Why is the record 64 seconds, Ive seen faster?
The Guinness World Records rules state that the time taken for the robot to scan the cube is to be included in the final time. I did not build RuBot with the intention of making or breaking any records so this time is quite slow. It takes RuBot 8 seconds to pick up the cube and a further 17 to scan it and find a solution. This means that 25 seconds are included in the total time. RuBot solved the cube in 39 seconds (a little slower than average) so that gave a total of 64 seconds for the record. I think the scan time is a bit unfair because it is not part of the normal solving rules for humans but I can understand why it is there.
