Chassis Kits (4-sizes)

VEX Robotics chassis kits are larger versions of the VEX standard kit chassis. Mix and match to make a total of 16 different chassis sizes.

  • Four sizes available: 15x16, 25x25, 35x35, and 35x35 super.
    • Note: Chassis sizes are listed by number of VEX holes, (i.e. a 15x25 chassis is 15-holes wide x 25-holes long).
  • The Rails and Angles are also available individually.
  • 100% VEX Robotics compatible.
  • 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.
