This is a small but powerful drive base chassis for practice or off-season projects.

• Description
• Specifications
• Documentation

• The Rover Chassis is the newest addition to our AndyMark family of drive bases. The Rover was inspired by our 2019 Launch Bot. This small yet powerful drive base is perfect for that off-season project you'll be wanting to tackle. Rover is available in two configurations: 8 in. Pneumatic Wheels or 6 in. SR Mecanum wheels. Each configuration has been optimized for speed and power and features AndyMark RedLine Motors and 57 Sport Gearboxes. The chassis dimensions are approximately 22 in. x 18 in. x 6 in. but vary slightly depending on the version.

  Gear Ratios

  Each version of Rover has been optimized for speed and power. The 8 in. Pneumatic Wheel configuration features a pair of Sport Two Motor Gearboxes while the 6 in. Mecanum Wheel configuration utilizes four 57 Sport Gearboxes.

  • 8 in. Pneumatic Chassis: 52:1 overall reduction, 14.11 ft/sec unadjusted free speed
  • 6 in. Mecanum Chassis: 64:1 overall reduction, 8.60 ft/sec unadjusted free speed
