An autonomous mobile robot capable of navigating indoor and outdoor environments, generating paths autonomously, and overcoming obstacles like stairs or steps using a driving module with multiple pairs of asynchronously contacting wheels. Includes upper cargo module and lower driving module controlled by a central unit, with sensors for obstacle detection and modular design for general-purpose tasks like logistics or security.
Claims
1. An autonomous mobile robot comprising: an upper module including a cargo space and a cover; a lower module positioned under the upper module and providing a driving force; a driving module provided in the lower module; and a control unit that controls an operation of the driving module, wherein the driving module includes a plurality of pairs of wheels capable of asynchronously contacting a road surface or ground so as to overcome steps or stairs. (Additional dependent claims cover sensor configurations, wheel mechanisms, indicator lights, and control methods for path generation and obstacle avoidance.)
Technical analysis
The patent focuses on a wheeled mobility system (Muscle pillar) enabling variable ground contact for stair/step traversal without complex legged mechanisms. Key innovation is asynchronous wheel pairs in the driving module, combined with omni-directional cameras, IR sensors, and modular upper/lower body for adaptability. CPC classifications emphasize manipulators and vehicle wheel arrangements. Builds on prior art for robust indoor/outdoor autonomy.
Commercial impact
Enables versatile service robots for logistics, delivery, security, and guidance in varied terrains, potentially reducing need for specialized hardware. Assignee Robotis (known for robotics components) positions this for scalable commercial deployment in warehouses, airports, or urban environments, with granted status (US11858570B2) indicating strong IP protection.
