beetle size lifter

[Ellis]

I designed and built Kinematic Events' five pay-to-drive robots. Two of these were front hinged servo powered lifters. I used this servo: http://www.hobbyking.co.uk/hobbyking...arehouse_.html

Those machines weigh 2.5kg and self-righting requires substantial torque, though not wanting to sacrifice speed or range of motion I fitted springs to help the servos.

Straightforward enough mechanism and you can see the torsion springs built into the hinge at the front. It had no issues flipping the other 2.5kg robots before springs, so it should be great for the beetle class at a whole 1kg lighter.
