Robot Tank Treads

pinshape

I'm currently testing out my own TPU filament, and it's working great! For this proof of principle design, I utilized long M6-threaded screws - the hubs/wheels were screwed directly onto them - and ball bearings. The fuselage isn't a good design at all, but rather a fast base to test the hubs/wheels/tread... the drive-wheel was fitted right onto the geared-motor axis. Various flexible filaments might work well, making sure they're not too stretchy since they may not stay on the wheels/hubs. I used my own: http://www.creativetools.se/pi-etpu-95-250-carbon-black-1kg-se. It has only 250% stretch and also 95 Shore A. It is also conductive, and if you make both the hubs and thread in this material, you'll be able to handle the static electricity that's built up when plastic moves...
