hi guys! i'm working on a project. it's a biped (two-leg robot). i think the animation(click on the image) shows the most but.. that on the top is a hard disk platter on a fast spinning motor. it must act like a simple gyroscope, keeping the robot straight.. i'm not quite sure, if it's gonna work, but i'll try :) i have all the parts and i have allready build the"body", but i don't have a torx screwdriver to unscrew the platter :( so till i find one i have to imagine only what will happen :) any ideas? please tell me, if you are sure, that it's not gonna work. why? 10x!
