Abstract
A mobile robotic device, a connector for connecting trailers in mobile robotic device and a method of controlling the device for yaw control and pitch control are provided. The connector includes: a first body; a second body connected to the first body and rotatable with respect to the first body about a first axis; a third body connected to the first body and rotatable with respect to the first body about a second axis; and a fourth body connected to the second body and rotatable with respect to the second body about a third axis, wherein the connector is switchable between a yaw control mode in which the second body is driven to rotate with respect to the first body in a horizontal plane and a pitch control mode in which the second body is driven to rotate with respect to the first body in a vertical plane.
