[Abra Cadabra IV]

We've had issues with the wobbly bushings, encoder cables, and the communication between the NXT and the motor controllers (the last of which lost us the final round at Los Angeles, argh). There's also been problems with the wires coming loose; crimping them onto the motors helped but there's not much we can do about the ones that fall out of the motor controllers even when fully tightened.

We've also had issues with the power switch, which is fine in most respects but needs to be far stiffer, as it can be turned off by a well-placed puck, not to mention another robot. (We thought we had ours in a spot where nobody could get at it. We were wrong.) A couple teams lost matches at Los Angeles last weekend due to robots accidentally getting turned off.

On the flip side, we now have several funny stories to tell regarding interesting failures...
