Making a four-legged walker inspired by Kame and Max the Megapod, I'm teaching myself OpenSCAD. The goal is to create a walker that's easy to customize by adjusting parameters in an OpenSCAD script. I also want to experiment with cheap skateboard bearings and standard servos. On September 22nd, I mostly focused on modifying the OpenSCAD script to make it easier to tweak dimensions and consistent throughout the script. By September 25th, I tweaked the servo dimensions a bit – the prototype print was a little tight on flange length, but the bearing seated nicely. The first concept of the joint from body to suspended servo was developed. A single piece joint didn't work out, but two halves are great and much faster to print. Tweaks to the body have servos seating nicely in the body. Next steps include modifying the body where to mount a battery/controller – servo to joint interface – thinking about using simple gears. On November 20th, I'm trying to make the servo mount more modular – if I can get happy with this part, I can include it, angle it and mirror the part in OpenSCAD. By November 21st, I got rid of the cut out in the cylinder – thinking about how to mount control boards and battery – thinking about carving slots into the sides of a rectangular body to slide the boards into. I need to decide on a battery for the servos and for the controller. On November 24th, my first attempt with a rectangular body was made.
