One, Nintendo Switch, and most of their clones. The LMS-ESP32 board then sends the results over UART to your MINDSTORMS robot. You can pick and process about 30 gamepad inputs per second. This makes for mighty snappy remote control!💬 Please like and ask any questions you have in the comments!--- Chapters ---00:00:00 PS4 gamepad to Robot Inventor direct Connection00:00:28 Introduction of the hardware setup: LMS-ESP3200:02:20 Pairing the PS4 gamepad with the MINDSTORMS Robot Inventor model00:02:49 Lagless connection of the gamepad to the 51515 Robot00:04:33 Demo of PS4 direct connection to Mecanum Wheel Robot Inventor Car--- Links ---Blog post with the step-by-step tutorial👉 antonsmindstorms.com/2022/03/22/python-ps4-gamepad-connection-robot-inventor-and-spike-prime-hubGet the LMS-ESP32 board here:👉 antonsmindstorms.com/product/wifi-python-esp32-board-for-mindstormsCode repository and example projects: 👉 github.com/antonvh/mpy-robot-toolsGet the T-Shirt 👕 here: 👉 https://shop.spreadshirt.nl/antons-mindstorms/Support 🙏 my work: 👉 patreon.com/antonsmindstormsFor complete building instructions 📄 and in-depth articles go to:👉 antonsmindstorms.com

MINDSTORMS Robot Inventor Mecanum Wheels drives in EVERY Direction Antons Mindstorms 2022-01-11 | Watch how I connected four Mecanum wheels to the four motors of the LEGO MINDSTORMS Robot Inventor 51515 kit. The result is an amazing car that can drive in every direction and turn around its axis. Here’s how to assemble and program the Mecanum wheels.💬 Please like and ask any questions you have in the comments!Mecanum wheels are a lot like omni-wheels. The omniwheels are also known as rotocasters or holonomic wheels. An Omniwheel has no lateral grip and would go everywhere. But Mecanum wheels are different. Unlike rotocasters, the Mecanum wheels have diagonally oriented rolls. If you push a wheel like that sideways, it starts to rotate! Some people call this type of wheel the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon. Ilon came up with the concept while working with the Swedish company Mecanum AB.I used these wheels:2x right side: dfrobot.com/product-2271.html?tracking=KuVJyhg7ViWvTzwnTpVkQztSs49q2bHS4iXsF0r8KiKJVoz20ppvOx4FHfVbONxc2x left side: dfrobot.com/product-2270.html?tracking=KuVJyhg7ViWvTzwnTpVkQztSs49q2bHS4iXsF0r8KiKJVoz20ppvOx4FHfVbONxcCode STL 3D Print file and detailed description: 👉 antonsmindstorms.com/2022/01/07/building-a-lego-robot-inventor-51515-mecanum-wheel-omnidirectional-car🎶 Music: Robogroove by Wander Vanhoucke--- Chapters ---00:00:00 Mecanum wheel robot Inventor Omnidirectional Car00:00:20 Introduction and overview of 51515 model00:00:57 What Mecanum wheels can do00:01:42 Remote control options: SPIKE, Android app, or another hub00:02:30 Mounting the Mecanum wheels with 3D printed hub00:04:10 Orienting the MECANUM wheels: left and right!00:04:58 Omniwheels vs Mecanum wheels00:07:21 Pure LEGO Mecanum wheels00:09:42 Programming with word blocks or Scratch00:11:05 Programming the Mecanum wheels with Python00:26:03 Python programmed Mecanum-wheel car with Robot Inventor Driving--- Links ---Get the T-Shirt 👕 here: 👉 https://shop.spreadshirt.nl/antons-mindstorms/Support 🙏 my work: 👉 patreon.com/antonsmindstormsFor complete building instructions 📄 and in-depth articles go to:👉 antonsmindstorms.com

Ultra-fast SPIKE wall follower robot with laser distance sensor in word blocks. Antons Mindstorms 2021-05-25 | Don't worry, this laser can't damage your eyes! Check out this video to see how much better it performs in a wall follower robot. The sensor is extremely fast and accurate, much more so than the included LEGO distance sensor. Unlike the ultrasonic sensor, it works under large angles and can spot soft objects. But - this is the cool thing - just like the LEGO sensor you can use word blocks to program it!The sensor contains a 940nm Vertical-cavity surface-emitting laser (VCEL). It uses Single Photon Avalanche Diodes (SPADs) to catch reflected light and calculates the distance using light speed! Sounds like Star Trek? It's real!ERROR CORRECTION: In the movie, I tell you that tweaking the sensor settings can make it report longer distances than just 1200mm. This is only partly true. The specific model I'm using doesn't range much further than that. However, the LPF2 protocol allows for sensors with a longer range than 200cm.

