Wild Swerve Drive Modules

AndyMark is pleased to work with 221 Robotic Systems for the production of the Wild Swerve gearbox system. Based on designs perfected by Wildstang, FIRST Robotics Team 111, this swerve/crab module is a great solution for creating an omni-directional mobile robot.

This gearbox is shipped unassembled, in kit form. This kit does NOT include a motor, wheel or wheel hub. See accessories for recommended solutions.

This transmission is designed to interface with a CIM motor. It can also be used with an AM Planetary gearbox.

Gear Ratios

These modules are set up to have various overall reductions and speeds, estimated while using a 6" diameter wheel. This gearbox system can be assembled with many different standard ratios. When ordering a gearbox, pick the ratio that is best for your application. The ratios and associated speeds are listed in these gear ratios.

Here is a list of other gear ratio setups, and approximate speeds when using a 6" diameter wheel:

Wild Swerve Drive Module with 31.89:1 ratio, at 2.3 feet/second

Wild Swerve Drive Module with 21.15:1 ratio, at 3.4 feet/second

Wild Swerve Drive Module with 14.88:1 ratio, at 4.8 feet/second

Wild Swerve Drive Module with 9.87:1 ratio, at 7.3 feet/second

Wild Swerve Drive Module with 6.94:1 ratio, at 10.4 feet/second

Wild Swerve Drive Module with 5.36:1 ratio, at 13.4 feet/second

Wild Swerve Drive Module with 3.55:1 ratio, at 20.3 feet/second
