Tripods are coming ... by Ablapo Mar 16, 2013

Description

With this triangle connector you can build a robot with three servo legs.

(A frame for quadrupeds is included, too.)

Can it walk? I don't know, yet! :-)
Do you have ideas of a good walking method for tripods?
And it's a three finger robot claw, too!

Wow thanks, he has some pretty cool concepts.

Thank you. If you are interested in design and minimalism, then search for "Claus Mattheck". He is a master of the bionic static optimization.

I love your minimalistic design! Inspiring.

Instructions

For this tripod you will need 9 metal geared servo motors (~12g).
Assemble each leg. Then mount the legs on the center triangle part.
The provided leg parts are optimized for servo gears with a diameter of 4.8 mm. You have to melt the inner surface of printed part using a tiny flame, to mount it on the servo gear. The part should not fit on the servo without melting it. If your servo gear's dimensions are different (>0.05 mm), then create your own version from the ancestor scad files.

You can use the four M3 holes of the triangle to mount the "head" (not included).

it will have to step quickly. You will probably have more luck going straight if it lunges/hops forward off the single back leg and lands/catches itself on the front two. It's going to have to hop like a frog or rabbit. The other option is to put wide feet on each leg so that standing on two legs will offer more stability like a cane with more than one foot.

I was thinking about an additional balancing weight ring on top of the robot. That could help to shift the weight to one side and decrease the falling time of the robot when one leg is lifted.

If you can shift the weight mostly onto two legs you may be able to slide the third leg. Otherwise walking on three legs will have to be very dynamic, like galloping.
