Abstract: A manipulator according to an embodiment may comprise: a housing; a rotary unit which is disposed in the housing and has a first rotating shaft; and a linear unit at least a part of which is disposed in the housing and which performs linear motion with respect to a breaker, wherein one side of the linear unit may be connected to the breaker and the other side of the linear unit may be connected to a part of the rotary unit.

Abstract: A laser rangefinder, including: a housing; a first rotational mechanism, mounted to the housing, including a first shaft and a first driving device, the first driving device driving the first shaft to rotate about a first axial direction; a reflector, connected with the first shaft; a laser rangefinding module, mounted within the housing, including a transmitting module and a receiving module; a second rotational mechanism, mounted to the housing, including a second shaft and a second driving device, the second driving device driving the second shaft to rotate about a second axial direction, the first axial direction and the second axial direction being non-parallel; wherein the first shaft is configured to drive the reflector to rotate on a scan plane, the first rotational mechanism, the laser rangefinding module and the second rotational mechanism are located at a same side of the scan plane.

Abstract: This invention discloses primarily using a digital chip in a platform rather than a central processing unit, driver or application software to stitch digital image signals from image sensors, and then transform it into an image file for output, display or storage. The stitched and compressed image is much smaller in the size of data computation to attend a real-time image stitching effect in a better quality and smoothness of image.
