Simulation fail calling sim.loadScene

Hello, I am trying to load scenes by using the function "sim.loadScene", which i call in a customization script. I actually send a message via ROS to trigger the loading process. The problem is though, that the v-rep closes whenever this function is called. Some of the last lines, that are printed i...

Modelling Environment

Hello, I have a general question about modeling an environment in/for V-Rep. Actually I want to test some algorithms working with camera-data from the simulation, but until now the quality of textures and surface-appearance isn't "realistic" enough. I have started to model obstacles and elements for...

Re: recording Video crashes

Hello again, thanks for your answer! I don't really know what happened, but the error is suddenly gone, although the whole setup of my simulation is the same. Maybe the old-fashioned method of shutting down the computer and restarting it today helped ;) If the error occurs again I'll catch necessary...

recording Video crashes

Hello, recently some problem with the V-REP internal video recorder occurred. Although everything has already worked well, I suddenly get an error "The video compressor failed initializing. Check the console for additional messages." I don't really get any further information what the error comes fr...

Re: Getting reactionforce between wheel and ground

Hello, thanks for the information. I have tested the API function you mentioned with some primitive shapes. Actually the values I receive are correct (like the normal force and the friction force corresponding to the friction coefficient I have set). There is only one thing, though. The shapes have ...

Getting reactionforce between wheel and ground

Dear Community, is there a possibility to get information about forces acting on my vehicles wheel? I know that there is the possibility to read contact forces, but when I'm trying it that way I can only get the normal force, which actually represents the weight distribution of my vehicle. What I wo...

Simulating a differential

Hello, I would like to simulate a car like (all wheel drive) robot. I set the target velocity of the drive shaft (i neglect effects of motor and gearing for simplification). In Order to simulate an appropriate dynamical behavior of the vehicle I need to implement a differential at both axles. I don'...

Re: start and stop Simulation via ROS

Hello, thanks a lot for the useful hints! Actually I didn't know about the functionality of customization scripts, but after looking at the helper model everything is clear to me now. With this useful information the first attempts of my test-platform worked, which is really a big success in my proj...

start and stop Simulation via ROS

Hi everyone, in order to test my path-planning algorithm (which is actually a standalone ROS Node communicating with my robot) I would like to build an automated test-platform . My final goal would be to start the simulation by sending a ros-message (and finally some other information like where an ...
