Corvis (temp bot name) rough ideas.

[Bacon Wizard]

You could try recessing the spike into your robot so it has ample time to accelerate before hitting anything.

That's the plan. But I don't yet know how large the bow itself needs to be to generate the required forces. That'll pretty-much dictate the rest of the bot's design.

I'm counting on the reverse-energy configuration to help. Here's an example of perhaps the market leader for ordinary bows right now. Imagine mine with the arms 10 x thicker and the whole thing narrower.



Cocking it is also a concern. I could end-up with something that takes 30 secs to re-cock but which nobody want's to get hit-by. Or it could be weedy and quick. I need to do some proper maths.

Has anyone ever attempted a bot that anchors itself to the arena floor with suction for better weapon-deployment and/or anti flip?

Magnets....

Yep, John Reed with Killerhurtz -see the movie Antazz posted.
There a turbine and extremely fast running motor created suction between bottom plate and floor.

In Beta he used a gazillion magnets.


But anti-flip. Worst case scenario robot and piece of floor get airtime. The flippers atm are "powerfull".

Yikes!.....

Very interesting bots, I like the thinking. I've been looking at gyroscopes also.

Your avarage heavyweight FP flipper uses a 100mm bore ram with multiple feeding valves.

5*5*pi*55=4300 kg of force.

In feathers a 50mm bore ram ain't an exception. That's a ton of force...

[Bacon Wizard]

Doesn't seem much point trying to resist it then.. concentrate on SRMECH innit.

I can see why people enjoy FW.. power to weight ratio must be through the roof.

Hannibalito 4 uses a 78mm bore FP ram.
Containing those 2.5 tons of force ain't that easy.

In our Robo Challenge arena we have a 4mm hardox floor which means magnets are a good bet and alot of people use them. In heavies, Its probably not worth looking at as the wooden floors get damaged and your likely to be sucking in bits of dust, broken bits of MDF/Plywood etc and cause your self problems.
