MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202631002633 A) filed by Dr. Subir Kumar Das, Kolkata, West Bengal, on Jan. 9, for 'a hierarchical operative critical-structure based autonomous navigation and motion control system.'
Inventor(s) include Dr. Subir Kumar Das.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a hierarchical navigation system and method for autonomous mobile robots operating in environments containing obstacles. The system enables local path planning and obstacle avoidance without reliance on a pre-constructed global map, making it suitable for dynamic and partially known environments. Environment perception data representing obstacles and navigable space is obtained from one or more data sources, including real-time sensors or simulated environments. Based on the perception data, the system constructs operative critical structures representing navigationally relevant spatial features influencing feasible robot motion. Candidate navigation behaviours are generated and evaluated using operability criteria comprising safety constraints, progress toward a target, and motion smoothness. A hierarchical supervisory controller selects or adapts navigation modes based on the evaluation. The system generates smooth and bounded motion commands suitable for safe operation in proximity to humans, enabling reliable deployment in assistive and service robotic applications."
