tank tracks

Lutamos

I bought the add on tracks for the BOE bot and the tracks were not that tight thus falling off when it tried to turn on carpet. I was looking for some other track chassis and I found this http://store.servomagazine.com/product.php?productid=16758&cat=384&page=2 but I saw it had the same tracks as that add on I bought. So before I plunk down 60ish dollars for this and find the same problem, Has anyone used this chassis ? How well it works?


Thank, you

See this page in the documentation, towards the bottom there are some suggestions, perhaps it will help.

I found that if I put one of the small wheels on the back and above the tread, that it tensions the belt a little bit more. Better than before. See the pictures here.

Ok thank you I wish I hadn't thrown the others away from frustration. That was a bad day and the tracks didn't make it better lol.

The tracks on that kit seem to be a normal set of Tamiya track and wheel set with some custom chassis work... although the chassis does look nice.

You can get the Tamiya track set for under $10 from many sites, and some of the same expanded PVC for around $6 a square foot at a few sites... the problem would be building your
own chassis.

I bought a simple kit that has the Tamiya track kit mounted on a piece of wood and includes a battery box and gearbox + motor. I had to replace the gearbox with a dual-gearbox
to get the kit to do more than go forward and reverse, but otherwise I have no complaints besides the tracks being too close together to put a Boebot frame between.

The kit was $14.99

Parallax actually has a fairly decent track kit that you most likely shouldn't overlook. It's designed to mount on the boebot frame and seems quite well made.
