I change the time step by code: p.setTimeStep(time_step)
Then call p.stepSimulation() in loop code.
I got the velocity of a joint, the value is vary to the different time step setting.
The difference of peak velocity is large.
What is the problem? My choice of time step is not property?

Re: how to change joint position
Thanks! I have read the example code by code. But I can not find out the code which define the location of joint.
