The goal is to experiment with programming a robot with different behaviours resulting in a sumo wrestling LEGO robot.

We created another robot as seen in the image above. The original purpose of the robot was to test the ultrasonic sensor, since it was difficult to do this without having an opponent to detect. We also had a lot of use out of it to help us think of ideas and in general test our robot without help from other groups.
It was not possible to test the robot against an opponent, after completion. We did test the robot against different opponents during development. Video [10] shows a battle during the final stage of development.
# Conclusion
We have been very limited by the weight limitation, because of our vast amounts of sensors and especially the rcx cables. We have found that a motor mounted ultrasonic sensor is simply too slow to use in a sumo fight, a solution could have been to use two ultrasonic sensors, but we did not have weight or sensor ports to spare. Most interestingly is our experience with using multiple touch sensors connected to the same port through rcx cables. It was surprising how well we could distinguish the sensors solely because of small differences in the measured raw value.
