To provide a method by which an actuator mounted on a traction truck is driven and controlled while an increase of a total weight of the traction truck is suppressed as low as possible in an unmanned transportation system with an unmanned carrier and a traction truck attracted by the unmanned carrier.SOLUTION: An unmanned carrier 10 has a power storage part 21, traction drive sources 19, 20 driven by power stored by the power storage part 21 to drive the wheels of the unmanned carrier 10, a traction control part 25 to control the drive of the traction drive sources 19, 20, a power supply part 28 to supply the stored power in the power storage part 21 to the traction truck 50 and a power supply control part 26 to control electric power supply by the power supply part 28. The traction truck 50 has a power incoming part 63 to receive power from the power supply part 28 built in the unmanned carrier 10 and an actuator 75 driven by power received from the power incoming part 63 and the power supply control part 26 controls working of the actuator 75 by controlling the power supply to the power incoming part 63 built in the traction truck 50 from the power supply control part 28.SELECTED DRAWING: Figure 3 【課題】無人搬送車と、該無人搬送車によって牽引される被牽引台車とを備えた無人搬送システムにおいて、被牽引台車の総重量の増加を極力抑制しながら被牽引台車に搭載したアクチュエータを駆動制御できるようにする。【解決手段】無人搬送車１０は、蓄電部２１と、該蓄電部２１に蓄電された電力により駆動され、該無人搬送車１０の車輪を駆動する走行駆動源１９，２０と、該走行駆動源１９，２０の駆動を制御する走行制御部２５と、前記蓄電部２１に蓄電された電力を被牽引台車５０に向けて供給する給電部２８と、該給電部２８による給電を制御する給電制御部２６とを有し、前記被牽引台車５０は、無人搬送車１０に設けられた前記給電部２８からの電力を受電する受電部６３と、該受電部６３にて受電した電力により駆動されるアクチュエータ７５とを有し、給電制御部２６は、給電部２８から被牽引台車５０に設けられた受電部６３への給電を制御することでアクチュエータ７５の作動を制御するように構成されている。【選択図】図３
