TBH of I were him I woulda made the shell more jagged / rugged so in case his teeth idea doesn't work he'd have some form of attacking still, even though it's basically metal sandpaper.
The dome is a thing that I purchased (it's a hemispherical cake mold), so I can't just make one whatever shape I want. I'm limited to attaching things to it. Ideally I'd weld a big ridge on the outside but welding to thin metal is tricky. Also we have to worry about weight - we're probably only going to have 50g-150g left to play with (total weight 1360g).
So is he going to enter this into some kind of robot fighting thing?
There is a robot fighting thing in Seattle, but I'm not sure I'll be finished in time. Also I think it has limited spaces. If I don't make it there's Robogames 2017.
so wait is this like a pre-desgined robot or did badspot come up with this himself
This is an original design, cobbled together from a mix of RC cars, quad copters, robot parts, and restaurant supplies. There are quite a lot of kitbots at the 1lb and 3lb levels, and they actually win competitions pretty regularly.
is he gonna put this on the TV show battlebots? it looks as if he is.
We're about 247lbs undeweight for that. The dome is 160mm in diameter.
