Spinning Top Robotics
One of the ideas I thought worth thinking about is basically a remote control motorised spinning top with an outer shell on top counter spinning to give a frame of reference. The robot would use weight distribution or a moving contact to move in any given direction and the sides would form a blade. Does anyone have ideas on how I could go about designing something like this?
I need to learn through having my first ant weight built and fighting but wanted to throw this idea out there to see what others think anyway. It would be nice to have more risky builds, rather than the safe (because we know they work well) designs to add more variety. That of course isn't a complaint about those builds, rather the fact it is tempting to always do what is known to work. I know my first builds will fall into the safe category for example.

This gives an idea of what somebody else had also been thinking of. The only other thing similar would be the beyblade toys that can be controlled when already in motion.
Here is a a video that shows how this form of motion can stabilize (as well as move) such a bot if it were built.

Whether it works or not its a novel and interesting concept none the less, definitely a crowd pleaser at events. I'm very interested to see how you'd go about this and whether you could get it to work. I don't know much about it but you could probably get your translation from a reaction wheel. How would you go about getting everything to fit in it? Pancake motor with everything else ontop/around? I guess you would only need two motor drivers, one for your reaction wheel and one for your spinning motor. You might need a custom solution to map your reactionwheel control to understandable controls on your transmitter, you could probably do this with a microcontroller like an ATTiny or PIC. Then you need to fit your battery and receiver as well. Quite the challenge but if executed would be awesome.

Really cool concept. You should look into pendulum drive or flywheel as you already have been thinking about.
I would suggest that you take a look on how the BB-8 internal drive mechanism has been developed. It's all around on the internet and there is a special facebook group for it too.

Thank you. Yes the BB-8 mode of transport is interesting. It would take a very very skilled team to weaponise what is essentially a rolling sphere. It could be done, but harder than this idea.
I just want new ideas that fit with what is possible today.

I might actually try a POC by using a small gyroscopic helicopter. Is there anyone any good at CAD or programming that might be interested in working on such a project? There is no way this could work without a small computer of some kind either remotely or on board.

Although this is only ONE of the crazy contraptions I was thinking of. Other ideas were inspired by these videos.

Even the self assembly you see in transformers/power rangers (I really don't like power rangers - this is just a helpful example) is an interesting concept. Think of small armbots, a main body (using tank tracks and a fold down structure) and a head.

Not to be an idea killer, but I don't see how any of the other concepts will work in a robot fight, where a robot benefits from being simple constructed to be reliable and mass also has a high impact on the performance, just like martial arts, I don't see how ten 8 year old boys will win a fight against you unless they go straight after the nuts, then you have to figure out how that projects to robot fighting. But would love to be proven wrong!
But here is your Robot :mrgreen:
