How stiff is that arm? Looks cool though, good work.
Wow, looks like 696 has done it again and created another killer robot. Is that a Fisher-Price I see? Is it sitting on top of two CIMs?:ahh: And what the heck is that pneumatic cylinder next to the gearbox for? And look at all those rivets, reminds me of an airplane.
Also, now that I look at it, are those custom machined wheels?
Anyway, enough of my babbling, what do you think?
EDIT: The arm is very stiff but incredibly lightweight. The arm segments are made .050 aluminum sheet metal that has been formed into C channels.
