Do you believe humanoid robots will become a standard part of your local workforce soon?

Allegro MicroSystems has launched a new portfolio of power and sensing integrated circuits designed for humanoid robotics. The components, which include the A81481 power management IC, are currently available for evaluation and sampling.

Why it matters

Humanoid robotics manufacturers face strict constraints on size, weight, and power, and these new components aim to optimize these metrics for high-torque systems. The release addresses the need for compact, efficient hardware to manage complex joint movements.

The A81481 power management IC measures 6 mm x 6 mm, integrating dual buck regulators and five low-dropout outputs to reduce system footprint by a reported 50%. The CT310 XtremeSense sensor maintains angular error below 0.30° in a 2 mm x 2 mm package.

The players

Allegro MicroSystems

A developer of power and sensing semiconductor solutions for industrial and automotive motion control.

Sarcomere Dynamics

A robotics firm developing high-dexterity robotic hands and grippers for human-like manipulation.

The details

The A81481 chip manages power by integrating multiple regulators onto a single silicon die, reducing the physical bill of materials. The inductive position sensors, specifically the A17802 and A17803 models, utilize on-chip compensation and filtering to mitigate mechanical air-gap variations. These variations typically degrade performance in high-torque robotic joints, where electromagnetic interference can disrupt standard Hall-effect sensors.

The Tech Race

This release marks a shift toward specialized silicon for human-scale robotics, moving away from repurposed industrial motor control components. It specifically supports the development of the 24-DoF ARTUS Dex robotic hand by Sarcomere Dynamics.

Robotics engineers and developers can access samples of these integrated circuits immediately for evaluation in current prototypes. These components will eventually impact the efficiency and dexterity of next-generation humanoid platforms as they move into testing phases.

The takeaway

The industry is trending toward higher-voltage, smaller-form-factor power systems to improve humanoid mobility. Watch for the integration results of the 24-DoF ARTUS Dex hand to see if these components achieve the claimed 50% footprint reduction in real-world environments.
