Abstract: A wearable walking assist robot is provided that ensures high walking assistance performance without a complex calculation process by detecting a gait phase based on pressure distribution on feet and performing a corresponding control mode that is set in advance. The wearable walking assist robot includes a sensor unit that senses pressure on the soles of the feet of a wearer and a controller that determines gait phases of both a first leg to be operated and a second leg based on the sensed pressure. Additionally, the controller selects one of a plurality of control modes set in advance based on the determined gait phases and operates a joint-driving unit for the first leg to be operated.

Abstract: A one-touch coupling/decoupling apparatus for a robot foot includes: a work shoe having a coupler protruding downwardly from a bottom of the work shoe; and a robot foot module coupled to the work shoe and having latches, each of which has one end formed in a hook shape so as to be coupled with the coupler.

Abstract: A method for controlling a wearable robot includes deducing a knee joint angle value of a robot using a joint angle sensor in a control unit, comparing the deduced knee joint angle value with a reference knee joint angle value previously stored in the control unit, deducing a thigh angle value using a thigh angle sensor in the control unit when the deduced knee joint angle value exceeds the reference knee joint angle value, comparing the deduced thigh angle value with a reference thigh angle value previously stored in the control unit, and setting an operation mode of the robot to a lift-up mode in the control unit when the thigh angle value exceeds the reference thigh angle value.

Abstract: The present invention relates to a braille input and output device which recognizes a normal word transmitted from the outside as braille by a tactile sense of a person and converts a braille input through an input key assembly into a normal word to wirely or wirelessly transmit the normal word. According to the present invention, the braille input through the input key assembly is reversely translated into the normal word or the normal word which is transmitted from a wirelessly connected external apparatus is translated into braille so that information which is input as the braille is translated into the normal word to be transmitted to the external apparatus.

Abstract: A safety damper includes a cylinder having a circular cross-section and a piston shaped as a disk having a predetermined thickness. The piston is inserted into the cylinder and has a through-hole. A safety plate is shaped as a disk having a predetermined thickness, is spaced a predetermined distance from and coupled with the piston, and has a hole corresponding to the through-hole of the piston. A piston rod extends through and is coupled with the piston and the safety plate. An elastic member is provided between the piston and the safety plate.
