Build
Atech crab
Sesame, the open-source walking robot, with the 14-port board as its brain. Eight servos, a face on the screen, and an orientation sensor that keeps it walking straight.
Everything in this build comes in the Big Kit: $159. The 3D-printed parts are not included, but the Big Kit comes with a free 3D print voucher (the Chunky Kit with three), a custom casing included. Design yours with our free, open-source AI CAD tool, or email [email protected] and we will help you print it.

What it does
- 1Four legs, two servos each. The servos plug straight into the board, no servo driver in between.
