Circuit Lake

This is cool robot project by Nicola. He build Self-Balancing Robot which can stand without fall. He use Arduino Diecimila as main processor. For the sensord the robot project use Sparkfun IMU Combo Board - 2 DOF - ADXL203/ADXRS401.

This is a combo Gyro/2-axis-acelerometer. Of the many combinations avaiable, i’ve choosen the one with smaller range but better precision, as i think it’s more important in fine balancing. I’d like to have something that is stable and not swinging back and forth. (more…)

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.
