Method of controlling electronic devices

The present disclosure relates to a linear compressor and a refrigerator including the same. A linear compressor according to the spirit of the present disclosure includes a shell, a cylinder, a piston and a muffler. And the muffler includes a plurality of flow tubes extending in a flow direction of the refrigerant, and a plurality of through-holes passing through at least one of the plurality of flow tubes.

Linear compressor and refrigerator including same

A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape, a shell cover that covers both open ends of the shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a piston that reciprocates within the cylinder in an axial direction to compress the refrigerant within the compression space, a motor assembly including a motor that provides power to the piston and a stator cover that supports the motor, and resonant springs seated on the stator cover that support the piston to allow the piston to perform a resonant motion. The resonant springs may be circularly arranged at three points having a same interval around a center in an axial direction.

Linear compressor

Disclosed is a compressor including a vibration attenuating member that fixes a driving assembly to be spaced apart from an inner circumferential face of a shell and reduces vibration or noise generated in the driving assembly.

Compressor

Provided is a linear compressor. Provided is a linear compressor. The linear compressor includes a shell defining an internal space, a compressor body disposed in the internal space, and a passage guide disposed between the shell and the compressor body. The passage guide may include a first guide part extending along an inner surface of the shell in an axial direction and a second guide part extending from the first guide part to the compressor body in a radial direction.

A method for modeling a robot simplified for stable walking control of a bipedal robot provides a robot model that is simplified as a virtual pendulum model including a virtual body, two virtual legs connected to the body at a virtual pivot point (VPP) that is set at a position higher than the center of mass (CoM) of the body, and virtual feet connected to the two legs, respectively, to step on the ground. A ground reaction force, which acts on the two legs, acts towards the VPP, thereby providing a restoring moment with respect to the CoM such that stabilization of the posture of the body naturally occurs.
