224 FINAL PROJECT- WIRELESS CONTROL OF A BOE-BOT Tom Cohlmia-Scott Moffat-Ashley Nidiffer-Eric Yim

Objective  Our goal in this project was to use wireless technology to control a robot along a given path.  To accomplish this we will integrate the Basic stamp and LabView programs.

Parts  Assembled Boe-Bot, Parallax Robotic Kit #28132  Blue Tooth Wireless Adapter, DBT120  Wireless Card, eb500  Gyroscope, ADXRS150EB Hardware Challenges  Basic Stamp Chip malfunctioned  Wireless card communication failure  ADC Chip was not provided

Calibration  Run servo motors at 750 and zero the motion  Run the robot in a circle, record time and angular distance  Use LabView to record the Gyroscope output  Graph the angular velocities vs. output voltage Gyroscope Servo Motors

Angular Velocity vs. Voltage  Calculate the linear equations of the line

Wireless  Learned Bluetooth software  Sent and Received text wirelessly

Programing We used 2 programming languages in this project: LabView and Basic Stamp. LabView Basic Stamp

Gyroscope  Calibration of servo motors  Calibration of Gyroscope Servo Motor

LabView  Used to Record Gyroscope Calibration Data  Configure LabView to connect to Bluetooth  Write a LabView program to control Boe- Bot

Demonstration

Conclusion Limits:  Lack of ADC chip  Speed of communication of the wireless  Accuracy of LabView angle calibration Next Steps:  Install and wire an ADC chip  Integrate the gyroscope into the LabView program  Integrate feedback into program
