RC Jansen Strandbeest

Description

This Strandbeest was made using G10 and Delrin cut on my homemade CNC router. The motors are Pololu 20D 73:1 motors and they are powered by a pair of their simple motor controllers. The leg joints use nylon shoulder washers to help reduce friction and wear. I have a ton of aluminum standoffs so those always tend to make it into my designs. The Strandbeest runs off of 2 cell lithium batteries. The bevel gears are from servocity.

I always regret not taking more photos during the build process. I'm sorry if there is something you wanted to see that I didn't get.

Here are a couple videos:

This is with the current 73:1 20D motors:

This is with the old 29:1 20D motors (way too fast, not enough torque):

I know some people don't like thingiverse but it is easier than signing up and figuring out GitHub. Here you go http://www.thingiverse.com/thing:719812. If you need more pictures for assembly or what parts I used let me know.

Are you sure? yes | no

"One does not simply... figure out... git" ,o) God knows I haven't... years later. Thingiverse is fine.

very cool. Do you have the files in a public github?

Are you sure? yes | no

I'd be happy to release the DXFs so you can make your own. I'll also try to get some more detailed photos and a basic BOM to help with assembly. I'll post it when it's ready.

Outstanding, VERY impressive, are you planning to release the build info?
I want one (or even two!)

Are you sure? yes | no

Perfect! I love the gait with the 73:1 20D motors! Do you have any of the patterns? I'd love to cut one out on my shapoko 2 (as soon as I finish building it!)

Are you sure? yes | no

I love how those walkers have smooth leg movements, very much different from how we tend to program the servos. No sudden movements, slowly accelerating and decelerating along their path...

Are you sure? yes | no

Wow! I've always wondered how this would look like, great job!

Could you add the videos to the details section - this way they get embedded on this page.

Hm, now I want one :D

Are you sure? yes | no
