Abstract: The present disclosure relates to an array antenna including at least: a power supply unit; a power supply line consecutively bent in the longitudinal direction, and connected to the power supply unit; and a plurality of radiation devices consecutively arranged to be spaced apart from each other in the longitudinal direction of the power supply line. The present disclosure also relates to a radar system for vehicles having an array antenna, including at least: a power supply unit; a power supply line extended to have a predetermined length; a plurality of radiation devices consecutively arranged in the longitudinal direction of the power supply line, and installed to be slanted with respect to the longitudinal central axis line of the power supply line in order to have directivity in the polarized direction; and a controller detecting objects near a vehicle by using the transmitted and received signals.

Abstract: Disclosed herein are a tube continuum robot and a method for manufacturing a tube. More particularly, disclosed are a tube continuum robot and a method for manufacturing a tube, which is used in the tube continuum robot having a plurality of overlapping tubes and has anisotropic patterns for controlling the bending rigidity and torsional rigidity of the tube. In an embodiment, a tube continuum robot has a plurality of overlapping tubes, one or more of the plurality of overlapping tubes having a curved shape, wherein a plurality of anisotropic patterns are formed on the outer circumferential surface of the one or more tubes along the lengthwise or circumferential direction of the tubes.
