Autonomous robot
The goal is to make an autonomous robot, based on a snow plow R/C model, randomly moving in a space (rooms, corridors, ...) while avoiding obstacles with its sensors.

Hardware
- Snow Plow R/C model
- Arduino Duemilanove
- IR sensor: Sharp IR GP2Y0A02YK
- Ultrasonic sensor: SRF05
- Servo motor
Detailed description
Mobility: provided by snow plow original tracks and motors.
IR sensor: mounted on the servor motor and used to scan an angle of 120° in front of the robot. Used as a kind of long distance proximity sensor to detect obstacles in advance and let th AI take the right decision.
Ultrasonic sensor: used to detect only front obstacles. Used for emmergency stop in case the IR sensor miss something.
Servo motor: used to sweep an angle of 120° (60° left ans 60° right) in front of the robot.
Goals
In a first time, move avoiding obstacles.
In a second time, anticipate obstacles to move more lightly avoiding zig-zag between walls/obstacles.
