weapon motor: 1 speed 900 on 24v
weapon: 1.2kg stainless steel spinning drum
ESC: sabertooth 2x25
wheels: 100mm blue wheels
armour: 20mm hdpe armour and bulkheads (i know nylon would have been better) and an ali base plate and lid

Very nice. Are you just using o-rings for weapon belts though? You'd probably be better off with timing belts & pulleys, o-rings are almost definitely going to jump on pulleys with flanges that small (and lose traction)

[Max]

At the moment I will just use 2 o-ring belts and will see how it goes and it is supposed to slip a bit to protect the motor but may upgrade to 1 timing belt if it proves ineffective

Looks good, I'll have to build one eventually

forgot to mention, everything in the first picture together ways 12kg but that doesn't include motor mounts, screws and bolts for holding everything together or the large bolts for holding the bearings in place so weight might be tight!

It's very disheartening when you weigh your components and they alone are near the limit!

Got a decent set of components there for a drum bot. How is the drum constructed? Trying to work it out but it's difficult from the pictures. Have you taken a sheet of stainless and bent it around?

[ewan]

You could potentially save a lot of weight with li-po. And can't quite see from the picture but you mightn't need that much HDPE?
