More particularly, an obstruction-determining apparatus which can determine whether a mobile robot is obstructed in a niche, and enable a mobile robot to easily escape from an obstacle if the mobile robot is determined to be obstructed in the niche, and a boundary-estimation method and medium for estimating the boundaries of an obstacle with a niche using the obstruction-determining apparatus. The obstruction-determining apparatus includes a contact module which collides with an obstacle above the mobile robot, a contact-operating module which rotates or moves linearly as a result of the collision between the contact module and the obstacle, and a sensing module which detects the rotation or the linear movement of the contact-operating module and determines whether the mobile robot is obstructed in a niche."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Obstruction-determining apparatus for preventing mobile robot from becoming obstructed and boundary-estimation method and medium using the obstruction-determining apparatus","description":"An obstruction-determining apparatus for preventing a mobile robot from being obstructed in a niche and a boundary-estimation method and medium using the obstruction-determining apparatus are disclose","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8521329","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
