We Drove Our Lunar Rover Analogue For The First Time! Charlie Hanner 2023-07-28 | We hooked up a motor driver to one of the wheels and did some driving with our rover! Then we put the rover on a cart, and pushed it over to our other building for the electronics integration phase (using the one powered wheel as the traction power rather than pushing!). We also did a photoshoot for a proposal putting TRAVELS on VERTEX and using the crane to pose the two rovers in various phases of deboarding.

Testing UMD’s Robotic Lunar Rover Prototype in the Desert with JPL Charlie Hanner 2022-12-27 | This wheel-on-limb rover known as TRAVELS (Terrapin Rover Allows for Versatile Exploration of the Lunar Surface) was built in the University of Maryland's Space Systems Laboratory for NASA's 2022 BIG Idea challenge. This video is a summary of our experiences at the competition, from arrival and robot assembly through the desert testing and wrapping up with our tour of NASA's Jet Propulsion Laboratory. The rover was fabricated almost entirely from 3D printed components with commercial actuators paired with planetary gear sets and custom fabricated aluminum driveshafts. The abbreviated timeline of only 8 months for this project and a university-level research budget drove the system to this form as an efficient use of money and accessibility to researchers with little to no previous robotics experience.More information and our final paper for the project can be found at: charliehanner.com/travels

Lunar Rover Rollout Charlie Hanner 2022-09-12 | This is the first rollout of the SSL's new Earth-analogue lunar rover! @nicolasbolatto and I have worked for two years on the design, development, and manufacturing of the project hardware, and the rollout finally happened on Friday, September 9th. Months of welding, grinding, milling, hand filing, and beneficial friendly disputes have resulted in a rover we are incredibly proud of. This video also shows the initial verification runs of the suspension systems, driving each swing arm through 75% of it's total actuation range and at slower speeds (hence the sped-up video segments). This produces the chassis movements in pitch and yaw, which will eventually be used as an active control mechanism to guarantee stability on high slopes. There is still a lot of work ahead, but this was the first gigantic hurdle to cross. Onto the next improvements. Thanks to @oversteermedia for the final editing pass!

Tormach 1100MX Y Axis Issue Demo Charlie Hanner 2021-05-05 | Demonstration of backlash issue in the Tormach 1100MX shipped to us.
Loud - 1100MX Tormach Y-Axis Howl Charlie Hanner 2021-05-05 | This shows how we discovered the issue in our Tormach 1100MX. The squeal in the cutting of this circle when the tool aligns with the Y axis of the machine is suspected to be caused by a 0.003” slop in the axis from factory. The distinctive screeching sound you can hear is caused by the machine bed (and therefore the attached part) vibrating back and forth rapidly with an amplitude we believe to be the ~0.003”. The motion here is supposed to be on the level of ten-thousandths of an inch. As the part and table vibrates, it makes irregular contact with the spinning end mill, resulting in rough surface finished, reduced tool life, and unacceptable finished part tolerances. We’ve been trying over the last few months to remedy, thinking it was an issue in our tooling or work holding, or any other factor. But after running indicator tests we found the issue lies in the connection between the Y-axis ballnut and the cast machine bed. Notice the X-axis does not product this same issue, and after indicating shows to be well within the machine tolerance. The z axis additionally has not shown any issues. The issue appears to be contained to the Y-axis. The part being machined is a 7075 6” round billet in its first of 4 operations. This one is specifically for work-holding and indicating strategies in the later stages of the part.
Driving a Robot From Home? Charlie Hanner 2021-01-22 | This test was our first successful completion of two main objectives:1) Operate our satellite servicing manipulator from a remote location in real time2) Perform non-simulation testing of rotation about a predetermined fixed point While my coworker Nicolas and I were the in-person team for this test, Joe was communicating with us via video chat and controlled the robot solely based off a single camera angle and his software simulations. Lots of changes, improvements, and upgrades are well on the way for Ranger with many more tests planned in the coming months including the next step in this experimental direction: Underwater micro-gravity simulation with an inertial satellite mockup. The yellow strap surrounding the arm later in the video acted as a safety in the event of unforeseen manipulator issues, and the structural piece placed in RANGER's parallel jaw mechanism near the end is a long extrusion plastic representation of an ISS handrail.

Ranger Plate Milling Charlie Hanner 2019-08-05 | This is the milling process for Ranger's interstitial plates on its positioning leg, and all parts shown are untouched after coming off the machine. They'll undergo sanding and anodizing before installation, and once assembled I'll post a video about where these fit and more about their purpose. After over a mile of machine path, a 3.38 lb plate with an isogrid is milled from a 21 lb, 12x12x1.5 piece of rectangular stock (that's 83.9% material removed!) over the course of ~10 hours of machine time (not including setups and tool changes)(Music provided by bensound.com)
Rocket sequence testing of payload! Charlie Hanner 2019-06-25 | Here we can see both arms functioning on the rocket with the flight time clock in view!
RockSat-X Payload Integration Charlie Hanner 2019-06-25 | Here is a video we took at check-in that shows the functionality of the robots on the University of Maryland’s RockSat-X Payload. You can see in this video everything from pre-launch to launch to experiment microgravity phase to stowage, and unfortunately while recording this video the farther of the two arms had a software crash mid experiment, however successfully rebooted and began its experiment again. We are happy to report this did not happen during any of the other testing throughout our integration week, and the mass ejection systems on the end of the arm both survived vibrational testing loads with full functionality of the robot. Overall a great week and the next month can be spent refining the robots further for anticipated flight on August 12th.
