Title:

UNMANNED CARRIER

Document Type and Number:

Japanese Patent JPH1165654

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To ensure realtime performance, algorithmic simplicity, and functionality extension simplification, with respect to an unmanned carrier traveling along a guide path. SOLUTION: This carrier is provided with a guiding FSM(finite state machine) 28 for performing operation of reducing position deflection with respect to a guide path at the time of detecting the guide path, avoiding an FSM 27 for performing an operation for avoiding an obstacle at the time of detecting the obstacle, a storing action FSM 29 for storing the evading of the obstacle and performing an operation in a direction opposite to the operation performed for avoiding the obstacle, and an attitude correcting FSM 30 for performing an operation for reducing an attitude angular deflection around a vertical shaft against the guide path during guide path withdrawal. The priority order is set in the order of the escaping FSM 27, the guiding FSM 28, the storing action FSM 29, and the attitude correcting FSM 30, and at the time of an operation by an FSM whose priority order is higher, the operation by an FSM whose priority order is lower is suppressed.
