Gabe came the closest... we lift up our robot completely off the ground in order to achieve low gearing, and high torque.... this is how it works.... We create 290lbs. of torque because of an all student designed drive train that instead of using a two speed transmission uses a custom working trans. like this... In high speed (Low Torque) two big diameter small width wheels on the ground and two scrubber wheels.... In low speed (High Torque) Four wheels with a smaller diameter and larger width come slamming to the ground to lift the entire robot and speed wheels off the ground to create an amazing amount of force on the opposing object (shall i say robot) we have found that if we put our 2006 bot sideways we can push it with amazing ease.

And also... yes we have seen this before, but we have never seen it carried out to this caliber... This idea may have been used before, but we think that so far this will be one of the most powerful ways of creating this design. This design was mainly based off the question of how can we make a high torque, high speed, and 0 turn robot. After lots of deliberation we finally found our answer. Also like I had said before this drive train works great, and it is like a tank without the treads, loss of speed, and slower turning capabilities...

Are there supposed to be two more of the large wheels in the picture?

[robostangs548]

Nope.... it is has two large front wheels, and two scrubber wheels in the back, which act as a lighter version of two more drive wheels, and also add a zero turning capability and low lag or (jitter) while turning the bot. If you look at the next picture it will show you what the bot currently looks like, and will help you better understand the drive trains intentions.
