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)
Calibration of Different Sensors (2014 Fall)
• Calibration of an Infrared Distance Sensor
• Calibration of an Accelerometer
• Calibration Based on Limited RecoursesPXI-1042Q Chassis
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
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
Testing Apparatus
The Spider (2014 Fall)
• A walking mechanism
• Focusing on mechanical parts
• No microprocessor involved (No programming algorithm involved!)
CAD Drawing(Using SolidWorks)
Exploded View
Prototype
Experiment on Cruise Control & Adaptive Cruise Control Systems
• Built two vehicle models
• Involved Arduino Uno microprocessors
• Developed PID controller algorithm
CAD Drawing(Using SolidWorks)
Prototype
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 controllerMode II – Automatically capture a tossed color object
Software Logic (Mode II)
Track the position of the tossed color
objectPredict the
landing position
Calculate the angular deviation between the object and the cameraCalculate 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
