02: Simple Visual Servoing | V-Rep Tutorial

Step-by-step vision-based control with V-Rep. This video shows the step-by-step implementation of a pan-tilt camera that tracks a moving object using the Virtual Robotics Experimentation Platform (V-REP) simulator, which can be downloaded for free at http://www.coppeliarobotics.com/ . The detection is achieved using colour-based object detection and the tracking uses a simple image based visual servoing control scheme. The contents are covered include: 00:00 - Introduction 01:02 - Path Creation 03:13 - Creation of an object that moves along a path 06:30 - Modelling a pan-tilt camera base 09:49 - Vision sensor addition and property modification 15:47 - Colour-based object detection with vision sensor filters 22:00 - Adding a script to the vision sensor 23:21 - Debug console,simAuxiliaryConsolePrint, and Object Handles 27:16 - Reading vision sensor data 32:56 - Programming a visual servoing control scheme 36:43 - Reducing tracking error 37:30 - Changing camera output and graphing joint velocities