How to control speed and distance with complex walking robots by bending time. Antons Mindstorms 2021-03-22 | Learn how to make Ladybug roam around the room without hitting the wall. You will also learn how to control the distance to the wall. The challenge I had with many robots is that there is no central 'speed' parameter if multiple motors have to coordinate to create walking movement. I resolved this by synchronizing all motors with time and then bending time, forward and backward, to control the total motion.

Did you want to animate a real robot like a 3D model? I did. And I built a keyframe system in Python to help me do it. That system was the key to make GELO do consistent hand-plants. Keyframes were also essential for my Tars project. The SPIKE Prime Ladybug uses keyframes too in its Python program.In my previous article, I showed how to run multiple motors in sync by defining their time functions. Time functions are a good start, but they have limited flexibility. Sometimes you need more control over timing. Take the walking animation for Tars. First, Tars has to drop his shoulders and swing back slightly. In the next 200ms, Tars has to swing his body forward while lifting the shoulders. And so on. To time and define every motor position, I used keyframes. Get the complete program and building instructions for Tars in the digital downloads section.Keyframes like Pixar for your Robot Inventor creationsAnimators who make movies use keyframes for this. Keyframes are certain positions where the movie characters have to be at a specific point in time. Those keyframes can be seconds apart, and computers calculate all the frames in-between for a smooth movement. Movies can have up to 60 frames per second, so it's a good thing we have computers. Walt Disney had to draw every frame manually. Pixar uses keyframes and computers to render their fantastic movies. A keyframe for a MINDSTORMS Motor in PythonI don't want to have to define every motor position 20 times per second for my robots. I want to define just a few moments in time and their corresponding motor positions. Then I want my programming code to do all the calculations in-between. This combination of timing and position is what I call a keyframe. Interpolation of Keyframes in PythonNext comes the challenge of calculating everything in between the keyframes. The calculation of a frame between two other frames is called interpolation. You don't have to worry about the precise calculation because my code does that for you. What is more interesting now is how to use that The principle is the same as with the time functions for synchronizing a mechanism. You create a function that returns a motor angle if you feed it a moment in time. Only this time, the parameters for creating that function are keyframes. In Python, it looks like this:Edge handling of the interpolated keyframesWhat if you define keyframes and time runs beyond your last keyframe moment? Or it runs before the first keyframe? In that case, we have an edge situation. I have built three ways of handling the edges in my interpolation code: constant edges, wrapping, and wrapping with accumulation. The simplest of these three is constant edges. This means the function returns the angle of the keyframe at the closest edge. Here's a graph of the result. I never actually used it, but it might be handy one day.The second type of edge handling is wrapping. This means the function copies and infinitely repeats the set of keyframes, both forward and backward in time. It is what I use for Tars.The third type of edge handling is wrapping with accumulation. This is the same as plain wrapping, except that I add a constant value after each wrapping. Keyframe transformation convenience for walking robotsApart from handling edges, I also wanted to conveniently manipulate the keyframes. When to motors are mounted in a mirrored fashion, the interpolation function allows you to invert the keyframe values. The interpolation system can also create a time offset. This is handy for Gelo's front and hind legs: they have a time difference of half the loop time. With one set of keyframes, inversions, and offsets, you can now configure GELO's complete walking movement.

