Getting walkers to turn?

[somepersondunno]

Anyone got any ideas on how to make walkers turn without needing to resort to non-robotics methods, like wheels or RCS or wacky things? 

 

I'd love to have a semi practical Dunar walker transport.

How about you have three KAL-1000: one for walking in a straight line, one for a right turn, and one for a left turn?

Hmm, fair enough. I've been trying to make a walker that'll actually WALK but if you could make the legs capable of movement sideways I suppose it could translate well. I think it'd be easier for a spider type mech.

You could make a hinge section down the middle of your walker and use a separate axis to control it. This way you'll have a fair amount of precision.
Another way would be to make axis-controlled-hinges at the shoulder(s) and/or hip(s) joints.
Of course you could combine the previous 2 methods to have something as close to reality as possible which can make a super tight turn.

I figure, the only challenge with the above methods will be to counter the slacking of the structure the hinges will give. Especially the middle section.

Show us some pics! I'm curious.

I would make the left hand side have one KAL controller, and one for the right hand side. And then you can swivel the walker around by only playing one side controller.
