The development of gears for high-performance robotics, both terrestrial and planetary, has long been driven by design, the performance of lubricated steel gears, and the precise manufacturing of the gear components. Complex gear designs required in many robotics applications make up the majority cost of the robot, owing to the intricate manufacturing of steel. For space applications, the problem is compounded by extremely low temperatures, which preclude most lubricants. NASA JPL has been developing a unique class of BMG gearboxes for robotics using cutting edge technology for both the alloys and the manufacturing. This talk focuses on the need for low-cost, high-performance gearboxes and will give a status report of the research, including prototyping, alloy development, and testing. We show that BMGs not only have the potential for use as unlubricated gearboxes for space applications, but also as a revolutionary material for decreasing the manufacturing cost of all humanoid robotics.
