First time building a flipper robot

[Danny B]

Ok, I think I have a basic design figured.
It's inspired by American middleweight T-minus, and I think it should provide a relatively compact shape capable of both running inverted and self-righting.
The whole machine should be about 35-40cm long, with a 50mm bore, 100mm stroke ram powering the weapon. According to my calculations, a 10bar system should deliver about 60kg of force at the tip of the arm.
