I don't actually use a gyro for the melty brain system, I use an accelerometer. Pretty much just set the accelerometer up at a known radius, and can then calculate the rotational rpm from the amount of G's the accelerometer sees.

Weighed the parts, then glued two layers of the chassis together, then glued the carbon fibre base on. Bolted it together with servo bolts.

Finally got the waterjet bits back for uMBX



Now to get stuck in an put some guts into it!

A US builder has done a dog clutch based kinetic flipper for a featherweight, you might have success scaling his method down to antweight size. http://www.wa4dsy.net/robot/flip-o-matic I built a lego design about 6 years go as a prototype for a heavyweight, it use a rough method of wedging a dog gea...

After several unsuccessful attempts at a full body spinner I have opted for the slightly easier bar spinner where the blades are bent down so they are low enough to be effective. Bend down over head bars have a nasty tendancy to cause the robot to flip itself on impact. http://media.madoverlord.com...

The old Futaba S3003 servo boards are generally good for around 1amp loads and can handle 9v. They are a little big in size though (25x15x5). I used a pair of them in a super antweight about 6 years ago with no issues (However, no real combat either!).

Thought I'd add my antweight in progress to the list.
