04: Python Robot Simulation with V-Rep | V-rep Tutorial

Step-by-step robot simulation with Python and V-Rep with obstacle avoidance of a Pioneer 3DX differential drive robot. This video shows you how to connect Python with V-rep and how to write a simple obstacle avoidance script in python that randomly drives a Pioneer P3DX around a scene, while avoiding obstacles. It's no Google self-driving car, but it gets the job done. Within the tutorial I will go over how to set up the V-rep Python connection, retrieve object handles, control robot acutators, read proximity sensors, and retrieve and display images in python. The video will provide you with a rough script that can get your Python V-rep project started. I will also show you how to use the list of remote API Python functions located at: http://www.coppeliarobotics.com/helpFiles/en/remoteApiFunctionsPython.htm The final python script and the corresponding v-rep scene file can be downloaded at: http://www.edisondev.net/VREP/04PythonTutorial The python(x,y) distribution can be downloaded for free at: https://code.google.com/p/pythonxy/wiki/Downloads The Virtual Robotics Experimentation Platform (V-REP) simulator, can be downloaded for free at: http://www.coppeliarobotics.com/ .
