MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621028790 A) filed by Institute Of Technology, Nirma University, Ahmedabad, Gujarat, on March 11, for 'dual-mode rover for autonomous navigation and multi-surface operation.'
Inventor(s) include Dr Dhaval B. Shah; Dr Absar M. Lakdawala; Dharmik Makim; Yashvi Tanwar; Vinit Tandel; Preya Parikh; and Harsh Trivedi.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "A six-wheeled rover (100) includes a chassis (110), a rocker-bogie suspension (200) with differential linkage (240), and wheels (301-303, 305-307). Four corner wheels (301,303,305,307) are independently steered by actuators (401-404) while middle wheels (302,306) are non-steerable. A control system (500) supports an autonomous mode and a teleoperation mode and switches from one to the other during motion without stopping. Sensor inputs from LiDAR (601), camera (602) and IMU (603) enable autonomous navigation and obstacle avoidance. A kinematic solver (510) computes feasible body motion and an instantaneous center of rotation using a least-squares and/or null-space solution of a 4 3 Jacobian based on steering angles. An energy-optimization module (520) minimizes active steering actuators by holding non-required actuators near 0 while enabling crab motion, diagonal translation, and zero-radius turns. A fault-tolerant steering manager (530) locks failed actuators at 0 and maintains controllable motion using three-wheel, diagonal two-wheel, or one-wheel steering."
