A different method of propulsion using gears

I’m planing on building a robot with that kind of mechanism, what you cant see on that video is that its actually only the half part of the legs. However I fail to see how it is maintaining its balance…

Also google Mondospider for more information on the subject.

It seems that it is maintaining its balance by some sort of wire-leg in the back, that’s a bit of a downer…

Very cool, reminds me of a

Very cool, reminds me of a crab. Maybe you could try three or four sets of legs so it doesn’t have to use the fifth leg?

Yes its using a paper clip,

Yes its using a paper clip, or something simular, for balance as Geir said. pause and youll see it.

I’m building a 3D printer, and this seems like it would be pretty easy to make once I finish it. Of the three gears visible in the movie, the center one is powered, right? And the opposite side looks like a mirror image? I’m guessing the motor is somewhere in the center powering a shaft that turns the two middle gears.

If you had two of these things, how well do you think you could turn with a differential drive kind of thing?

edit: this thing is giving me a million ideas! like maybe it would be better if the inner 4 legs on an 8-leg system were longer. Or, if I angle the legs outwards, I might be able to make a 4-leg version balance by itself. Maybe with a bevel gear in the center? hm…

Smooth!!
