A transport system transports a transport object in a state sandwiching the transport object between a plurality of transport robots, wherein the transport robot comprises: a main body; wheels; a rotation mechanism that makes a contact part rotatable relative to the main body; a drive part(s) mounted on the main body and driving the wheels; a load sensor detecting a load when the contact part contacts the transport object; and an angle sensor that detects a rotation angle of the contact part relative to the main body, wherein using hardware resources, processings are executed to control the drive part so that load and rotation angle approach a first target value and a second target value based on information of a load and a rotation angle detected by the load sensor and the angle sensor.
