Build all terrain robots!

This kit contains over five feet of tank tread designed specifically for the VEX Robotics Design System. Use this tank tread to build robot tracks which can overcome tough terrain, or build a conveyor belt for scooping up objects.

  • Climb over obstacles.
  • Traverse tough terrain.
  • Drive through sandy or soft spongy surfaces.
  • Can be used for a robot conveyor belt.
  • Every section is a master link, create treads of any length.



Tank treads will enable your robot to explore much more demanding terrain than ordinary wheels. Tank treads distribute a vehicle’s weight more evenly than wheels, allowing your robot to move more easily in sand or on soft, spongy surfaces into which wheels would sink and bog down. This increased surface area also gives your robot more traction for hauling heavy loads up an incline. And because each link can grip the surface over which it’s traveling, a robot with tank treads can more easily climb obstacles or traverse crevasses in which wheels would get stuck.
