AVR Robot Controller 1.1

06/20/2008 Category: AVR, Digital, Project

The AVR robot controller (ARC 1.1) was designed as the base controller for a high school Mini-Sumo robot project. The controller is built around the powerful Atmel ATMEGA16 processor with 16kb of memory running at 8 MHz for an 8 mip processing speed (contrast this with a 20 MHz PIC which has a 3-4 mip equivalent speed or an 8mhz HC11 with about 1/2 mip equivalent speed). A 16 MHz crystal is included to allow doubling of the CPU speed. Pin compatible upgrades are available that double the memory.
