### V-REP Path planing

I want to know which path planning algorithm is used in path planning module, and is it possible to change the back-end algorithm used to compute the path.

Moreover Any video tutorial about collision detection module

A RRT algorithm is used.

If you want to implement a different path planning algorithm, best would be to take the approach to create a plugin that exports new Lua commands for path planning: this would be the easiest, and the cleanest option.

It is RRT connect, or a variation of it (depending on the type of path planning).

What I suggested with the plugin is following:
Once that is done, you can communicate with your plugin via the custom lua functions you have registered. So your code could look like:

Code: Select all

taskHandle=simExt_createPlanningTask()
calculatedPath=simExt_findPath(taskHandle,{joint1Start,joint2Start,...},{joint1Goal,joint2Goal,...})
