PROBLEM TO BE SOLVED: To provide an unmanned carrier capable of smoothly returning to a trail truck even when an emergency stop occurs.SOLUTION: The unmanned carrier includes: a pair of right and left drive wheels which are driven to rotate receiving a drive force from drive means; brake means 10 and 11 provided to at least one to right and left drive wheels for braking the drive wheels when being activated; detection means 7 for detecting deviation amount between a trail truck formed on a floor a vehicle body reference point and deviation direction; and control means 9 that, when the detection means 7 detects an increase of the deviation amount, controls the brake means 10 located at the outer side in a deviation direction to repeat turning ON/OFF to correct the travel direction; and when the detection means 7 detects a decrease of the deviation amount, controls the right and left brake means 11.
【課題】緊急停止時においても速やかに軌道線に復帰することが可能な無人搬送車を提供する。【解決手段】駆動手段から駆動力を受けて回転駆動される左右一対の駆動輪と、オンすることにより駆動輪の制動を行う少なくとも左右1つずつ設けられた制動手段10,11と、床面に設けられた軌道線と車体基準点とのずれ量及びずれ方向を検知する検知手段7と、検知手段7がずれ量の増大を検知したときは逸脱方向外側の制動手段10のオンオフを繰り返して進行方向の修正を行い、検知手段7がずれ量の減少を検知したとき左右の各制動手段11をオンさせる制御手段9とを有する。【選択図】図4
