Re: How to get a lot of data from CoppeliaSim with remote API

Hello, This approach does not work. It does slow down the transmission, so that there is an error:terminate called after throwing an instance of 'zmq::error_t' (python) . So I have to know how to unpack the data outside. If I know sim.unpackFloatTable source code, I can reproduce the function with p...

Re: How to get a lot of data from CoppeliaSim with remote API

Hello, Yes, using simxCallScriptFunction() is a good method, and I can use the function to call sim.unpackFloatTable() to decode data. indeed, I do not have to use python to reproduce the function. But will this way reduce its transmission speed? It's very similar to transferring floating-point numb...

How to get a lot of data from CoppeliaSim with remote API

1. I tried to quickly get a lot of data from Vrep with remoteApi(B0-based remote API, python and matlab). First, using sim.packFloatTable() to pack data; Then, using sim.setStringSignal() to send data to Matlab(or python); it is true that I can get data quickly, but There is no function like sim.unp...

Re: Why can an object break through a table or the ground in vrep

I'm not following. You were talking about objects "breaking through the table". Sorry. I did not describe clearly. I just tried to solve the problem(objects "breaking through the table"), using different method. I changed Physical Energy (Netwon, Vortex, Bullet, ODE). Although those objects are nor...

Re: Why can an object break through a table or the ground in vrep

Does the situation improve if you use a smaller time step? It does not work. when I use Newton, all objects are ok. But Vrep always break, i using B0 Remote API. The error is : ... QObject::~QObject: Timers cannot be stopped from another thread QMutex: destroying locked mutex Error: signal 11: ...

Why can an object break through a table or the ground in vrep

Hi everyone, I made some objects in vrep. I set their convex hull , dynamic and so on. But when a scene starts, some of them can break through the table and the ground and some can not. I checked their properties while theirs are same . I try to change Physical Engine(newton, Bullet and ODE). Yes, t...

Re: After importing a mesh(.obj), it is transparent

Hello, when you say transparent, you mean invisible? Then, it can be that you have one of following situaions: the mesh is extremely large and you cannot see it the mesh is extremely small and you cannot see it the mesh is somehow corrupt. But this situation normally doesn't happen. You can select ...

Re: Robot cannot move along a planning path with IK

Hello,copplia
thank you for your reply.
it works. Vrep is very High-precision. I underestimated its accuracy. Thank you
Cheers
