Abstract: An optical detecting device includes a multi-axis instruction outputting mechanism and an optical detecting module, and shift of the multi-axis instruction outputting mechanism is determined accordingly. An actuating component of the multi-axis instruction outputting mechanism is moved in reciprocation at a first operating direction to output an instruction. The optical detecting module is disposed by the actuating component. An interval between the optical detecting module and the actuating component is varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, and the actuating component can be shifted between different gears. The optical detecting module determines the interval and related gearshift according to variation of a reflecting signal actuated by the actuating component, and utilizes the reflecting signal to acquire a movement of a feature point on the actuating component along the first operating direction to interpret the instruction.

Abstract: There is provided a robot including a first light source, a second light source, an image sensor and a processor. The processor is used to calculate an image quality of an image frame captured by the image sensor when the second light source is being turned on. The processor then determines whether to switch the second light source back to the first light source according to the image quality to accordingly identify the material of an operation surface.

Abstract: An optical tracking device is used to track a target object. An outer surface of the target object is divided into a first region and a second region adjacent to each other, and a marker is disposed on the first region. The optical tracking device includes an optical sensor and an operation processor. The optical sensor has auto exposure function and is adapted to acquire a detection image containing at least one of the first region and the second region. The operation processor is electrically connected to the optical sensor and adapted to analyze variation of an exposure parameter of the auto exposure function for determining whether the first region is appeared in the detection image, so as to acquire an operation datum of the target object.

Abstract: An optical tracking device includes an optical detection module and a target component. The optical detection module includes an optical receiver. The target component includes a light penetrating body with at least one mark and movably disposed adjacent to the optical detection module. The target component allows an illumination beam penetrating into the light penetrating body, so that the optical detection module acquires a detection image containing a pattern of the mark for tracking a relative movement between the target component and the optical detection module.

Abstract: A game board device is provided for carrying and identifying game pieces that are divided into different piece types. The game board device includes a board, a plurality of optically identifying modules, and a processing module electrically coupled to the optically identifying modules. The optically identifying modules respectively correspond in position to detection regions of the board. Each of the optically identifying modules includes a light emitter that can emit light toward the corresponding detection region and a light receiver that can receive light reflected by the corresponding detection region. When any one of the detection regions is in an unoccupied mode, the corresponding optically identifying module can emit an unoccupied signal. When any one of the detection regions is in an occupied mode, the corresponding optically identifying module enables an identification signal that corresponds to the piece type of the corresponding game piece to be emitted therefrom.
