First, small, grippy Vex wheels to replace the small, low friction wheels
would be high on my list. We participated in a non-First,
Robotics competition, Robofest 2006 - LTU, Southfield,
Michigan and were unable to use the VEX platform because
it required a small profile robot (smaller than squarebot) with
higher traction than these two, small, wheels provided.

Second, would be red, keyed analog/digital pwm extension
cables. I know Vexlabs sells extension cables, however,
we built our own IR distance sensor from Sharp GP2D12
sensor and would have preferred using the red, keyed
cables that cannot be purchased outright.

Third, Tank threads with increased friction, adapter kit.
The Robofest competition occurs on shelving unit boards
obtained locally (5/8 inch thick, three/four feet long -
costing about $10 - Meijers, Lowes, Home Depot). These
boards have thin, laminated, smooth, white coating.
Email recommended McMaster 2126T1. Will look into.
