2007 GSW Robot Soccer Game and Map Explorer Project

Brief Introduction:

This is the first time a robot soccer game is organized at Georgia Southwestern State University. Hardware platform is based on the Lego mindstorms Nxt set. The software controllers of both teams are developed based on NXT# library.The controller uses Bluetooth to communicate with the NXT brick of our robot. We added key mappings to the sample programs provided by NXT# and successfully improved the efficiency of the software controller.

Great Map Explorer

Brief Introduction:
 

Robot map explorer is a very challenging project. We are required to take advantage of the ultrasound sensor and plot the whole 2-D territory map of a building with all lights out. The complexity of this project comes in multiple folds. First of all, we had the trouble of rotating ultrasound sonar -- we could not even finish one full circle of the rotation because the USB cable was entangled with the robot chassis during rotation. The second problem we had is the accuracy of sonar. With the assistance of Dr. Fu, we managed to build a complete suite of software simulator and controller which can not only control the robot via Bluetooth wireless but also simulate the exploration of our robot in a virtual environment.
