The patent describes an autonomous mobile robot with an upper module for cargo and a lower driving module featuring multiple pairs of wheels that can asynchronously contact the ground to overcome steps or stairs. It includes sensors for obstacle detection and is designed for indoor/outdoor logistics, guidance, and security tasks without predefined paths.
Claims
An autonomous mobile robot comprising an upper module with cargo space and cover; a lower module providing driving force; a driving module with plural pairs of wheels capable of asynchronously contacting road surface to overcome steps/stairs; and a control unit managing the driving module operations.
Technical analysis
The core innovation lies in the modular driving system allowing independent wheel pair actuation for enhanced mobility over uneven terrain like stairs, combined with omnidirectional sensing (cameras, IR sensors) for autonomous navigation. This addresses limitations in traditional wheeled robots by enabling variable ground contact without complex legged mechanisms.
Commercial impact
Enables versatile service robots for logistics and delivery in varied environments, potentially reducing costs in warehousing, airports, and urban delivery by improving reliability over obstacles. Assignee Robotis specializes in robotics components, suggesting integration potential with existing platforms.
