Abstract: The present application relates to the field of instruments, and provides a guidable and growable instrument and a surgical robot system. The guidable and growable instrument includes: a growable tube comprising an inner layer, an outer layer, and a fluid cavity between the inner layer and the outer layer, the fluid cavity being configured to accommodate a fluid. The growable tube includes a turnable region at a distal end, the inner layer and the outer layer are connected and turnable in the turnable region, a guide is arranged in a channel surrounded by the inner layer of the growable tube, and the distal end of the guide is bendable to drive the growable tube to turn. The guidable and growable instrument can better adapt to a gradually narrowed bent and complex orifice so as to reduce or avoid touch and friction with the orifice.

Abstract: Disclosed are techniques for determining a motion state of a target object. In an aspect, an on-board computer of an ego vehicle detects the target object in one or more images, determines one or more first attributes of the target object based on measurements of the one or more images, determines one or more second attributes of the target object based on measurements of a map of a roadway on which the target object is travelling, and determines the motion state of the target object based on the one or more first attributes and the one or more second attributes of the target object.
