The Tonka toy dozer has some pretty tough tracks on it, but you
would have to make the wheels. The ones on the toy are made of
plastic too thin to attach a drive mechanism to. There may be a
better solution, however. There are two options I think might work:
1. Conveyor belt manufacturers are increasingly going towards making
them out of small 'track like' sections. Each section is made out of
plastic and attaches in the center to the drive mechanism, usually a
chain drive. The sections also connect together. Some of the narrower
ones (for small conveyor belts) might work nicely. One disadvantage
is that the sections are extremely smooth (on top) and would need
some type of tread glued on (the bottom in our application). Again,
you would have to make the wheels. The conveyor parts would have to
be for a linear conveyor, the sections designed for curving are (you
guessed it)... curved, and wouldn't work for a robot track.
2. Recently I've seen a type of plastic cable guide system that uses
linked sections that are hollow on the inside. The stuff I've seen
snaps together and only bends one way. It's used on large repetitive
motion machines, like CNC machining centers where driver wires don't
move very far but do move back and forth alot. I'm not describing
this product well, but it's basically an articulating 'box' that
houses the wires. This stuff is made of tough, thick plastic that
would hold up well. Again, you would have to come up with a wheel
design...
Hope this helps, Duncan

| Other than using Lego or fischertechnik tracks (about equal in durability) the only option I could come up with is (are) the radio control tanks made by Tamiya.
