Re: How to move a robot using regular API?

Hello, if your robot is dynamically enabled, i.e. has a mass, will fall, etc., then you can't instantaneously change its position. It would be like teleportation in real life. You need to drive to robot towards the position you wish, via a controller that actuates the wheels of the robot. Of course,...

Re: Computed Torque Controller

Hello, use something like following instead: for i in range(100): sim.simxPauseCommunication(clientID, True) for j in range(6): sim.simxSetJointTargetVelocity(clientID, joint_handles[j], 10000000000, sim.simx_opmode_oneshot); sim.simxSetJointForce(clientID, joint_handles[j], taumat[i][j], sim.simx_o...

Re: Simulating Ratchet Mechanism

Hello, I would put that inside of a joint callback function, inside of a child script attached to that joint. And don't check the torque applied to it, but the movement direction instead. Something like: function sysCall_init() jointHandle=sim.getObjectHandle('joint') lastPos=sim.getJointPosition(jo...

Re: Deformable Terrain in CoppeliaSim? (Vortex Engine)

Hello Samuel,

CoppeliaSim unfortunately doesn't implement that functionality from the Vortex engine. So this is currently not possible to have a deformable terrain.

Cheers

Re: headless bug ?

Hello Lyz,

no, that is not normal. Can you describe in which situation exactly? Or do you have a minimalistic scene that illustrates this?

Cheers

Re: How to get the exact position of a shape using regular API?

Hello, not sure what the blue line represents... or the red and green line in that picture. The reference frame of a shape is always located in the middle of that shape. If you know the extent of the shape, then you can figure out other coordinates on your shape. You can always use a ray-type proxim...

Re: Undergraduate Kilobot Course UoA

You can't directly open them, since they are too old. You will have to download an intermediate V-REP version (e.g. from 3 or 4 years ago, e.g. version 3.3.2) open the scene, save it. Then you should be able to open it with CoppeliaSim. We can do the conversion for you, just contact us via email . C...

Re: Robot don't follow the path at begin

The problem is as I explained previously: you drive your robot exclusively via IK. By having all 6 constraints enabled (position and orientation). Eventually, some joints will be close to a joint limit and IK won't work anymore (remember, IK will try to move in a straight line in Cartesian space), s...

Re: Future of Remote API

Hello,

both will continue to coexist. They both have their advantages.
The B0-based remote API doesn't directly support C, but that would be easy to achieve.
