This system enables robots, particularly wheeled vehicles, to navigate complex environments autonomously and safely. It operates by evaluating a map of obstacles and a desired route, then uses pre-calculated movement options to find the best path. The system minimizes a cost function by applying a 'trajectory footprint mask' to the obstacle map, ensuring the robot avoids collisions in real-time.
Why it matters: Filed before significant advancements in AI-driven predictive models. Modern machine learning can now more effectively develop and optimize the 'black box forward model' for state inference and integrate diverse sensor data for mapping.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
