Robot Arms in ROS
INTRODUCTION
This section introduces concepts in planning and control of robot arms. The presentation approach is ground-up. At the lowest level, joint controllers are specified, whether position controlled, velocity controlled or force controlled. The next higher layer of abstraction is specification and execution of joint-space trajectories, which include coordination of joint displacements at planned arrival times. Through consideration of forward and inverse kinematics, one can compute joint-space solutions that are appropriate for performing specific tasks. To construct a viable joint-space trajectory, one must consider Cartesian motion plans and choose among inverse kinematic options to construct corresponding feasible ...
