Visual teleoperation of an anthropomorphic robotic hand HMU-CSRL 2016-10-10 | This video presents the visual teleoperation of an anthropomorphic robotic hand, mounted on an industrial robotic arm as an end-effector. The teleoperation is solely based on optical data for controlling the motion of the robotic arm-hand system, with 22 degrees of freedom (DoFs). The proposed scheme does not require the user to wear any motion capture glove or other exoskeleton devices. The main task for the system is to imitate user’s hand configurations for grasping objects or performing human gestures. The system consists of the following subsystems: [a] the 16-DoF robot hand “Talos”, developed by the Control Systems & Robotics Laboratory at the Technological Educational Institute of Crete.[b] the Mitsubishi RV-2A 6-DoF robot manipulator, and[c] the “3D Hand Tracking” software for the RGB-D Kinect sensor, developed by the Computational Vision & Robotics Laboratory of the Institute of Computer Science /FORTH. The interaction between the above subsystems is accomplished using a desktop PC with MATLAB installed. The Talos’ hand is used as an end effector of RV-2A and reproduces the movement of the user’s fingers and palm. As a result, the system’s motion imitates that of the user’s hand in near real time, without requiring the user to wear any motion capture gloves or other invasive devices.This research was conducted in the context of a postgraduate thesis, for the M.Sc. in "Advanced Manufacturing Systems, Automation and Robotics", at the Technological Educational Institute of Crete (T.E.I. of Crete).Postgraduate student: E.

Dynamic modeling and experimental analysis of a two-ray undulatory fin robot [IROS-2015] HMU-CSRL 2015-08-13 | Accompanying video for the paper "Dynamic Modeling and Experimental Analysis of a Two-Ray Undulatory Fin Robot" (authors: M. Sfakiotakis, J. Fasoulas, and R. Gliva) which was presented at the2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS-15)Hamburg, Germany (28 Sept. - 2 Oct. 2015)The paper was nominated as a "Best Paper Award" finalist.Abstract: Bio-inspired undulatory fin propulsion holds considerable potential for endowing robotic underwater vehicles with low-speed manoeuvrability and stable station-keeping. Robotic fins typically comprise a number of serially arranged and individually actuated “fin rays”, interconnected by a membrane-like flexible surface. Propulsive forces are generated by the propagation of a traveling wave along the mechanism, via appropriately timed ray oscillations. The present paper describes a dynamic model for an elementary two-ray fin system, analyzed as a standard robot mechanism with additional contributions arising from the elastic deformation of the flexible membrane and from the hydrodynamic forces. The model’s main aspects, particularly with regard to the hydrodynamic effects, are explored via simulation studies, as well as via experiments with a robotic prototype. The developed model can serve a number of purposes towards optimizing the mechanical design, the control strategies, and the propulsive efficacy of robotic undulatory fins.Update: A biomimetic underwater robot that employs a pair of such undulatory fins for propulsion can be seen in youtube.com/watch?v=ytKzx2Xsukk
Swing-up and balancing control of an inverted pendulum mechanism HMU-CSRL 2015-03-31 | This video presents swing-up and balancing control for a pole-on-cart mechanism (inverted pendulum configuration).The swing-up of the system from the stable downward position to the unstable upright position is accomplished by an energy-based controller, which takes into account the finite length of the cart travel along the linear guide.A linear state feedback controller, designed using LQR techniques, is employed for balancing the pole at the unstable upright position.The controllers have been developed as a Simulink block, running under the WinCon real-time extension at a 1kHz rate.The pole-on-cart mechanism was developed by K. Mouratis, as part of his undergraduate final year project (2013). Control Systems Laboratory Electrical Engineering Dept.Technological Educational Institute of Crete Heraklion, Greece.
Propulsion control for a bio-inspired robotic undulatory fin HMU-CSRL 2014-12-25 | This video presents a biomimetic propulsion mechanism, inspired by the flexible undulating fins encountered in certain electric eel species (knifefishes, in particular). The prototype is comprised of eight actively-controlled fin rays (driven by R/C servos), which are interconnected by a flexible silicone membrane. Propulsion is obtained by the propagation of a traveling wave along the fin, obtained through appropriately coordinated motions of the rays. The results from a series of detailed parametric investigations (sample runs are shown in this video) reveal several important findings regarding the effect of the undulatory wave kinematics on the propulsion speed and efficiency. Based on these findings, two alternative strategies for propulsion control of the robotic fin have been developed. In the first one, the speed is varied through changes in the undulation amplitude (Amplitude Modulation Velocity Control scheme), while the second one involves simultaneous adjustment of the undulation frequency and number of waves (Frequency/Phase Modulation Velocity Control scheme), in a manner which enables attaining a specified desired swimming speed with optimum efficiency.The video presents experiments demonstrating closed-loop position control of the prototype, based on these two strategies.Additional details can be found in the following publication:M. Sfakiotakis, J. Fasoulas, M.M. Kavoussanos, and M. Arapis, “Experimental investigation and propulsion control for a bio-inspired robotic undulatory fin,” Robotica, vol. 33, no. 5, pp. 1062–1084, 2015.
Arduino-based embedded control of a Pendubot mechanism HMU-CSRL 2014-10-20 | This video presents an embedded controller developed for a laboratory pendubot unit. The pendubot is a mechatronic device used in control engineering education and for research in nonlinear control and robotics. This device is an underactuated two-link planar robot with an actuator at the shoulder but no actuator at the elbow. The developed embedded control unit is based on the 8-bit Arduino Mega 2560 microcontroller platform, with a custom-designed i/o shield. The latter integrates electronic circuitry for interfacing the microcontroller to the two rotary incremental encoders of the mechanism, as well as for generating the analog voltage signal, provided as reference input to the current mode servo amplifier unit that is used to drive the dc motor actuating the shoulder joint. The firmware implements state feedback controllers for balancing the pendubot at various unstable equilibria. Data regarding the state of the system are streamed in real time over a serial link during operation of the controller. 2014 Final year project by Kourtikakis Manolis and Kapellakis ManolisProject supervisor: Dr. M.

