About

R.A. Rattner’s research centers on the intersection of robotics, precision actuation, and solid-state motor design, with a particular focus on exploiting ultrasonic motor technology for compact, high-force applications. Their most notable contribution is the development of a small parallel jaw gripper driven by a resonant structure ultrasonic motor, a breakthrough that demonstrated how solid-state motors could generate 10 ounces of linear force while maintaining a static holding force exceeding 10 ounces even when powered off—a critical advantage for energy-efficient robotics. This work, published in 2003, has garnered 14 citations, reflecting its foundational role in advancing ultrasonic motor integration into robotic systems. Rattner’s achievements highlight the practical potential of high-friction, power-off holding mechanisms, offering a pathway to safer, more reliable grippers for automation and prosthetics. Their research continues to inspire innovations in compact actuation, bridging the gap between theoretical motor physics and real-world robotic dexterity.
