Atmel ATmega16 Based AVR Robot Controller

The project was built around the powerful Atmel ATmega16 processor to create an AVR robot controller that will be used as the base controller for a Mini-Sumo robot project.

The processor used for this controller has 16kb of memory running at 8MHz for an 8-MIP processing speed. To allow doubling of the CPU speed, a 16MHz crystal is included while the memory is doubled by the available update. A variety of free or commercial tools such as BASCOM basic compiler, Atmel Assembler/Simulator, GNU C compiler, and Code Vision C, can be used to program the board along with inexpensive in-circuit debugging tools.

In using the Atmel AT90S8535 AVR microprocessor, the speed is also doubled and the I/O capabilities are expanded. The processor contains serial port, dual H-bridge motor driver, connectors for two additional R/C servo output or encoder inputs, and connectors for five analog or digital inputs, to provide complete solution for small robots.

To make a serial interface cable that can be used to connect the ARC board to the PC, the small PCB, DB9 connector, and 3’ gray cable are used. The programmer uses a male DB25 connector.
