1. A method for controlling operation of a robotic device, the method comprising: receiving, by a robotic device, a first signal from a positioning hardware device that is worn by a user, wherein the first signal describes a first relative location between the user and the robotic device, wherein the first relative location comprises a distance and direction between the user and the robotic device; receiving, by the robotic device, a second signal from the positioning hardware device that is worn by the user, wherein the second signal indicates that the user is pointing at a user-selected object, wherein the second signal comprises a description of a horizontal angle formed by a first line between the user and the robotic device and a second line between the user and the user-selected object while the user is pointing at the user-selected object, and wherein the second signal further comprises a description of a vertical spatial inclination of the positioning hardware device while the user is pointing at the user-selected object; determining, by one or more processors, an identification and location of the user-selected object based on the first signal, the second signal, and a record of object positions of objects within a predefined area of the user; determining, by one or more processors, a direction and distance from the robotic device to the user-selected object, wherein the direction and distance from the robotic device to the user-selected object is derived from the first signal, the second signal, and the record of object positions of objects within a predefined area of the user; determining, by one or more processors, whether the robotic device is authorized to perform a specific task on the user-selected object; and in response to determining that the robotic device is authorized to perform the specific task on the user-selected object, traversing, by the robotic device, the direction and distance from the robotic device to the user-selected object and performing, by the robotic device, the specific task on the user-selected object.
