Skeebot humanoid robot

thingiverse

Skeebot is a work-in-progress humanoid robot designed with several key objectives in mind: affordability using readily available micro servos, reasonable expressiveness allowing it to walk, kick, wave its arm, or grip objects, but without overly complex hands. It should be around 10 inches tall and compact enough for fun use. See the uploaded images featuring the shoulder-clamp, armbox, hand-and-clamp, and prototype torso. The legs and head are still in development; my 3D printer is currently down, so I need to repair a few issues before testing those components. Edit: Currently, the torso serves as an empty box for containing batteries and electronics soon. In the printed photo taken before stepper drivers blew up, the arm and shoulder were working nicely - rotating around the shoulder, moving at the shoulder, and moving at the elbow. The leg is more of an arm now with a foot instead of a hand; however, it needs significant work yet, including writing code to enable walking by storing actions rather than just flailing around. Electronics-wise, I utilize my homegrown PCB for driving it, but any servo-capable electronics should suffice (Arduino, r-pi, etc.). The torso is currently a printable box where you might fit the electronics and batteries into, but as I design it, I'm using an umbilical cord of servo wires out the back. Once the body works fine, I'll resize the torso to house the electronics independently. I'm concerned about balance once the electronics are all in place, affecting walking and bending; so I'll address that later. Servos used are Emax es08maII - very small yet strong with metal gears. Analog or digital servos work well. The es08maii costs around $5-$7 USD or $10 CDN in common locations. Plastic used is PLA, but ABS or other types should be fine too. It works well with the PLA 'threaded' look of 3D printing, and ABS can achieve a 'gloss finish'. SCAD files - I'll upload them along with customization instructions later after retesting builds.
