Team Kaizen - The Honey Badger

[Outlaw]

Ah, I see I see. Well, as soon as I get my robot on it's wheels, and I put my prototype mechanism together, I can give you a look at what my design is, and you can always give it a shot yourself. Also, start with hand cranking instead of using a motor, else it'll just do what happened in your video, as cardboard isn't really designed to be used with motors like that. :P

Deadliest weapon in the world right there

Dont knock it, papercuts really hurt!

Dont knock it, papercuts really hurt!

Hahahahaaa!

I had tested it with a hand before I filmed the video The only issue is that with a hand motion, I couldn't get a good idea of what the motor would do in place. It was a very quick 'n' dirty concept test.

Actually... I may have a way to preform a reciprocating action... I wonder if I can get it done before Maidstone? Watch this space.

I love we're all just building n messing about in front of corrie lol :-) love the shape of you're robot it's like the perfect shape.

[Ocracoke]

Hahaha, thanks The shape does look purposeful when zipping around the arena but it is slab sided at the moment, going to need some wheel guards so it can't land on its side.

[Ocracoke]

Hmm... that could work, thanks for the suggestion. I'll see about modelling a scale version first and go from there.

[Ocracoke]

Here is a rough and ready proof of concept of the mechanism.



This fulfils the brief I want from a axe for The Honey Badger. I do have a concern about the amount of sweep the axe might have but I guess it will come down to how big the slot is and where the axe pivot point is in relation to the motor.

Excellent to see that something from 1850 still has a place in modern RobotWars

I'm still experimenting with bigger diameter drive wheel and longer arms for more thwacking and also the placement of the bar pivot. There are some other linkage mechanisms that work but are more complicated and then you run the risk of things breaking and being overly complex.

[Ocracoke]

I agree, you don't want overtly complex mechanisms that can break/shake loose during a round.

For this application, I think I need the pivot point immediately behind the drive wheel to try and get the axe as far forwards as possible. Any issues with freedom of movement can be rectified with a longer axehead if it comes to it, might end up more scythe looking in the process.

[adamclark]

A variation on a fauchard would suit quite well instead of an axe.
