Abstract: Disclosed is a flexible tactile actuator including a tactile transmitter configured to be flexible and including magnetic particles capable of being polarized in response to an external magnetic field and a matrix layer including the magnetic particles, a magnetic field generator disposed below the tactile transmitter and configured to generate a magnetic field in the tactile transmitter, and an elastic member provided in a shape of a film, having at least a portion in surface contact with the magnetic field generator, and attached to be in surface contact with one of a top surface and a bottom surface of the tactile transmitter.

Abstract: A cycloidal reducer includes a reduction unit configured to reduce a torque input and an output unit configured to transfer the reduced output to the outside. A cycloidal rotor that is one constituent element of the reduction unit has a tooth-type protrusion formed in the shape of a circular arc. Thus, the level of difficulty of process is decreased more than when the tooth-type protrusion in the related art is formed in the shape of a broken line. In addition, rotor pins are accommodated in through-holes, respectively, that are equally spaced in the cycloidal rotor. A bushing is formed that fills a gap between the through-hole and the rotor pin is formed in order for the rotor pin to stably transfer rotational power. Accordingly, the advantage of effectively distributing a load and stably transferring a reduction torque to the outside is provided.

Abstract: A reducer includes a reduction unit configured to reduce an input torque, and an output unit configured to be supplied with a preset reduction torque through the reduction unit and to transfer an output torque to the outside. The reduction unit includes an input shaft configured to be supplied with the input torque, a cycloidal disc arranged on an outer circumferential surface of the input shaft in an eccentrically rotatable manner, a tooth-type protrusion being formed along a circumference of an edge of the cycloidal disc, a hollow housing configured to accommodate the cycloidal disc and including a plurality of inner pins arranged to be spaced a predetermined distance apart from each other along a circumference of an inner circumferential surface of the hollow housing in a manner that possibly comes into contact with the tooth-type protrusion on the cycloidal disc, and a plurality of rolling pins coupled to the cycloidal disc and having a cylindrical structure.

Abstract: The present disclosure relates to a cycloidal reducer. The cycloidal reducer according to the present disclosure includes a reduction unit configured to reduce a torque input and an output unit configured to transfer the reduced output to the outside. A cycloidal rotor that is one constituent element of the reduction unit has a tooth-type protrusion formed in the shape of a circular arc. Thus, the level of difficulty of process is decreased more than when the tooth-type protrusion in the related art is formed in the shape of a broken line. Accordingly, the advantage of increasing the productivity is provided. In addition, rotor pins are accommodated in through-holes, respectively, that are equally spaced in the cycloidal rotor. A busing is formed that fills a gap between the through-hole and the rotor pin is formed in order for the rotor pin to stably transfer rotational power. Accordingly, the advantage of effectively distributing a load and stably transferring a reduction torque to the outside is provided.
