224 FINAL PROJECT-WIRELESS CONTROL OF A BOE-BOT

• Tom Cohlmia-Scott Moffat-Ashley Nidiffer-Eric Yim

2
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.

3
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

4
Calibration
Servo Motors

• Run servo motors at 750 and zero the motion

Gyroscope

• 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

5
Angular Velocity vs. Voltage

• Calculate the linear equations of the line

6
Wireless

• Learned Bluetooth software
• Sent and Received text wirelessly

7
Programing

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

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
