chain v. direct
We're going with chain giving 4X4 drive, but we've shied away from casters added to direct drive systems from some unsavory problems our rookie year. if anyone was at the Columbia regional two years ago, they remember a big gold triangle that couldn't go up the teeter totter, and was beaten by a robot that couldn't move. the reason, aside from bad gearing, was the casters caused the robot to spin wildly, as it changed from turning to going strait. the casters would spin into position moving the robot in the process. also in the same fashion as a shopping cart, if one wheel came off the ground and spun, then hits the ground again, the robot will swerve in that direction, and if a caster gets stuck, the robot will spin in large circles!
My advice: stay AWAY from casters! they are evil!
