I saw that on Scientific American several weeks back....pretty neat Segway type device

[Mat Wellington]

Do able with openpilot
Replace the 3 drive wheels with three servos, that have been modified to continually run in both directions when you apply a signal greater or less than 1500 us, same as a boat winch servo

Then use a tricopter mix for pitch/roll and apply yaw to all three

[peabody124]

I think you could also use an RC car ESC that can reverse directions if you had it geared down enough.

[Mat Wellington]

yea, not sure if they would be quick enough switching from forwards to reverse, as they normaly have a brake-pause thing going on.

to me servos are easy, its a motor/esc and gearbox all in one

was going to use two servos like that to make a RC paddle boat

[Adverse Effects]

did you see the rack of PCB's in that thing LOL look at time stamp 3:02 and that is only the top rack of them there is at lest 2 other levels in it



and they still needed a external computer as part controll

Weren't you looking for a new challenge Mat? Just saying...

pokes Mat

[Mat Wellington]

need to get my foot out of my mouth

hmm, dankers may need to dream up another award.......................

[Mat Wellington]

you guys are a bad influence...... just ordered a set of 4 servos and foam wheels

should have brought more, because you can also use these to make a wheeled vehicle if you want to test out copter control for that

[3rdeyepro]

Awesome Mat! Glad I could inspire someone to try this.

[dankers]

Unreal!! Can't believe you are going to try it, wow.

[3rdeyepro]

Will it work with regular wheels or does it need those special roller wheels in the video? Or are you thinking of a different design?

[Mat Wellington]

i am hoping that on a small scale i can get away with side ways slipping of the dead wheel, but if not, it will take a bit more work

ROFL

[nick_a]

omni-directional wheels can be had fairly cheap, http://www.robotshop...eel-40mm-2.html
will be fascinated to see if this works, robotics has always been my other love

[dankers]

Other? Other? Were all about flying robots! That's what the Revo really is, a flying robotics platform. CC still needs pesky human control, but Revo will dispense with all the humans. Ah, that came out wrong.

[Mat Wellington]

great link, thanks for that

............. but Revo will dispense with all the humans. Ah, that came out wrong.

hmm....... just workin a small project called "star net ".... gunna network a whole bunch of revo powered robots together....
