Re: V-REP on Docker

The solution is

RUN rm libcoppeliaSim.so
RUN mv libcoppeliaSimHeadless.so libcoppeliaSim.so

https://www.coppeliarobotics.com/helpFi ... ndLine.htm

and use ./coppeliaSim.sh -h and it works

Re: Problem to launch Coppelia with ROS2 Interface

The problem solved when you source like this

Code: Select all

source /opt/ros/foxy/setup.bash
not sourcing the local installation folder. It works now.

And for compilation, just remove ros1 and it will work

Alternative to ROS for communication

Hi, Up till now, we used ROS for communication purposes. We think to replace it, but We have no idea what is best. We need: - 2 way communication, which can be initialised by both sides - Well defined messages - Communication should be possible between VREP and external programs (in CPP and Python) ...

Re: B0 Communcation with Coppelia

ROS has concept of actions which service(request and reply) but with feedback especially in long-time taking processes like motion of robot. Does B0(ZeroMQ) has a this concept or have to implement it by ourselves?

Re: B0 Communcation with Coppelia

I have another case as well (most probably the same reason):
if I use in :
C++:
static int i = 0;
Coppelia:
local number=sim.unpackUInt16Table(msg)[1]

I see numbers different than I am sending from the publisher

B0 Communcation with Coppelia

Hello, I tried to use B0Demo Scene and write a publisher using B0 in c++, they communicate but the unpacking in coppelia side is not correct as I send number bigger than zero from c++ B0 publisher but receive at coppelia after unpacking the same number 6.3372196379419e-10. Check the code used below....
