Re: How to increase the accuracy of collision and avoid "crossing"

Position is updated at discrete time steps, so "crossing" may occur when you have high velocity and/or thin objects. With a time-step of 5ms, an object traveling at 10m/s will move by 5cm each time-step. Either have your respondable shape thicker than 5cm or decrease time-step. ODE and Bul...

Re: Changing the maximum acceleration of a robot

The joint is in torque/force mode, with motor enabled, so that's the way to control acceleration.

Re: Vision sensor

The Image plugin uses OpenCV 3 to perform simple operations and drawing on images, and already can read/write to/from vision sensors as well as capture devices (cameras). I think it is a good starting point to extend with further OpenCV functions. To implement new Lua commands remember to edit also ...

Re: Vision sensor

You can write a plugin in C++ providing one or more custom Lua commands, and use whatever image processing algorithm (e.g. OpenCV, TensorFlow, ...) to extract the info you need.

Re: V-REP crashes after selecting SDF import option from Plugins drop down menu

Oh, I think this is related to the fact that V-REP changes the working directory on startup (so relative paths are in fact relative to V-REP directory).

Can you try to use file:// scheme with absolute paths?

I will provide a fix for relative file:// URIs.

A relative URI should be file://meshes/CAD/link_Lf_thigh.stl, not file:///meshes/CAD/link_Lf_thigh.stl

Re: Use of old-style cast

That is correct. In C++ there are only the xxx_cast<...>(...) operators.
