Next week's video for Patrons is the logical progression from my reaction wheel video. I'd really like to use reaction wheels to stabilise some other types of robots in the future though.

Just a thought if you wanted a bit of an engineering challenge. Reaction wheels are used heavily in space. Whilst I accept a space project is likely out of budget (shame!) what about a neutrally bouyant ROV that uses reaction wheels for keeping upright allowing it to have a payload of...anything that requires orientation (sea floor mapping for example)

It should work with anything, although IMUs won't work well in low gravity of course ;-)

no - i assume spacecraft, etc use gyros etc and a whole bunch of mercury switches or similar for easing? Don't actually know though How accurate could you make it I wonder? thinking of some kind of tight rope (slack line might be easier) single wheel'd robot? Because, you know, its fun

I think it would balance on a wire/rope because it doesn't move sideways to balance. The reaction wheel part would probably need some returning to take account of any movement in the wire though because the floor generally stays still.

It will be interesting to see how well this would work in a biped robot

Yes it would although the wheel would need to constantly accelerate to hold it off centre. This one can actually steer... just about.

Interesting! Can't wait to see this!
