2021-05-20 07:08:42 -0500 | marked best answer | Which ROS controller to achieve 'teachmode'? Hi I'm using ROS Kinetic to control the Elfin 6 DOF robot arm, and am looking into the options to achieve 'teachmode' with ROS. With 'teachmode' I mean this , also known as: freedrive, backdrive, compliance, zero-force. Which ROS controller?It's not clear to me which controller is suitable (or that I need to write a controller from scratch myself), I couldn't find any code examples how teachmode can be achieved. I found the following control options, but it's not clear how to use them for teachmode, and which one is suited: Implementationthe robot I use (Elfin) has torque sensors in each joint, and I can read the effort of all joints on /joint_states. It also comes with different hardwareinterfaces I started by implementing a gravity compensation controller in gazebo,based on this. This is implemented, but needs commands to move. do I need to use the joint effort to calculate joint position/effort/velocity commands? I hope someone can clearify the different ros controllers, and how to achieve teachmode. If there are any relevant topics/github please let me know :). |
