I built this robot to have a platform for starting to learn AVR microcontroller programming. I ordered
the parts as a kit from Make magazine. I put the robot together and soldered all the electrical components
into the circuit board.
The tiny wanderer robot has two servos to drive the large wheels. Position sensing is done by two IR LEDs
and two phototransistors. The robot looks to see if the IR signal from the emitters bounced off an
an obstacle. When the IR signal bounces it can be detected by the IR sensors.
The brain of this robot is an ATtiny85 microcontroller. I've written C-code to query the IR sensors and
drive the servo wheels accordingly.
Currently the robot can avoid obstacles, stay on a table and follow a line.
