Re: Ackermann steering

Hello,

Have a look at the attached model. It implements Ackermann steering programmatically. Mechanical implementation is also possible, but is not as precise.
The attached model will be included from next V-REP release on (V3.0.2) (check the "models/examples" folder)

Cheers

Re: Dynamic simulation is slow and unstable

Hi, Not sure whether this is your problem, but you probably are not using pure shapes. A physics engine can simulate collision response between 3 types of shapes : 1) Random shapes (non-convex, polygon soups, etc.) 2) Convex shapes 3) pure shapes (primitive shapes: cuboids, spheres or cylinders. Som...

Re: Dynamic simulation is wobbly/shaky

Hi, You very probably have mal-adjusted the inertias and/or masses of your dynamic objects. The physics engines require that you don't have too large differences in masses or inertias in a same mechanism. For instance, having a shape with mass 1kg attached via a joint to another shape with mass 1g, ...

Re: URDF importer plugin

Hi, You are right. We corrected a few bugs in that plugin, namely following: - Scaling was not taken into account - Sometimes the plugin would hang when importing object names that contained forbidden chars for V-REP - There was a mix-up in rotation multiplication order The corrected version will be...

Re: My plugin is not loaded

Hello, This is probably due to the fact that under MacOSX, the application is packaged (i.e. in a bundle). You need to copy the plugin inside of the bundle, where the other plugins are located. Typically: "./vrep.app/Contents/MacOS". That's where the client application is also located. Che...

Re: Can we import our Solidworks robot designs into V-REP?

Hello, Yes you can do it, but you will have to export your design to some V-REP compatible format first. V-REP currently supports: DXF 3DS (Windows only) OBJ STL COLLADA URDF V-REP could also be customized via a plugin or add-on to import other formats. Refer to the COLLADA or URDF plugin project fi...

Re: Rendering seems to be very slow

Hello, Maybe your graphic card is simply too old (several years old) and can't handle it. But I suspect it might be linked with another problem: This sometimes happens with some graphic cards (typically Nvidia), and more often on Linux systems. There can be several reasons and several solutions. Mos...

Re: Cannot compile V-REP. Items seems to be missing

Did you follow the compilation instructions from the user manual? http://www.coppeliarobotics.com/helpFiles/en/compilingVrep.htm Basically you should first install V-REP PRO or V-REP PRO EDU. That installation package contains a programming folder that is needed during compilation (i.e. contains som...

Re: getting v-rep to run

Hello, Did you copy-and-paste the created library into the original V-REP PRO EDU folder? Make sure to copy all created libv_rep.so.* files into that directory. You may have to recompile the client application (vrep). At the same time, if libv_rep.so itself cannot find what it needs, the client appl...
