Actually you can make a flipper from a servo. I have never finised a complete Ant but I did have the flipper mechanism working. Basically the servo acted like a lifter but the arm was sprung loaded and was held in place by a catch. The servo would try to lift the arm which bent the spring against the catch until the pressure finally overcame the catch and the arm shot up. It actually started as an axe which worked well on the bench but when put into an Ant chassis the ant performed a back flip every time the axe was fired.

Craig, that was the old EntrAnt and it was nothing like the new improve one.

Jono, they have a website, but thats mostly in Swedish.

Gary, I looked att your tech page, but I dont get how I should mount all the things on the flipper arm...

Hi Joacim
The flipper arm is yellow, the servo arm is green. The flipper is hinged to the robots body at point D.
The linkage between the servo and flipper (red) must be free to move at both ends. The linkage could be piano wire or a recycled paper clip, with a bend in the end so it fits in a hole in the flipper.
Unfortunately I dont have any pictures of the linkage on R.O.N.N.Y or RampAnt. If I ever figure out how to take a good picture of the linkage (its hard to see when the robot is complete) I will add some to my site.

Glassfibre is certainly light and is fairly strong, but its main benefit is that it can be moulded. If you can make a shape that will deflect the impact from spinners then you may have an advantage. Carbon fibre is lighter and has been used to good effect. Kevlar hasnt been tried yet AFAIK...
