The system guides itself using 3-d ultrasound imaging as its eyes, and has shown it can accurately guide two needle probes through tissue in a simulated biopsy and blood vessel graft. The bot's still in its experimental phase, but ultrasound specialist Stephen Smith and his research team believe the day is near when robots will autonomously conduct surgery without the need for human guidance.
