Of course, this year's system has some *minor* improvements.  |
Clarification:
All this braking system is "lock" the gearbox and wheels. This turns the wheels into brakes that act on the carpet.
Limitations to this?
A robot with a higher coeff of friction can push you (As long as their gearbox is geared low enough).
Many teams drop "super traction" type brakes in lieu of this. (filecards in 2002, sorbothane in 2003)
Also--
If the drivetrain gearbox is geared low enough to "slip wheels" there is NO need for this locking system. A high torque gearbox can do the same job.