Synchronized motors are essential when you make robots dance or walk. Legs and arms need to move in unison for the robot to advance. I have abstracted the process to control motor positions based on a single input parameter. This method makes it real simple for you to make all kinds of robots walk and move.You can see in the video how I linked all motor movements to a single number. If I change that number with the external motor, you see the animation unfold. I use this method in the SPIKE Prime Ladybug, 51515 Tars, the Swing Monkey, and LEGO MINDSTORMS Gelo. One point in time, one position for SPIKE MotorsThe basic idea of the system is that every single point in time corresponds with a motor position. Based on that idea, I searched for mathematical functions that calculate this relation. I wanted functions that would take time as an input and give me a motor position in degrees as an output. Then I could scale this up to as many motors as the LEGO MINDSTORMS hub can support. If every motor has a time-function, I can steer each motor to its desired position at any point in time.The Mechanism() class to control all LEGO MINDSTORMS/SPIKE motorsTo control all motors with functions, I wrote a Python Mechanism class. It takes two lists as its input: a list of motors and a list of functions. Once you have set up the Mechanism, all you have to do is feed it the time. The class will then set all motor powers according to their distance from the desired position at that point in time. Make sure to either keep updating motor powers in a loop or stop them completely. If you stop updating them, they will keep running at the last calculated motor power.How to think of LEGO motor functionsAs motors rotate clockwise, their position keeps 'increasing.' After one revolution, a motor position is 360; after two revolutions, it is 720. Outwardly, it might look like it is in the same position again, but the motor has continued counting on the inside. The difference between the inside counter and outside position makes motor functions a bit hard in the beginning. To illustrate this, I have made some graphs with typical motor functions.The linear motor function in LEGO PythonThe legs of Gelo and the outer legs of the Ladybug have a linear function. Linear means the motors run at a constant rate. Every unit of time, they rotate a unit of rotation. In my Gelo python program, the motors rotate 360 degrees per second. That is 360º/milisecond or 0.36º/ms. In this graph, I have plotted all Gelo motor functions. The slope of the line is a measure of the speed of the motor. Steeper is faster. If the line goes up, the motor runs forward. If the line goes down, it runs backward. The intersection with the Y-axis shows how far the motors are apart. In this graph, you can see that motors A and C run backward. You can also see that motors A and B are 180 degrees apart. The same goes for motors C and D. The Mechanism class 'pulls' motors to the right position at every point in time. If they are ahead, they will slow down or even reverse. If they are behind, they will increase the motor power.The wave function for dancing LEGO robots
How to make three motors move in Sync with MINDSTORMS and SPIKE Antons Mindstorms 2021-01-07 | Please like and ask any questions you have in the comments!Get the T-Shirt on: https://shop.spreadshirt.nl/antons-mindstorms/Support my work on: patreon.com/antonsmindstormsFor complete building instructions and in-depth articles go to:antonsmindstorms.comHow to run two motors at the same time (motor synchronization)In this video, I'll explain how you can run motors to different positions simultaneously. Running these motors at the same time is difficult with LEGO MINDSTORMS or SPIKE Prime because the move-to-position block finishes the complete movement before going to the next block. To show you how this works, I'll use this Ladybug model. The Ladybug model needs to move one set of legs backward while moving another set forward. Furthermore, this model needs to tilt to the correct side every time it moves its propulsion legs.You can follow this video with three motors connected to your LEGO hub. For the full experience, you can download the building instructions for this SPIKE Prime Ladybug on my website. This tutorial works for both LEGO MINDSTORMS and SPIKE Prime. I'm going to use the SPIKE app. Why do we need synchronization?Why is this tutorial important? Let me show you. If we do not run motors at the same time, we can still make the ladybug walk. We can program the robot to run each motor in turn. What you then get is this movement. It works, but it looks clunky. It's robotic in a bad way. Wouldn't it be much smoother if the legs moved at the same time?Option 1The first option for running motors at the same time is selecting multiple motors in the blue block. Let's see how that works. The problem here is that you can choose only one target per set of motors. Multiple motors will not work for our ladybug because one set of legs has to run forward while the other runs backward. I could cheat by moving this pin here. But then I will not be able to turn on the spot anymore.Option 2Our next option is to broadcast a message. If we broadcast, we can start several stacks at the same time. Every motor in every stack will start together at the moment of the broadcast. Let's have a look at that.Option 3Our third option is to use the pink movement block. LEGO provided this block to drive straight with a robot. To drive straight, the robot wheels need to move at precisely the same speed. They should also stop together and start together. We can use that behavior for other purposes than driving. Let me show you how that works with the ladybug.Finally, we want to tilt left and right, based on the position of the movement legs. Here's how that works.If you have learned a thing or two about programming in this video, it is a great idea to hit the subscribe button. I'm making new MINDSTORMS and SPIKE tutorials all the time.

