Disclosed are systems and methods for reproducing a body motion via a network, and systems, devices and methods for identifying a body motion. In an embodiment, the system for reproducing a body motion via a network comprises a sensor configured to capture a surface electromyography signal generated by a body motion of a user at a first terminal in the network a processor configured to receive the signal from the sensor and identify the body motion based on the received signal, and send information associated with the body motion to a second terminal in the network, the processor being located in the first terminal and a mechanical member configured to receive the information associated with the body motion from the second terminal and reproduce the body motion based on the received information.
