For transportatiQn in warehouse , an environment changes by placement and removal ofaload . A working area of placed the load becomes a new obstacle fbr a carrier . And a working area of removed the load becomes a removable area again . By considering the changing environment , it is thought that a path planning more emcient ls possible. 1n this paper , transport system is suggested by managing this changing environment with RFID which is stuck on a load , There arc data of size and position of the load in RFID . When the load is placed or removed , the envirQnment is 叩 dated by using the map management server which gets data of RFID through reader of the ca π ier. haddition, Three Orrmi − Directionaliehicle is used as a canier in order to carry out the effective transportation.
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.
