Abstract
The present application relates to a method for robot control. The method includes: obtaining at least one parameter associated with a robot to be controlled by a controller; determining a first identity of the robot based on the at least one parameter; comparing the first identity with a pre-stored second identity; and in response to the first identity matching the second identity, controlling operations of the robot with the controller. The present application further discloses detection of a mismatch between the controller and the robot in an easy, safe and convenient way.
Claims11
A method for robot control, comprising:
- obtaining at least one parameter from at least one motor in response to a request from a controller, the at least one parameter associated with a characteristic of the at least one motor arranged in a robot to be controlled by a controller;
- determining a first identity of the robot based on the at least one parameter,
- wherein the first identity identifies the at least one motor arranged in the robot;
- comparing the first identity with a second identity,
- wherein the second identity is stored in the controller;
- determining an identity of the robot to be controlled by the controller from other robots based on the comparison,
- wherein the robot is distinguished from the other robots based on the at least one parameter associated with the at least one motor arranged in the robot;
- and
- in response to the first identity matching the second identity, controlling operations of the robot with the controller;
- wherein obtaining the at least one parameter comprises:
- sending at least one excitation signal to at least one motor of the robot from the controller,
- receiving at least one feedback signal that is provided by the at least one motor in response to the at least one excitation signal, and
- determining the at least one parameter based on the at least one feedback signal and the at least one excitation signal.
A robotic system, comprising:
- a robot comprising:
- at least one motor;
- and
- a controller attached to the robot and configured to:
- obtain at least one parameter from the at least one motor in response to a request from a controller, the at least one parameter associated with a characteristic of the at least one motor arranged in the robot to be controlled by the controller;
- determine a first identity of the robot based on the at least one parameter,
- wherein the first identity identified the at least one motor arranged in the robot;
- compare the first identity with a second identity,
- wherein the second identity is stored in the controller;
- determine an identity of the robot to be controlled by the controller from other robots based on the comparison,
- wherein the robot is distinguished from the other robots based on the at least one parameter associated with the at least one motor arranged in the robot;
- and
- in response to the first identity matching the second identity, control operations of the robot with the controller;
- wherein obtaining the at least one parameter comprises:
- sending at least one excitation signal to at least one motor of the robot from the controller,
- receiving at least one feedback signal that is provided by the at least one motor in response to the at least one excitation signal, and
- determining the at least one parameter based on the at least one feedback signal and the at least one excitation signal.
