Hardware not included.
These chassis use a design similar to the ProtoBot chassis, including (2) bumpers and (4) rails. The flexibility and variety of design options makes these chassis great for any robot project.

Variable chassis width by mounting the rails inward.
Space between rails for protected chain or gear reduction.
Extra "fifth hole" in the center of four holes adds additional flexibility.
Wheels may be mounted outboard or between the rails.
Bumpers may be mounted up-side-down for more flexible designs.
The "Super" chassis is taller with more vertical mounting locations.
