Vrep performance

Hi, Using 5 vision sensors and rendering them in my scene has really slowed down the vrep simulation. However, V-rep is not fully utilising my CPU(26%) or GPU(40%). I'm using an Intel Core i7 with GTX 680M in SLI. Does Vrep use multi-core,threading or SLI for any of its processing? I've tried doing ...

Re: Custom UI button missing

Hi,

That button was for the OpenGL version. The new Vrep build now supports Qt based custom UI which does not have a menu I believe and everything is done through xml. Have a look here and here.

Best of luck

Dynamic hybrid joints

Hi, I'm simulating a dynamic LBR4 robot arm and controlling it via IK. The problem I'm having is that when dynamic mode is on, the redundant joint is moving by itself for a while before stopping. Looks like some kind of effect of gravity. I've tried playing around with the torque values but it doesn...

Display coordinate frame

Hi, I'd like to be able to persistently display the coordinate frame (red,blue,green arrows) of an object (e.g. joints of a robot arm) during simulation. Is this possible? I've tried using the dummy object but it's not the optimum solution. The arrows are too thin so not really visible unless very c...

Re: Matching Baxter origin in V-rep to Gazebo and Rviz

Thanks for confirming.

So is it possible to load a Baxter model from a URDF file in V-rep in a similar way to Gazebo?

Thanks

Matching Baxter origin in V-rep to Gazebo and Rviz

Hi, I can't seem to match the origin position of the Baxter robot in Vrep to that of the origin used by Gazebo and RViz for ROS. The result being that positions obtainable in one are n't in the other. Is there a way to sync their origin positions. Does Vrep use a different origin? Or is this because...

Getting Baxter joints over ROS

Hi, I'm trying to use the V-rep IK for Baxter to control a real Baxter robot. I'm trying to use the /vrep/simRosGetObjectGroupData service to get the robot joint handles into my python script. To my understanding, this should be returning all the joint handles in the scene. However, it only returns ...

Re: How to add IK to KUKA LBR

For each joint, try checking the hybrid operation option. This fixes the problem for me. I'm not exactly clear on why this is though.

Re: Cameras and views

The camera movement would be controlled through the program based on the movements of the robot so that it always at the same point relative to the robot much like any controlled character is in any 3rd person game. The camera will always be looking at the robot. The tracked object property looks li...

Cameras and views

Hi, I'm looking to implement an "over-the-shoulder" type of camera whose coordinate frame can be used as a reference frame for user input used to control a robot. The camera would be stationary relative to the robot but would be able to freely rotate. I'd appreciate any assistance with thi...
