This is the GitHub organization home page for the Representing and Manipulating Deformable Linear Objects (RMDLO) project from the University of Illinois at Urbana-Champaign (UIUC). The project studies robotic manipulation, grasp planning, tactile sensing, segmentation, simulation, and tracking of wires and ropes.
Our growing software stack includes code for controlling two ABB IRB120 6DOF robotic manipulators, the OnRobot 2FG7 gripper, the Intel RealSense d435 camera, the Intel RealSense d405 camera, the Luxonis Oak-D Pro camera, and the DIGIT tactile sensor. For any project-related inquiries or requests, please contact Holly Dinkel [hdinkel2@illinois.edu].
