Semi-Tank Tread/Half Tank Treads

[Greg Needel]

i have seen this design before you can possibly find pictures of robots at www.firstrobotics.net

but i must ask what the point is....you would get the same affect as wheels with casters especally with the smaller base size this year. all you would be adding is complexity to your system

We are trying to find the best balance between turning and carpet grip(pushing power).

Well, the thing about treads is that they only apply force to the carpet where the pulley (wheel the drives the tread) is pushing the tread into the ground. In essence, a tread design with 4 pulleys total would have the same contact with the ground as a 4wd bot (given that wheel size and pulley size are equal). Of course, this topic has already been discussed in threads like http://www.chiefdelphi.com/forums/sh...ad.php?t=31438 . Hope that helps.
