Task Description

Create cartesian control package for arm controller; taking the arm’s ros2_control published values and transforming them using inverse kinematics to X,Y,Z co-ordinates such that we can send/publish desired X,Y,Z co-ordinates to the arm for it to move to via a ROS2 action.

Task Breakdown

Read into Aidan Keaveny’s ROS1 repo linked below; find out if it’s feasible to port it from ROS1 directly
If porting Aidan Keaveny’s repo is not feasible, look into FZI Research Center’s package (see documentation links)
Git branch off of https://github.com/uwrobotics/uwrt_mars_rover/tree/user/keyonjerome/%231/arm-control-bringup

Prerequisites

  • Working arm URDF; our current arm URDF is done and useable, but very low fidelity. Consider using http://wiki.ros.org/sw_urdf_exporter to convert the arm’s SolidWorks assembly to a URDF that may make the simulation easier. Not required.
