White Paper Overview

As robotic systems become more powerful and precise, actuator design is facing new challenges around power density, thermal management, motion accuracy, and space optimization. Emerging trends such as 48V power architectures, in-line current sensing, and dual high-resolution position sensing are enabling the next generation of robotic joints, but they also introduce new design considerations.

In this whitepaper, Allegro MicroSystems examines the technologies and architectural choices shaping modern robotic actuator development. Learn how advances in gate drivers, current sensing, and position feedback can work together to increase torque density, reduce heat generation, maximize PCB space, and improve motion control performance.

Whether you’re designing humanoid robots, autonomous mobile robots (AMRs), robotic arms, or industrial automation systems, this guide provides practical insights to help you build more efficient, reliable, and high-performance robotic actuators.
