My shuffle walker Crabulon. This requires N20 motors to function and some elastic bands or hair bands for the feet. your need M2 screws as well to hold it together.
To build the complete robot you will need.
1x base plate print
1x of each side fame
2 x of each side
2 x of motor mounts
2 x spacers
2 x of each cog
16 x of the cam
16 x of each leg.
You may need to modify the chassis to fit your own electronics and power.
I built it to compete in UK ant weights and when printed out of PLA it was within the weight limits. I have not printed this in ABS but it should work.
When assembled a little bit of oil or grease seamed to help the mechanism run. I would recommend bedding in the mechanism. You may find it wears after some time.
Let me know how you get on with it and if I can help with any issues you have.
