[misbahsuhail123]

Hello!
I am doing unit5, on giving command
roslaunch fetch_gazebo_demo move_torso.launch
and after that launching trajectory, the fetch robot behaves the way shown in video, is it behaving right? means after some seconds it moves up and down following the motion planing.
thanks

Hello @misbahsuhail123 ,

No, the robot shouldn’t be doing those sudden changes. That is probably because it is receiving multiple data about the joint states of the robot.

What to do for that, i just followed the steps given in the unit. Kindly guide.
Thanks
