Spine Robot Work Log: January 2015

Finished making new hard tires for the Spine Robot Mobile Platform. The originals were made using small Jet Aircraft tires. While these tires are almost 2" thick and 16 ply, there was too much flex when making tight turns, leading to the tires folding inwards and stalling the turn.

The roller bearings were removed from the original hubs and installed in new aluminum hubs. Steel rings were rolled, machined, and press fitted to solid rubber forklift style tires after bolt circles were welded inside.

Three point turns are now a snap, and no further risk of flat tires during a show.
