Electric axe mechanism

[Prophet Of Doom]

I’m currently looking into the idea of building a heavyweight version of Audacious with a fully adjustable tail that has about 180 degrees of travel and can dislodge itself when stuck on the arena wall.

Anyone know of any simple examples of an electric axe/arm mechanism?

Note. It will be shed-build level building

That sounds like the reverse of Shu!, one of my Beetleweights where it had a long arm on the front and was capable of pretty much dislodging itself from anything as the arm could go though near 180. Here is a video of it in action.

I used a planetary gear gearbox in that but I reckon a simple enough spur gear arrangement with a pair of heavy duty chain and sprockets as the final stage would work (I had considered and even CADed up a HW version of Shu!) I think the key is getting a low enough RPM motor that can be further reduced down significantly for that extra torque.
