New GMPW Wheels!

No more rubber band tires for us! We've invested in getting our very own wheels made for us, with molded-on thermoplastic rubber wheels!
These wheels are slightly larger in diameter than the old style, measuring 69.2mm (2.72") diameter and 7.65mm (0.30") wide. Ah, but how good are they? They're definitely better than the old style! We know from head-to-head tests that these have better traction than the rubber-band tires (definitive numbers are coming...). We've also spun them up on our lathe to see how true the mold process is, and they're quite true - no visible wobbling!
A new enhancement is a built-in opto-reflector 32-step pattern! Built to be bolt-on compatible with the Wheel-Watcher series of wheel-encoders, all you have to do is paint the groove white (for dark plastic wheels), and scrape away the raised surfaces to generate a sharp, accurate 32-stripe pattern!
Did we mention that there was no increase in price for all these enhancements too?

Harold's "Tank"
Harold Ilano built this SW2.2 / VBug inspired 5 motor walker named "Tank", and just recently announced it on the BEAM mailing list. It's a very effective and quick device - nicely done, and well worth a look-see. It still impresses me what we can do without a microcontroller...
New Wheels
Remember those bad-boy wheels you saw on Strongbad? Well, they're now available! But be warned - we don't have the sleeve to fix the 2mm shaft to 1/8" hole diameter gap, so you'll have to improvise something yourself. Otherwise, your robot will have a bit of a lope to its roll!
