Abstract: A pressure detection device of detecting a forced state of a deformable object includes a body, an image sensor and a processor. The body is a deformable hollow structure. The body has an inner surface and an outer surface, and an identifiable vision feature is disposed on the inner surface. The image sensor is disposed inside the body and faces the inner surface of the body, and is adapted to capture a frame containing the identifiable vision feature on the inner surface. The processor is electrically connected with the image sensor, and adapted to analyze position variation of the identifiable vision feature within the captured frame for identifying a motion type of a gesture applied to the outer surface of the body.

Abstract: There is provided a cleaning robot system including a charging station and a cleaning robot. The charging station includes multiple positioning beacons. The cleaning robot includes an image sensor and a processor. The image sensor is used to acquire light generated by the multiple positioning beacons on the charging station and generate an image frame. The processor is electrically connected to the image sensor, and used to calculate a relative position with respect to the charging station according to beacon images of the multiple positioning beacons in the image frame to determine a recharge path accordingly.

Abstract: A joystick includes a first structural component, a second structural component, a light emitter, an optical sensor and a processor. The second structural component is assembled with the first structural component to form a chamber. The light emitter is disposed inside the chamber for illuminating one surface of the second structural component. The optical sensor is disposed inside the chamber for capturing the illuminated surface of the second structural component. The processor is electrically connected to the optical sensor and adapted to analyze an intensity distribution of the illuminated surface for determining if the joystick is obliquely pressed or laterally shifted in a relative manner.