I compared EV3 to Robot Inventor in a previous video. Here, we'll look at SPIKE Prime vs. 51515 Robot Inventor. The comparison is interesting because both sets have very similar hardware, and you can get them for about the same price. I've seen both boxes retail at a price between EUR 340 and EUR 380.LEGO targeted SPIKE Prime at educators. You can't even get it in official LEGO shops and most retail stores. The only official way to get it is through a LEGO Education supplier, although some online stores sell it to everyone. The idea behind SPIKE Prime is to give teachers a tool for exploring robotics with their class. It is colorful, easy to use, and full of 1-hour activities. The models are small and straightforward. SPIKE Prime aims to teach about concepts like programming, entrepreneurship, robotics, and the environment. In my opinion, SPIKE appeals to ages 8-12. There are exceptions: some adults do crazy stuff like making a trapeze artist swing 360's. LEGO MINDSTORMS 51515 Robot Inventor is a so-called 'retail' set. With that set, LEGO aims for kids who want to have fun and be creative. There is little to no educational content in the app. It's mostly fun activities. The models are much larger, so the building fun lasts longer. It's interesting how the MINDSTORMS brand has left the classroom. Seymour Papert - who originally coined the term - was creating material for school kids. He found out that kids will learn and explore if you create inspiring worlds around math, language, or programming. Exploring these worlds gave kids Mindstorms. Adults enjoy their Mindstorms too. Some take up meditation, while others just buy a box of LEGO MINDSTORMS. I'd say Robot Inventor appeals to kids in the age range of 10 to 100 years old.The LEGO SPIKE box vs. the LEGO 51515 boxAs an educator's tool, SPIKE Prime has a solid plastic educator's sorting box. LEGO designed SPIKE Prime to be assembled and taken apart daily. The boxes stack neatly for storage at school. The lid snaps on to prevent the loss of bricks.To give you more plastic to build with, LEGO Robot Inventor comes in a cheaper cardboard box. It still is a better box than the average LEGO box because it has a lid and you can reclose it. Most other LEGO boxes tear open from the side and end up in the paper bin. It does not feature sorting trays, however, or a large format print of the part list. This style of box is practical at home, but it is a nightmare in the classroom.LEGO 51515 electronics vs. SPIKE Prime electronicsThe electronics inside both sets have a lot of commonalities. They both have the new 6-port hub, albeit in a different color. Both have the new medium motor, light sensor, and ultrasonic sensor. This is where the similarities end.SPIKE Prime features two particular electronic parts over MINDSTORMS Robot InventorSPIKE Prime features a Force Sensor and the Large Motor. The force sensor is an upgrade from the EV3 touch sensor because - as the name suggests - it can sense the gradual force applied. The EV3 touch sensor could only sense pressed or not pressed. Force sensing is excellent in classrooms where you learn about springs, newtons, mass, and weight. When building cool robots, there is less use for such a sensor. The Large Motor has a larger torque than the medium motor, but also a more inconvenient form factor. Even though it has more pin holes, I find it more complex to build with. So for I never had a lack of torque on the medium motors. Maybe they are useful in large robot arms?LEGO MINDSTORMS Robot Inventor has better robot electronicsWhat Robot Inventor lacks in variety, it makes up for in quantity. There are no less than four medium motors in the set. They come in a practical shade of grey that is easy to combine with other colors. When I build robots, I will always choose an extra degree of movement over a force sensor. It is the more practical set in the daily life of a Technic robot builder.

