[ REPORT ] The Robot control using the wireless communication and the serial communication

 Abstract:

 This project outlines the strategy adopted for establishing two kinds of communications; one for wireless communication between a mobile Robot and a remote Base Station, another for serial communication between a remote Base Station and a GUI Application, PC. TekBot is a low cost mobile Robot built by Oregon State University which in its current version requires wired communication. Our aim is to be able to command and control the Robot wirelessly by the GUI Application. This will be a useful addition for NASA’s curriculum development for master’s degree programs.
  The principle task of this project was to program the AVR microcontroller interfaced to a radio packet controller module (operating at a frequency of 433 MHz) which would enable us to wirelessly control the Robot. The communication protocols dealing with transmission and reception of data and wireless control of the TekBot have been successfully implemented. These details are discussed in this report.

1. Introduction

The NASA Robotics Alliance Cadets Program is a far-reaching, innovative project aimed at creating a new highly integrated and interactive college undergraduate level curriculum centered around Robotics and focusing on the content of at least the first two years of Mechanical Engineering, Electrical Engineering and Computer Science. This project is being co-led by Mark Leon, NASA AMES Director of Education and David Schneider of Cornell University and is supported by David Lavery, NASA Program Executive of Planetary and Solar Exploration. The program is being designed to be implemented at a very low start-up cost, and to make this goal obtainable, the program is being developed using low to no cost components from already developed, well-tested and robust engineering testbeds. The Microcontroller board to be used is the Oregon State University TekBots platforms, whose base kit is approximately $100.
