The software in this project was used to create a maze-solving rover using a Rover 5 robot platform, an Atmel ATMega328 chip, and a QTR line sensor. The software is written in C, and can be compiled using the avr-gcc compiler.
Required Parts:
- Polulu QTR-8RC Reflectance Sensor Array
- Rover 5 robotics platform
- Atmel ATMega328 microcontroller
- LD33V 3.3V voltage regulator
- 2 x H-Bridge motor drivers
- 10uF electrolytic capacitor
Data Connections:
- QTR-8RC - PD0-PD1 (left sensors), PD7-PD8 (right sensors)
- Motor Drivers - PC3-PC4 (right motors), PC5-PC6 (left motors)
Logic Board Specifications:
- 9v (6 x AA @ 1.5v) battery pack
- MCU VCC is 3.3v regulated
- H-Bridge VIN is 9v unregulated
- PSU is an LD33V with a 10uF capacitor between VCC and GND
