WebIf you have an arm with 7 joints, and a trajectory with 100 points, then the size of joint_names should be 7 and the size of points should be 100. For each point, the elements positions, velocities, and accelerations will be of size 7. The idea is that for point p and joint j, joint_names[j] corresponds to points[p].positions[j] WebSep 9, 2024 · Joint space trajectory script unclear. I have a script provided by The MathWorks Inc. that makes a robot end-effector follow both a task space and a joint space trajectory through several waypoints. These trajectories are then plotted in the same figure (shown below). For some reason the joint space trajectory makes these huge loops.
