Re: Torque mode control with Python in CoppeliaSim 4.3

Thank you for your response. Your suggested solution did the trick. However, I noticed another strange behavior. The torque read by function sim.getJointForce is always the opposite of that set by sim.setJointTargetForce (same magnitude but opposite sign).

Yes, the same behavior with Lua.

Torque mode control with Python in CoppeliaSim 4.3

I am trying to control UR5 robot in torque mode with a Python main script in CoppeliaSim 4.3. I dragged the UR5 robot into the main scene, changed all 6 joints from position to force mode, and replaced the (default) main Lua script with a Python code. Then I tried to play with the torque passed to t...

UI widget in "ABB IRB 140.ttm"

In the older versions of CoppelianSim/V-REP, "ABB IRB 140.ttm" used to have a nice user interface to directly simulate the forward and inverse kinematics of the robot. I can't find that user interface in the latest version. Is there a way I can get it back? Thanks.

API to spawn robots

I am working on the control of a fleet of robots (20+). Instead of manually dragging and dropping them onto the scene, one by one, is there a way to do that in the code?

Re: Mass-Spring-Damper system

I don't think that solution has the effect I want. I tried it with different spring constants, but the mass didn't exhibit any oscillations.

Mass-Spring-Damper system

I have been trying to use CoppeliaSim to build a classical Mass-Spring-Damper system. For that, I have two rectangular slabs (cuboids), one on top of the other (the lower being static while the upper is dynamic). Between the two, I am supposed to insert a spring and a damper, but I do not know how t...
