Max number of items in a scene and performance.

Hello Coppelia, I am planning to build a complex environment in VREP with several objects in the scene, for simulate robotic navigation and colaborative robotics in an heterogeneous environment. Apart from my personalizes robots which are going to be controlled by myself by an external API, I have p...

Draw over a surface

Hello, I am interested on being able to simulate "draw" over a surface, as it is presented at the beginning of your promotional video of 2014 (https://www.youtube.com/watch?v=gBYqOBdIcaY). What I want is something like that: simulate a robot draw over a surface and detect it by a vision sensor. I've...

Re: Segfault on start-up in Ubuntu 18.04

Hello,

I've found today the same issue, but installing what fabro and fferri posted here looks like it works for me. The user interface show sometimes strange behaviors, but the simulation seems to work properly.

Thanks for posting a solution.

Regards!

Re: Strange behaviour among PCs and in the same PC

Hello Coppelia,

We do not have the real time mode enable. Our configurations settings are those that came from default. I supposse that if the computers are different, a simple program as I have post (without any type of calculation) would work similar in both PC in non-synchronous mode.

Regards!

Re: Strange behaviour among PCs and in the same PC

Hello, What It happen is: I'm using a Python external API and I'm working wiht Python functions. The pseudocode I'm using is the following: for n in range (0, 4): returnCode, posicion_inicial = vrep.simxGetObjectPosition(clientID, carcasaHandler, -1, vrep.simx_opmode_buffer) targetVelocity = [-vel_i...

Strange behaviour among PCs and in the same PC

Hello, A colleage and me are working on a project and we found a strange behaviour on VREP. We are running a mobile robot, we use revolute joints as motors. We control our mobile robot by the external Python API. We use the "simxSetJointTargetVelocity" function for moving the robot. In this context,...

Hello, I've worked with VREP many times, and I still can do it. But now a colleague has started to use the VREP too and we've found a problem. We share a folder which we work on the same program. It consist of an VREP scene, and a Python project. We use the external Python API for controlling our ro...

Python external API question

Hello, After working a little with the VREP, I have some issues I'd like to clarify. I'am working in a scene in synchronous mode. I think I spend too much time in a start o stop command. For testing this, I've written a simple program using the bubbleRobscene.ttt for testing the time between the sta...

Re: python and vrep

Hello wpc,

For starting with python and VREP communication, I recommend you this video tutorial:
https://www.youtube.com/watch?v=SQont-mTnfM

For me was very useful in a starting point.

Re: Problem with Stop command and reset scene

Hello again, "when you stop a simulation, make sure to also stop streaming all data." Many thanks, that was very useful to me. Stopping the streaming data as it is mentioned here: http://www.forum.coppeliarobotics.com/viewtopic.php?f=5&t=1577&hilit=return+3&start=10 works for a "motor reset" and it ...
