MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641091281 A) filed by Easwari Engineering College; and Srm Institute Of Science And Technology, Ramapuram Campus on July 27, 2026, for Retractable Claw Assembly For A Robotic Gripper With Internal Ring Gear Synchronized Actuation Mechanism (cat-Claw-Inspired Design).
Inventors include Mr. R. Jeremiah; Mr. Sanjay Moorthy. M; Mr. Prasannaganesh. V; and Dr. R. Tharmaraj.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: A retractable claw assembly for a robotic gripper comprises a claw housing having a concealment slot, at least one claw member pivotally mounted within the housing and carrying a pinion gear, and an internal annular ring gear rotatably supported in the housing and internally meshing with the pinion gear. A rotary actuator, coupled directly or indirectly to the ring gear, selectively rotates the ring gear to pivot the claw between a retracted concealed position and an extended gripping position. In a multi-digit embodiment, a common internal ring gear simultaneously meshes with the pinion gears of multiple claw members, enabling synchronized extension and retraction using a single actuator. Optional biasing elements, one-way clutches, and locking detents provide hybrid passive-active actuation and deployment. The assembly provides compact construction, high torque transmission, synchronized operation, protected claw concealment, improved durability, and manipulation for robotic systems applications.
