My Mindsensors GlideWheel-M decided to die on me at a most in convenient time whilst building the Mark II version of my Bin Emptying Robot. I was forced to use limit switches instead. After talking to Deepak Patil from Mindsensors, he suggested I take a knife in hand and disassemble it. The process was straight forwad enough, provided you kept the blade to the edge of the sensor. You are restricted to around 5mm at the sensors edge. Go any further in and you risk damaging the electronic components.

LEGO Mindstorms NXT Bin Emptying Robot – Mark II    Send article as PDF   
This is a LEGO Mindstorms NXT “Bin Emptying Robot Mark II”. It is part of a larger project I have been working on, my “Ball Sorting Factory“. A forklift delivers full Bins of balls to be emptied. The Emptied bins are then taken away to the processing facility to be refilled. The Mark I version worked well, but it was slow and very noisy, unlike this version. Also this version uses a “Ball Repository” to store, mix and reload the Production Line with Balls when the “Ball Sorting Factory” needs them.
