This is my first robot and is just a test platform to experience with an autonomic robot. To test the robot I put him under a table with chairs and it has to get out without hitting a chair leg or a table leg.

Body made from plywood
All pcbís are home made
Every wire is made with pcb connectors (easy to test new things)

Drive train:
-2 jumbo servoís with all electronics removed (only motor and gearbox is used)
L298 Hbridge for controlling the motors.
7.2V NiCd battery pack for power.

Things to be changed in the near future:
- The IR modules changed by better type Iím having problems with the SFH506
- Replacing the BS2 (memory full) by the Java Stamp (Iím a java programmer)
- Rebuilding the ultrasonic distance sensor to be stand alone (now itís ping and receive is done by the BS2)
- Adding some RF communication between the robot and my pc.
