Transport robot and robot system

A transport robot that travels autonomously, the transport robot comprising:

• a traveling mechanism that causes the transport robot to travel;
• an obstacle sensor that has a two-dimensional detection region along a direction of travel, and that detects a surrounding obstacle;
• a human detection unit that has a three-dimensional detection region extending around the transport robot, and that detects a surrounding person;
• and
• a controller that controls the traveling mechanism to cause the transport robot to travel autonomously to a predetermined work area, and that controls the traveling mechanism to cause the transport robot to decelerate or stop when an obstacle is detected by the obstacle sensor while the transport robot is traveling autonomously or when a person is detected by the human detection unit while the transport robot is traveling autonomously.
