Re: The setting of friction in the Vortex engine

Well, you will have to try. With Vortex you have much more options. So, for instance, to change the friction, simply change Friction coefficient under Linear primary axis . The Linear secondary axis's fricition is the same by default as the linear primary axis, but you can change that (then you woul...

Re: Object slipping down while being lifted

Hello, unfortunately that gripper is very difficult to correctly simulate. Grippers in general are a tricky subject. With that particular gripper, the mechanism is modelled as the real gripper, which is the problem. Normally, one would model a gripper in a simplified manner, in order to have a stabl...

Re: Check Remote API Communication with MATLAB in Lua

Hello, I would make it even simpler: on the Matlab side, simply set the float signal to the desired thrust. On the V-REP side, read the thrust signal. If the signal does not exist, then the connection was not established yet. If the signal exists, read it and set it to a specific value (e.g. negativ...

Re: Transfering camera and gyro data from V-REP to the MATLAB via RemoteAPI

A Camera in V-REP doesn't not have a specific resolution: it can display in a large sub-view, and in a small sub-view too. At the same time, you cannot perform any image processing on it, nor retrieve the image. On the other hand, a vision sensor has a specific resolution and mode of operation. You ...

Hello,

they used to have the linux version as download also available. Can you check with them directly?

Re: Output

Hello, are you stopping and restarting the simulation, or is the robot having a different behaviour the second/third/etc. time it turns around a specific corner. The second situation would be quite normal, since you would cumulate the whole simulation history. In the first case, then, unless you are...

Re: Setting individual joint position in IK mode

Oh, if you have dynamics turned on, this is a different story and not that easy.
What exactly is your problem with your current situation? Maybe you are searching in the wrong direction.
Best would be to post a simplified version of your scene so that we can have a look at it.

Re: Inverse Kinematic: what are the parameters that influence the joint velocities?

You have several possibilities to do that. The simplest would be to have the IK group in explicit handling. Then, each time you receive an initial manipulator configuration from your external application, set all joints to the specified values (with sim.setJointPosition ), then call sim.handleIkGrou...

Hello,

try by modifying the value of doNotShowCrashRecoveryMessage in file system/usrset.txt
