Light as a Feather
Robot-guided needles can perform delicate tasks such as eye surgery. This video shows how sensitive such needles are to just the touch of a feather.

Robot "Feeling"
When using a robot, surgeons can't directly feel the force they're applying. So researchers at Johns Hopkins are trying out different means of audio and tactile feedback for the surgeons using eye surgery robots.

A Steady Hand
The robotic manipulator is specially designed for surgery on the retina, which requires very delicate movements and steady hands. Here, using a chicken embryo to stand in for a human retina, you can see the advantage of using a robot. First, video of a surgeon inserting the needle by hand, and second, footage of a robot-assisted needle.
