Walle is an autonomous custom-made, laser-cut rover that avoids obstacles and tape borders, looking for a cross-shaped pattern. Its barrel has the capacity of 6 ping-pong balls and it uses
a catapult-like shooting mechanism shooting toward an item carrying an infrared beacon.
An infrared beacon detector indicates the robot’s opposing direction and helps targeting the item for shooting.
Walle uses transresistive infrared diodes and LEDs as a tape sensor.
It utilizes two infrared proximity sensors and two grey-scale encoders. The beacon detector is custom built for the frequency of the beacons (20000 Hz).
