Visual Servoing Platform  version 3.2.0 under development (2018-08-16)
movePioneer.cpp

example showing how to connect and send direct basic motion commands to a Pioneer mobile robot.

WARNING: this program does no sensing or avoiding of obstacles, the robot WILL collide with any objects in the way! Make sure the robot has about 2-3 meters of free space around it before starting the program.

This program will work either with the MobileSim simulator or on a real robot's onboard computer. (Or use -remoteHost to connect to a wireless ethernet-serial bridge.)
