Patent number: 11366481Abstract: A mobile body configured so that multiple mobile robots can travel along the same track in formation even when an obstacle is present on the travel path of the mobile robots, and a method of controlling the mobile body. This mobile body (100) includes: a map storage (6) that stores travel path information; and an intelligence processor (10) that recognizes whether or not an object in the periphery is a mobile body to be followed (101). When the object is the mobile body to be followed (101) and the mobile body to be followed (101) does not exist on a travel path (16) indicated by the travel path information, the intelligence processor (10) sets a position on the travel path (16) in which the mobile body to be followed (101) is projected, as a temporary destination (17).Type: GrantFiled: July 18, 2018Date of Patent: June 21, 2022Assignee: PANASONIC HOLDINGS CORPORATIONInventors: Duyhinh Nguyen, Hiroyuki Uematsu, Takeshi Ando
