The pillow blocks on the wheel shown have bolts going through them vertically, which screw into T-nuts in the slot in the chassis. By sliding the entire wheel assembly away from the center of the robot, the chain can be tensioned without a separate device.

this is the best pic we've got, but you can see the wheels are mounted on custom axel mounts. Later on the sprockets and chain were put on the wheels. The mounts can slide in the extrusion, and by attaching the chain and then sliding the mounts we can tighten or loosen it as we please.
