For all the "haters" and non-believers:
The potential energy (for a minbot weighing 1.5kg) at the top of the tower minus the potential energy at the deployment line is about 34.4 joules
2.337m X 9.8m/sec^2 X 1.5 kg = 33.4 joules
According to this thread:
http://www.chiefdelphi.com/forums/sh...ht=motor+specs
the motors run at about 21 watts w/o gearbox at 14 volts. I believe that informtion is trustworthy and it is well documented, so I will trust it.

With two motors thats 42 watts total, so in theory, the bot could go up the tower is under one second. The video shows about 1.1 seconds from deployment line to top.
It's Possible

I am curious about what looks to be the turbocharger kicking in partway up the tower, that is odd. Could just be the angle of the view that makes it seem to go faster.
