Re: how can I auto start a add-on script through cmd

You have to name the script simAddOnScript_xxxx.lua (note the underscore instead of the dash)

Re: how to connect the learning algorithm written by Julia to V-Rep ?

Also, quoting from https://www.infoworld.com/article/3241107/julia-vs-python-which-is-best-for-data-science.html: Julia can call Python, C, and Fortran libraries. Julia can interface directly with external libraries written in C and Fortran. It’s also possible to interface with Python code by way of...

Re: how to connect the learning algorithm written by Julia to V-Rep ?

You are right: there is no remote API interface for the Julia programming language.

But there is an interface to ROS for Julia, so you can use that to connect Julia to V-REP.

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.
