Abstract
An autonomous mobile robot (AMR) for transferring a component part in a process line of a production factory may include, a sensor unit configured to detect an obstacle in a travel path, an interface unit configured to identify coordinates of a waypoint and set an accuracy zone having a circular area around the waypoint, an omni-directional waypoint generation unit configured to obtain the travel path in a curved line which is aligned to tangentially meet a tangent vector of the circular area, a driving unit configured to generate a driving torque for driving the AMR, and a controller electrically connected to the sensor unit, the interface unit, the omni-directional waypoint generation unit and the driving unit and configured to control the driving unit to move the AMR along the travel path toward the waypoint, and when a current position of the AMR enters an effective range of the accuracy zone, to move the AMR toward the destination point without further moving toward the waypoint.
