Me and a couple of friends decided to enter into this competition.
The task was to drive a vehicle along a track to a station where an analog voltage level was to be read. The voltage could take four discrete values and it determined which metal strip at the other end of the track should be shorted.
So the designers of the competition had planned it so that vehicles would be driving back and forth, getting values and shorting the corresponding metal strips. The vehicle that got the most shorts correct in a set amount of time would win.
Me and my friends decided to go with an “all or nothing” strategy. We chose to design a vehicle that drove only once to the voltage measuring station but it would drag lengthy wires with it that it would connect to all of the strips at the other end. I successful, it would then read voltage levels and short strips as fast as it can without moving back and forth. This design would either win by a landslide or not get a single point (if the connectors wouldn’t stick to the strips)
Unfortunately, the wires were cut to a length that was slightly too short. This meant that our vehicle never made it all the way to the voltage measuring station and we didn’t get a single point.
Valiant effort though !
