This document summarizes several projects completed by Chun Ho Wong between 2014-2015 including calibrating sensors, developing a walking robot called "The Spider", building models of cruise control and adaptive cruise control systems using Arduinos, and creating an autonomous "Rocket Turtle" that could track and retrieve colored objects using a myRIO microprocessor and LabVIEW software. CAD drawings and prototypes were created for each project.

1. Project Introduction
Chun Ho Wong

2. Content
• Calibration of Different Sensors (2014 Fall)
• The Spider (2014 Fall)
• Experiment on Cruise Control & Adaptive Cruise Control Systems
(2015 Spring)
• Rocket Turtle (2015 Spring)

3. Calibration of Different Sensors (2014 Fall)
• Calibration of an Infrared Distance Sensor
• Calibration of an Accelerometer
• Calibration Based on Limited Recourses
PXI-1042Q Chassis

4. Calibration of an Infrared Distance Sensor
• Data Sheet was provided
• Infrared Distance Sensor was placed on the top of the tube
• Using three different setup to calibrate

5. Calibration of an Accelerometer
• Only knew the output signal was frequency
• Had to develop a calibration method
• Developed a relationship between gravity and the output signals

6. Testing Apparatus

7. The Spider (2014 Fall)
• A walking mechanism
• Focusing on mechanical parts
• No microprocessor involved (No programming algorithm involved!)

8. CAD Drawing(Using SolidWorks)

9. Exploded View

10. Prototype

11. Experiment on Cruise Control & Adaptive
Cruise Control Systems
• Built two vehicle models
• Involved Arduino Uno microprocessors
• Developed PID controller algorithm

12. CAD Drawing(Using SolidWorks)

13. Prototype

14. Rocket Turtle (2015 Spring)
• Involve a NI-myRIO microprocessor (LabVIEW)
• Three wheels
• Two sprocket Chains – One controlled the direction. Another
controlled the forward and backward motion
• Two Modes:
Mode I – Manually control by a Xbox One controller
Mode II – Automatically capture a tossed color object

15. Software Logic (Mode II)
Track the position
of the tossed
color object
Predict the
landing position
Calculate the
angular deviation
between the
object and the
camera
Calculate the
position
difference
between between
the object and the
camera
Send signals to
servo motor and
two DC motors
Rocket Turtle
begins to move to
the object
