Re: Joint electrical engine mode

Following illustrates how you can set the target velocity and max. force/torque for a force, controlled from your algorithm: function sysCall_jointCallback(inData) local targetVelocity=0.2 -- in rad/sec local maxForce=15 local outData={} outData.velocity=targetVelocity outData.force=maxForce return ...

Re: Programmatically create a non-rigid connection (i.e position but not orientation)

Hello Maxens,

simply use a spherical joint. Something like:

Code: Select all

Terrain --> dummyA
RobotFoot --> sphericalJoint --> dummyB 
or:

Code: Select all

Terrain --> sphericalJoint --> dummyA
RobotFoot --> dummyB 
Cheers

Re: Issue moving platform through UI sliders (IK, no dynamics)

Hello, when you say you were not able to install the Qt UI plugin... did you compile V-REP yourself? If not, then the custom UI plugin should load automatically. Can't you run the demo scene customUI.ttt ? Your problem does not seem to be related to IK. Nor the UI. The problem is that you are trying...

Re: Making wheeled vehicles with kinematics and no dynamics?

Looking at your code, the call to sim.checkProximitySensor on line 40 is probably the slowest of all. Specially if you are calling it for all dummies in the scene, even those that are actually not part of your detection. You can further check timingy via sim.getSystemTimeInMs . To increase speed, sk...

Re: Making wheeled vehicles with kinematics and no dynamics?

Can you post a self-contained scene that illustrates your problem? It will be easier to identify the problem in your script that slows down everything.

Re: Looking for a way to set 2 modes of operation in a single non threaded script

Yes, that is the problem. Can't you use ROS indigo on Ubuntu 16.04?

Re: My Robot doesn´t interact with the floor.

Yes, you will have to clean up everything. Make sure to follow this tutorial for instance.

Re: Joint electrical engine mode

Hello,

your simulated motor can have different velocity or torque profiles, but you'll have to implement this yourself inside of a joint control callback function.

Re: Joint Velocity/Position Control

Why don't you want to use a script? This makes everything much simpler. The second part of my previous reply indicates who you can do things from the remote API. However you then still need to make sure that all commands arrive and are applied at the same time. The normal way of doing would be to fi...
