Extra Sensors
Before lab 3, teams will need to pre-select and research a sensor allowing the robot to turn left, right, around and spin in place. These will vary in price, difficulty and effectiveness. These are just a few known options:
- IR Reflective Sensor
- IR sensor
- plus Interrupt driven intersection detection with Finite State Machine (FSM) interrupt service routine (ISR)
- Sparkfun I2C modules
- Compass
- Gyro with Matlab option
- IMU
- plus filtering techniques
- Rotary also called shaft encoders
- Conductive – Quadrature
- Conductive – Pulse with Interrupts
- Optical (slit and reflective)
- Magnetic (on-axis and off-axis)
- Capacitive
- Resistive
- plus encoding techniques
- Ultrasonic Sensor for turns and tracking
