Re: Chain of joints with PID position control

Hello, Did you play with the example model in models/examples ? Also, make sure to read this topic . When you have a chain, the problem is always more complex because all elements influence each other. Before going any further, you could try to write your own low-level joint controller, and implemen...

Hello Geerten, We mentioned this change in the very first point of the new release: here . We cannot possibly enter into details for every changes we make, since that would require to write a book everytime ;) When mentionning specific things that other people do not know (i.e. your simulation probl...

Re: Spring force

Here is Hook's law: F=k*x where F is the force of a spring, k its constant, and x its displacement (or stretch/compression) In V-REP when using the setting previously mentioned: F=ctrl*maxForce where ctrl is the control, and maxforce the maximum force indicated for that joint. For ctrl we have: ctrl...

Re: How does the Remote Control Server work?

We will do our best for the next release... but I cannot guarantee it. But it has a high priority compared to other things!

Re: Dynamic properties back to default after update

Hello Geerten, This is very probably linked to your previous problem. Could you confirm that setting the parameters to what you had in the past solved the problem you mentioned in another post? What actually happened is following: In version 3.0.1 there was a small bug that would affect some shapes:...

Re: Spring force

Hello Geerten, a joint that is in force/torque mode, and has the PID controll enabled, together with the "regulate torque/force" item, will behave like a spring (also damped if desired). In above described mode, the positional error (e) of the joint will be used to calculate a force on tha...

Re: How does the Remote Control Server work?

Hello Poseidonius, If you can get Python to load a new instance of the remote API library, then you should not have any problem. Maybe you just need to restart a new Pyrthon interpreter at each time. And as Eric said, there will soon be a new version of the remote API capable of handling several con...

Re: Shortcuts

Hello,

Actually it goes round. However the focus is taken by the "rotation" dialog, so the main window cannot process the key anymore. Just click once in the main window, then you can go round again. We'll have a look to alter this behaviour, since it is true that it is annoying.

Re: Car Simulation

Hello,

if you download the last V-REP (V3.0.2) then you will find an Ackerman steering car model (in models/examples/simple Ackermann steering)
