[J Flex 188]

haha.. casters are a big big pain.. well this year especially.. if you had 4 casters and were a stacker.. going up the ramp in front of a low profile robot was suicide.. honestly.. i even saw some KOH bots with casters not being able to make it up the ramp consistently... but tank treads are a neat idea.. creative ways to solve the turning issue too.. i believe one of the rookie teams (1000?) at West MI had a neat pneumatic lifter that would lift the front of the robot out, lowering the back end where there were 2 wheels on either side, allowing for quick turnarounds..


but overall, this year its been a good drivetrain (doesnt have to shift either) and a design that lets you do one thing in particular, really really well. blizz4d could push bins and robots around well, but an added bonus was a simple 2 stacker that came naturally with the design of the wings..
