Robot Actuators

This is a collection of three different sized compound planetary gearboxes with compact form factors ideal for assembling into robot arms. All three sizes use 38.4:1 compound planetary gearing and include an integral slew bearing. The pancake configuration and convenient mounting surfaces make it easy to build your own robot arm by stacking the actuators a'la the UR3 or Sawyer industrial robots.The largest actuator (for arm base joints) is about 3.4" in diameter and uses 20 pitch helical gears.
