The system and method for efficient communication bus arbitration are a system and method for slave communication bus arbitration in multi-drop communication, and provide efficient and fast communication speed by improving the packet structure in a manner in which a slave controller sequentially responds to a query of a master controller.

Abstract: Proposed is an elastic body having variable rigidity, wherein the elastic body is used in a series elastic actuator module, connects an input and an output, and has a rigidity that varies according to the applied torque. The elastic body having variable rigidity comprises: a connection part which receives torque from the input side or the output side; and a spring part connected to and receiving torque from the one selected from among the input side and the output side which is different from the connection part, wherein the spring part is formed integrally with the connection part and has a rigidity that varies as the connection part and the spring part come into contact with each other due to deformation caused by the applied torque.

Abstract: The present invention relates to a load torque detection technology, and more particularly, to a device and method for load torque detection in a robot system. According to an embodiment of the present invention, it is possible to accurately detect the load torque without requiring a position sensor included in a load torque measurement actuator to have a multi-revolution function or additional power supply.
