Figure AI Inc. recently secured a major technological breakthrough with the issuance of U.S. Patent No. 12722306. This patent, titled ‘End effector of a humanoid robot’, introduces a sophisticated tactile sensor assembly designed to enhance robotic dexterity and precision. Inventors Keith Wakeham, Michael Stevens, and Jake Goldsmith developed this advanced system to address longstanding tactile feedback limitations in humanoid robotics.
Innovative Tactile Sensing Architecture
The innovation centers around a unique bridge configuration within the tactile sensor assembly. Specifically, the bridge comprises a base section and three flexure arms, where each arm features a sloped section extending from the base at a first non-zero angle and a load section extending at a second non-zero angle. Strain gauges coupled to the sloped sections work in tandem with an internal electronics assembly to process incoming data. This geometric design allows the end effector to accurately measure and interpret contact forces and external pressures with high resolution.
Recognition for October 2026 Patent of the Month
This breakthrough earned the patent of the month award for the robotics computer engineering industry in October 2026 due to its engineering ingenuity. Traditional robotic hands often struggle with delicate manipulation because they lack nuanced tactile feedback or reliable overload protection. This patented design solves these challenges by combining multi axis strain measurement with structural compliance and physical hard stops. The architecture prevents sensor overloading while enabling fine force resolution, representing a notable leap forward in robotic dexterity.
Practical Applications and United States R&D Tax Credit Eligibility
Beyond its theoretical design, this patented technology holds strong potential for qualifying under United States research and development tax credit provisions. Companies engaging in the experimental development of advanced robotic hardware regularly incur eligible expenses under Section 41 of the Internal Revenue Code. Developing novel tactile sensor assemblies involves iterative prototyping, performance testing under various load conditions, and overcoming technological uncertainties related to sensor durability and signal processing accuracy. Because these activities aim to create functionally improved robotic manipulation systems with higher reliability, the engineering work required to bring U.S. Patent No. 12722306 to market supports substantial federal R&D tax credit claims.
