If I give a movep
command to the robot that includes the XYZ location of the TCP, then the rotation part of the target pose is ignored. Reproduction is easy, here’s a script:
def unnamed():
set_tcp(p[-0.04014,2.0E-4,0.09948,1.2092,-1.2092,-1.2092])
set_gravity([0.0, 0.0, 9.82])
set_target_payload(2.000000, [0.016, -0.014, 0.101], [0.004887, 0.004887, 0.004887, 0.0, 0.0, 0.0])
Waypoint_1_p=p[-.300, -.250, .350, .0, 0.0, .0]
Waypoint_2_p=p[-.300, -.250, .350, .0, 1.0, .0] # <- Only differs in rotation
movep(Waypoint_1_p, a=0.5, v=0.1)
movep(Waypoint_2_p, a=0.5, v=0.1)
end
With this script, I would expect that the robot would rotate around the TCP, but it doesn’t move at all.
I found this forum post that I think is probably the same problem, but I see that despite the UR support person verifying the behaviour, there was no resolution.
