About

Andrew Hoff is a leading figure in the development of advanced materials for high-performance robotics, with his work bridging the gap between materials science and mechanical engineering. His primary research focuses on bulk metallic glasses (BMGs) and their application in precision mechanical systems. Hoff’s most notable contribution is his pioneering demonstration of using BMGs as the flexspline in strain wave gears (also known as harmonic drives), a critical component in ultra-precision gearboxes. His 2016 paper on this topic, which has garnered 85 citations, showed that these castable, high-strength materials could significantly reduce the cost and complexity of manufacturing these gears while maintaining exceptional performance. This work directly addresses a key bottleneck in robotics: the high cost of precision actuation. By proving that BMGs can withstand the cyclic elastic deformation required for harmonic drives, Hoff has opened a new pathway for more affordable, high-torque robotic joints. His research is widely recognized for its practical impact, offering a tangible solution for making advanced robotics more accessible across industries from manufacturing to prosthetics.
