Abstract: The present disclosure relates to a robot teaching system, which moves a robot according to an external force applied from the outside so that the robot has a location and posture intended for teaching and then teaches a location and posture of the moved robot, and the robot teaching system comprises: an arm including a plurality of articular shafts and a plurality of links connected by the plurality of articular shafts; a plurality of strain gauges respectively coupled to frames of the plurality of links to measure a deformation value of the link that is deformed by the external force; and a calculating device configured to estimate the external force from the deformation value of the link obtained by the plurality of strain gauges, calculate a teaching force from the external force and move the robot by an operation corresponding to the teaching force.

Abstract: Disclosed is a disinfection robot capable of autonomous driving and recognition of a disinfection target. The disinfection robot includes: a recognition unit configured to generate recognition information by recognizing a surrounding environment of the disinfection robot; a movement unit configured to move a position of the disinfection robot; a light source unit configured to emit a light of a predetermined wavelength area for disinfection; an injection unit configured to inject a fluid for disinfection; and a control unit configured to move the disinfection robot through the movement unit based on the recognition information, wherein the control unit is configured to identify a disinfection target from the recognition information and control at least one of the light source unit and the injection unit to perform disinfection to at least one of the surrounding environment of the disinfection robot and the disinfection target.