It has many improvements over EV3. Find out here what the differences are between EV3 and the new 51515 Robot Inventor set. I guess people will be calling this LEGO set 'teal MINDSTORMS' or 'MINDSTORMS 5' or 'MINDSTORMS 515', which is short for the set code. Part of my review is to try and build a little car without any instructions. This experiment will give us a feel for the increased speed of building with the new set. Let's have a look!Like all LEGO boxes, the set number, set name, and suggested age is here in the top left. It is a 10+ set. EV3 had no age marking on the box. My experience is that the age group is the same. I have organized fun First Lego League build sessions using EV3 with 10-year-old kids. The graphics are very different from LEGO technic and the previous MINDSTORMS. The black and bright colors give the set a bit of an 80's retro-cool look. Sizewise, the box is the same as your good old EV3 box. The packaging shows that it's compatible with Mac, PC, Android, and iOS. LEGO really went out of their way to develop and support all these platforms. As you've seen in all of the previews, the new MINDSTORMS hub is basically a green SPIKE Prime hub. This means we get a built-in gyro and accelerometer. With the internal six-axis inertial motion unit, you can sense the orientation of the hub. It can also detect taps. You can also read out its rotational speed over 3 axes. Especially for walking robots, this will be great. I remember struggling a lot to get my blue dragon walking because everything was so heavy. Unlike the EV3 hub, this hub has a built-in battery! Yay! No more tedious charging of AA cells. It also has pinholes on ALL sides. Not just bottom, left, and right. Compared to EV3, these motors are way smaller, lighter, and more comfortable to build with. I guess they will have less torque, but this won't be a problem since your robots will be much lighter. And you get no less than FOUR of them. This is really awesome. I remember that with EV3, one of the first things I bought was another motor.You will recognize the sensors from the SPIKE Prime set. There is no force sensor, but we do get an ultrasonic and a color sensor. I don't expect I'll ever miss the force sensor. Like SPIKE, these new motors have an internal absolute positioning system. With EV3, I used the force sensor mostly for calibrating motor positions. If you want to make your robot interactive with buttons, remember that you can use a motor as a button. You can also tap the hub because there's an accelerometer inside. I remember running out of 5 x 7 frames often when building with EV3. This was so frustrating that I bought the bucket wheel excavator. The reason? There was a HUGE amount of frames in that set. It seems that LEGO has listened to people like me. They have included way more 5 x7 frames. Not only that, that set also has the new 7 x 11 frames and the 11 x 15 frames. I like frames because you can build so quickly with them. They are pretty rigid and take parts from almost all sides.This set has Ninjago missile launchers. I guess proper robots should have guns? This part can do nothing but shoot. Maybe the missiles could function as a pair of legs for a walking robot.This box includes no less than six wheels! Mars rovers are now within your reach.

Robot Swing Monkey going 360 with official SPIKE Prime app Python Antons Mindstorms 2020-08-23 | Here's a video to show that you can paste any python code inside a Python project in the SPIKE Prime app. You can download the code here: antonsmindstorms.com/product/spike-prime-swing-monkey-building-instructions-pdf-downloadThe original code I developed for the Swing Monkey in VS Code works here too. I also made a version of the code with the official API LEGO Python motor commands. When this Monkey does 360 turns, you need a real fast control loop to keep it going. The performance of the SPIKE Prime hardware is adequate for this if you run it with Python.
