Path Planning Reflecting the Changing Working Environment Through the Cargo Load Placement and Retrieval by Omnidirectional Transporter and Radio Frequency Identification

Abstract

The warehouse transport environment changes with load movement, e.g., the area where a load is placed becomes an obstacle for a carrier and the area from which a load is removed becomes area once more useable for movement. These considerations make path planning an important aspect of work planning. Transport system is suggested to manage environment change using radio frequency identification (RFID) which is put on a load and records the data of load size and its position. When the environment data of RFID changes by placing or removing the load, new information is read by reader of load carrier and sent to map management server. A three-omnidirectional vehicle is used to make transport more efficient.
