Simple maze solving robot...

Solve a maze
Cost to build:
$35
Time to build:
48 hours
Weight:
300 grams
- Actuators / output devices: 2 dc motors
- Control method: Atonomus
- CPU: PIC18F2550
- Power source: 11.1V 1500mAh LiPo Battery
- Programming language: Basic
- Sensors / input devices: Six I/R phototransistors, I/R modulated ligth detector at 38Khz.
- Target environment: Indoor. On a specific scenario.
(Sorry for my english...) This is a simple maze solving robot that I made for an internal robotics competition on my university.
The maze was made with white lines on a black surface, and the robot must find the exit avoiding some obstacles (cubes of wood). If the robot detect an obstacle, it must turn back and recalculate a new way for find the exit.
The maze is previously known before the competitions start.
Some materials:
- 6mm acrylic.
- Black paint and foam.
- 2 DC motors (recycled from 2 HP printers).
- 2 wheels (rollers from printers).
- 1 PIC18F2550
- 1A dual DC motor driver
- 11.1V 1500mAh LiPo Battery.

Nice robot, I am wondering
Nice robot, I am wondering if it could run faster??

A very nicely built robot,
A very nicely built robot, by the way. (I love the wheels and motor gear, for instance, but the whole thing is quite nice.)

Thanks... Perhaps it could
Thanks... Perhaps it could have a better finish or construction, I did it with little time available.

Which are the line sensors
Which are the line sensors used?

I used 4 phototransistors
I used 4 phototransistors (like 5mm leds) with a white led to mantain the robot in the line, plus 2 phototransistors (from a old computer mouse) for the intersections. I did not have reflective sensors such as CNY70.

nice colour
cool colour....looks like a bat-mobile to me..did it win the 1st place?

Yes, 1st place + 150$ prize
Yes, 1st place + 150$ prize (aprox). =)

How is the maze path stored
How is the maze path stored in your robots memory? In an array or some other interesting way?
Nice build btw. More pics please :)
