Re: simExtOMPL_setValidStateSamplerCallback not working as intended
Forgot to mention this, but also have put in print statements into the sampler calls, and it appears that the functions are not being called (none of the print statements appear in the console). Code for the sampler functions ground_sampler=function() print("ground_sampler called") min_x, ...

Re: simExtOMPL_setValidStateSamplerCallback not working as intended
Ok, have started changed the child script in start_config to use simExtOMPL_printTaskInfo and it seems like something is wrong with the callback and callbackNear variables. I have a script that calls OMPL 3d path planning with a custom sampler (to sampler all states where z=ground_height). The code ...

simExtOMPL_setValidStateSamplerCallback not working as intended
I believe the function simExtOMPL_setValidStateSamplerCallback is not working as intended. I think the callback functions (args 2 and 3) are not being set and you can put in invalid function names and still get a return code of 1 instead of the failure code of 0. Below is how I've tested this and ca...

Re: Unstable robot at simulation start
Could you be more specific on what you mean by falling down? If by falling down you mean falling through the simulation floor, it's might be because the body is not respondable (in the dynamic properties of an object). If by falling down you mean the robot is falling over, it might be because the bo...

VREP OMPL car path finding
Hi, I am trying to use VREP's OMPL plugin to have a car find a path over a 3d hill. It seems like using the 3d state space is lacking in that I need the state space expansions to have the car be along the ground. To fix this it seems like you need to use simExtOMPL_setValidStateSamplerCallback. Are ...

Example of ROS RGBD data publisher
From the change log for V-REP V3.0.5 (October 27th 2013), Added a ROS publisher for vision sensor depth data as RGBD point cloud, courtesy of Cedric Pradalier. Has anybody used this publisher? I can't seem to find any examples of this and the Vrep API doesn't seem to have it (for vision sensors can ...

Extending Vrep OMPL API
Have been looking at VREP's OMPL API and was wondering how to extend it. What I want is to put in a custom cost function for my robot. At the moment this doesn't seem to be supported in the API (just checks for collisions as far as I can tell). Was wondering how to add a cost function or more genera...
