Smooth floor

Dear Coppelia I command the robot to a straight line. Even though it goes straight I graph the angular velocity, which is generally zero and it makes some spikes. I observed this happens when the robot wheels cross the lines of the floor (they act as gaps and they add disturbances to the model). I w...

Graph set into radians per second

Hi Coppelia I am using a Graph with function Object: angular velocity (), when I plot it in XY curve it shows the velocity in degrees per second, how can I measure in rads per second? Morevover I use Graph with function Object:absolute velocity() in order to graph at XY curve the linear velocity of ...

simulation Dynamics explained better

Hi I have a problem with vrep. I try to simulate a differential robot that drives to a specific point of the surface. The algorithm I use is very common and it is described in this book at page 94 on book at this link I have here https://www.dropbox.com/s/mr7euyfyhatc9yz/%5BIntelligent%20Robotics%20...

Simulation Dynamics

Hi! I want to simulate a robot that has to get to a target position by a control algorithm with feedback. I simulated it in Matlab and it works perfectly. Now I want to verify by vrep but it fails to get to the target position. I believe this happens because of the physics engine like friction, iner...

Re: Show variables values at the console

Thanks actually I was trying these but it did not work and then I figured out it was a problem in the libraries

Hello,

you can also drag the model Models/other/signal monitor.ttm into the scene: you will be able to read the state of the various signals.

Cheers

I found this model but I did not understand how it is used to view the channels

Show variables values at the console

Hi I would like to ask you with which function can I show the value of a variable at the console. I already know the sim.AddstatusBar but it only works for messages with string character So the child script of the robot is for example function sysCall_actuation() quat=sim.getObjectQuaternion(MainBod...
