Servo - October 2011

and shrapnel out.

There was only one day left before the bots debut at the Schiele Museum back in July, so I quickly put together a wedge using two chunks of 1/2” nutstrip, some UHMW, and a sheet of 1/16” 7075 aluminum. This was attached to the bot using a short length of 1/4” titanium rod. This was a tight fit in the holes and I thought it would hold up alright, but combat was to prove otherwise. The bot — now named Trilobite — was ready to go (Figure 13).

BUILD REP RT:

A Team Building Exercise

● by Pete Smith

My Kitbots bot hockey team “Team Scotch Pies” had competed in one event and taken part in a couple of demonstrations, but the bots were retasked for a summer camp and were less than ideal. The bots were four wheel drive, but only used two cordless drill motors and they only weighed 8 lbs each (rather than the allowed 15 lbs). It was clear when they first met other custom-built hockey bots that they were simply outclassed.

A planned demonstration at the Durham Museum of Life and Science in March ‘ 11 gave me the impetus needed to build a new fleet of competitive bots.

To save time, I used as many standard Kitbots parts and familiar processes as I could. The finished design (Figure 1) uses template routed polycarbonate panels joined to together with my 3/8” nutstrip and four 18V cordless drill motors in the budget motor mounts, plus 3” Colsons with the standard hubs. The top and bottom are identical as are the two sides and the front and rear
