MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621040771 A) filed by Sage University, Indore, Madhya Pradesh, on March 31, for 'apparatus for safety-critical autonomous navigation in warehouse environment.'
Inventor(s) include Dr. Prashant Jain; Ms. Sakshi Agrawal; Dr. Ritu Tandon; and Prof. Snehlata Mishra.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to safety-critical autonomous navigation in warehouse environments. The apparatus (102) includes a sensor assembly (104) and a processing circuit (106) that fuses measurement data to generate a composite occupancy grid and computes a traversal path avoiding occupied cells. The processing circuit (106) transmits a periodic heartbeat signal to a hardware watchdog device 108. The hardware watchdog device 108 monitors the heartbeat signal and resets a timer upon each received signal. Upon timer expiry due to heartbeat absence, the hardware watchdog device (108) disconnects the processing circuit (106) from a motor drive interface (110) and connects a failover controller (112). The failover controller (112) receives distance measurements from ultrasonic transducers (114) distributed around the apparatus (102) perimeter. When a distance measurement falls within a predetermined safety threshold, the failover controller (112) commands-controlled deceleration of the apparatus (102) to zero velocity, ensuring fail-safe operation."
