Not crashing here (CoppeliaSim 4.0.0rev1 on macOS). But I don't have the vortex engine, so I changed that to Bullet 2.78. Does it make a difference?

Re: CoppeliaSim crashes when using the distance calculation module

Does this happen with the scene scenes/minimumDistanceCalculationDemo.ttt?

Re: Streaming video from vision sensor/camera of Vrep to a remote device

However consider this: If you are transmitting uncompressed images, UDP is probably a bad idea anyway, especially if anything wireless is involved. A 640x480 image with RGBA color amounts to 1.2M data. Assuming a frame size of 1500 bytes per packet, you have to transmit about 820 packets per image. ...

Re: Streaming video from vision sensor/camera of Vrep to a remote device

I think the latency is caused by the TCP transport.

ROS also supports UDP transport (see the ros::TransportHints class). With a small change in the ROS plugin you can enable that.

Re: trying c++ hello world program on the youbot model in Vrep

To program V-REP in C++ you have two options:
  • write a plugin (code runs in the same process)
  • use the remote API (code runs in another process)

Re: trying c++ hello world program on the youbot model in Vrep

No, the robot model can be used with the V-REP API (e.g. setting joint target positions, moving ik target, etc...).
If you want to simulate the YouBot's C++ API you would need to write that layer to interface with the V-REP API.

Re: Streaming video from vision sensor/camera of Vrep to a remote device

If possible, using ROS, ROS2 or BlueZero can simplify things a little bit, as you won't have to deal with sockets but with a higher level abstraction.

Re: Accessing to the shape triangle minimizing distance in the distance calculation module

It is not available in the CoppeliaSim regular API.

But it is available in the coppeliaGeometricRoutines library, so you should be able to use that in a CoppeliaSim plugin.
