Generally, the superstructure is what things get attached to, it can be pemanently attached via welding, temporarily attached through rivets (use steel), or Bolted on with nuts and bolts. As posted above, the superstructure can even be made removable for easy changes to the drive base.

One small suggestion, have you thought about 3Cim gearboxes? They are an easy way to increase the torque available on your robot and make it generally faster.

Awesome to see more Oregon Teams on CD, good luck!