Development of a 16-dof robot hand HMU-CSRL 2014-04-10 | Design, Development and Control of the Talo's Robotic HandDr. J. Fasoulas, J. Konstandoudakis, N. KritsotakisThe needs for robots have recently changed from factory automation to human friendly robot systems that interact with the real world. Such robotic systems must be able to grasp and manipulate objects like humans. The development of dexterous robotic hands is essential and a challenging topic among Robotics Engineers.In our Automation & Robotics Lab, at the Mechanical Engineering Department of the Technological Educational Institute of Crete, we designed and developed a robotic hand that has real life grasping capabilities. The robot hand has 16 degrees of freedom, is made of ABS material using a 3D printer, and employs 16 r/c servos (driven by an SSC-32 controller) as actuators for the revolute joints of the fingers. The robot hand can be controlled by using special MATLAB instructions that are based in the forward and inverse kinematic analysis of the system.The Robot Hand shown in the video was developed as a final year project by J.

Development and control of an inverted pendulum system HMU-CSRL 2013-10-07 | This video presents the development of a pole-on-cart system, along with the design and implementation of appropriate controllers for balancing the pole in the upright unstable position (inverted pendulum configuration).The pole-on-cart system was created around a linear slide mechanism salvaged from an old dot matrix printer. Additional parts were designed in CAD software, and fabricated in ABSplus material using a 3D printer. A 48V DC motor, powered by a servo-amplifier in current mode, imparts the actuating forces to the cart through a cable drive transmission. The position of the cart along the track is calculated from the angular position of the motor's output shaft, which is measured using an optical encoder. A second optical encoder, mounted on the cart, is used to measure the angle of the pole. The pole balancing controllers were designed using LQR techniques, and run in real time under WinCon in Simulink.2013 Final year project by Mouratis Kyriakos (Kiriakos)Project supervisor: Dr. M.

Robotic Stewart Platform HMU-CSRL 2013-07-19 | A Stewart platform is a type of parallel robot that incorporates six prismatic actuators. These actuators are mounted in pairs to the mechanism's base, crossing over to three mounting points on a top plate. Objects placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move. These correspond to the three linear movements x, y, z (lateral, longitudinal and vertical), and the three rotations pitch, roll, & yaw. The Stewart platform design is extensively used in flight simulation, particularly in the so-called full flight simulator for which all 6 degrees of freedom are required. In this role, the payload is a replica cockpit and a visual display system, normally of several channels, for showing the outside-world visual scene to the aircraft crew that are being trained.The robotic Stewart platform shown in the video was developed as a final year project. It has been fabricated in ABSplus material using a 3D printer, and employs 6 r/c servos (driven by an SSC-32 controller) as actuators for the prismatic joints. A program written in Matlab is used to calculate the platform's inverse kinematics and send via RS-232 the appropriate commands to the SSC-32, in order to achieve the desired position/orientation for the object mounted on the top plate.2013 Final year project by Kalantzis S.
