NXT "Can-Grabbing" Competition


Proof that the race doesn't always go to the swift. (And that the word, "bingo" has the same meaning in German and English). :)

I liked it, how does the robot know where the cans are? Or do they just run into it =D. Brilliant Idea.

It could be that it looks for something that "sticks out" distance wise with the ultrasonic sensor. For instance:

3344455116678

If you imagine the numbers as ultrasonic sensor distance readings over time as you are spinning, you can notice that the two ones "stick out".
