About

P.M. Beckham’s research lies at the intersection of robotics, mechatronics, and precision actuation, with a particular focus on solid-state ultrasonic motor technology. His most cited work, “Exploiting solid state ultrasonic motors for robotics” (2003, 14 citations), introduces a compact parallel jaw gripper driven by a resonant ultrasonic motor—a design that achieves 10 oz of linear force while maintaining a static holding force exceeding 10 oz in the power-off state, thanks to high-friction natural properties. This contribution is notable for advancing the use of ultrasonic motors in robotic applications, offering advantages like silent operation, high torque at low speeds, and inherent braking without power. Beckham’s work demonstrates how solid-state actuation can enhance robotic dexterity and safety, particularly in lightweight or space-constrained systems. While his citation count reflects a focused, niche impact, his innovations resonate in fields requiring precise, low-power motion control. Beckham’s achievements underscore a career dedicated to bridging fundamental motor physics with practical robotic design, inspiring further exploration into non-traditional actuators for next-generation automation.
