sorry i forgot to tell, the error I get is:

QMutex: destroying locked mutex.
I've seen that message a number of times, but I don't use the URDF plugin, so I guess that message is not related to your problem.

Re: Understanding of "UR5withRG2Grasping.ttt"

It's the angle of the joints.
You can move joints manually or via IK, then you can read the angle in degrees in the main view, when the object info is expanded.

Re: Photorealistic rendering capability

There are external renderers such as OpenGL3 and POV-RAY which produces very high quality rendering:

Have a look at the rendererDemo.ttt example scene.

Or have a look at how they did it with V-REP VR Toolbox.

Re: Understanding of "UR5withRG2Grasping.ttt"

dropConfigN is the targetPos argument (that is: the desired target positions of the joints) passed to sim.rmlMoveToJointPositions

Re: simROS.getTime() returns incoherent values

That probably is the culprit (mismatch between executable/library and ROS distribution).

Re: How can I show the relative coordinate between two Dummy

sim.getObjectPosition: the second argument indicates the handle of another object relative to which reference frame we want the position.

Re: simROS.getTime() returns incoherent values

To my knowledge there are no binary releases of v_repExtRosInterface.

You have to compile it from source using the ROS environment installed on your machine.

Re: simROS.getTime() returns incoherent values

The implementation of simROS.getTime() is to simply return the value of ros::Time::now().toSec().

Did you compile Lua with single precision floats?

Re: pressure on gripper

V-REP does rigid body simulation. Since a strain gauge is a deformable body, in principle you cannot simulate that. However, you can use a joint to act as a spring (see this post , this other post , and the example in models/examples/spring-damper ) and measure the displacement caused by a force/tor...
