Arduino linefollower prototype.

This is my first entry in letsmakerobots.com but not my first robot. I wanted to make a robot with a pcb as chassi, like 3pi, but I wanted to be able and take the microcontroller and use in other projects. I also wanted the mindcontroller to be an Arduino series mindcontroller. This is the prototype and I hope one day I will print a pcb for it. These are the componed I used for the robot :

• 1 x Arduino Nano
• 2 x 30:1 Mini Metal Gear Motors
• 1 x Pololu 1/2" Metal Ball Caster
• 1 x L293DNE
• 1 x Lcd 16x2
• 1 x 74HC595 shift register
• 1 x buzzer
• 1 x 7805 voltage regulator
• 3 x CNY70
• 3 x led
• 1 x ir receiver

Its functions will be linefollowing, maze solving, remote control with ir and maybe I will mount a servo with a sharp ir sensor for autonomous navigation. When I will finish programming I will post a video and the code.

UPDATE 1 MARCH  2011

The new battery is here ( 7.4 volts lipo 850 mah) so I made a small video using a very simple code.
