Caption: This video shows how the SMART surgical tool is able to "hold still" by responding to unexpected movement from a surgical target (in this case, a chicken embryo). In the first part of the clip, the surgical tip of the SMART device has a good response to the unexpected embryo movement to keep a constant height. And then it is more stable at the latter part of the clip without the target's movement.
