The goal of our project is to have all of the sensors fully operational. We will build a small-scale demo robot to display some of the capabilities. Design Considerations Power Motors We will use the PWM features of the microcontroller to control an H-bridge power transistor configuration. The H-bridge will be controlling a higher power supply for the motors. We will use the analog inputs of the microcontroller.
Tentative sensors are reflectance sensors, phototransistors, and potentiometers.
We will use the digital inputs of the microcontroller. Digital Outputs We will use the digital outputs on the microcontroller. A HEX display will be used for debugging and a directional pin is used for each motor. We will use the serial port RS232C to connect to the PC for debugging and downloading.
