My Easter holidays have begun and so has the race to get this machine finished for the Yeovil Robochallenge event. Here's how it looks today (apologies for poor quality, I'll use my camera instead of my phone next time!):





So the set-up will be two slightly modified 9.6V GR01's for drive (built into the chassis rails), a 14.8V 4000mah Li-po for power and a Scorpion XXL (in a heat-sunk & fan cooled enclosure) as the speed controller. The weapon/scoop is powered by a GR01 slaved to a worm reduction stage (hence at 90 degrees to the weapon shaft) and then slaved again by chain to the shaft, a total reduction of approx 1200:1 from the motor. I've had the worm-stage housing laser-cut from aluminium which isn't in this picture.

The end result should look pretty similar to my beetleweight:



Tomorrow I'll start cutting up the 4mm Hardox which will make up most of the exterior, then begin welding the scoop, front axles and side arms together. Lots to do!
