Tank style tracks for robots are still hard to come by these days. Most available kits on the market are small light weight designs and wouldn’t hold up for even a medium sized robot. During one of our many internet hunting excursions we came across a unique site called Backyard Armor that sells metal tank treads for scale model tanks. These treads might work well for people needing rugged treads for outdoor robots so we thought we would pass along the info. If anyone tries these out please drop us a note. Backyard Armor
Update: 12/6/2011 Unfortunatly, it looks like the site is gone and some internet low life has taken over the domain. Don’t try to visit the site. Popups and annoyance abound.
