Spider

thingiverse

This impressive eight-legged spider robot is crafted from 3mm ABS foamboard and boasts a design that allows it to walk regular stairs while lifting simple loads. The build process requires CNC machining, lathe work for axles and plastic parts, a powerful servo controller, and a potent battery pack. Created using dxf files that fit onto A4 paper, the robot's parts include cross sections for each upper leg to reduce torsion and make walking easier to calculate. The hip joints are particularly challenging to assemble but patience and test builds will help ensure success. Additional parts are needed for axles and servo mounts, with specific servo cutouts in the design. Photos documenting the build process can be found online.
