Title:
AUTONOMOUS TRAVEL DEVICE AND AUTONOMOUS TRAVEL METHOD
Document Type and Number:
Japanese Patent JP2023182385
Kind Code:
A
Abstract:
To provide an autonomous travel device which can easily travel along a determined route in a short time and can reduce a risk of being brought to standstill halfway on the route.SOLUTION: The autonomous travel device causes a mobile carriage 1 to autonomously travel through a plurality of waypoints p within a designated area A. When causing the mobile carriage 1 to autonomously travel to a waypoint pi, basically the autonomous travel device estimates a self-position of the mobile carriage 1, generates waypoint information b from preliminarily stored obstacle position information a1, designated area information a2, and final goal point information a3, calculates a travel route to the waypoint pi on the basis of the estimated self-position and the generated waypoint information b, and causes the mobile carriage 1 to travel to the waypoint pi along the travel route. In order to prevent the mobile carriage 1 from being brought to standstill during autonomous travel, the autonomous travel device performs abnormality processing of changing a waypoint p being a travel destination of the mobile carriage 1 when determining that the mobile carriage 1 being traveling is in such a stuck state that it cannot reach the waypoint pi.SELECTED DRAWING: Figure 4
