What are the implications of autonomy?   At the Hamlyn symposium we discussed how medical robot autonomy may result in situations where the human operator may no longer mitigate risks.  There exists a shift in responsibility during robotic surgery--who becomes responsible for the outcome during robotic surgery?   What is the criteria for a surgeon's responsibility--control, regulation, intervention and/or observation?   Is the robot responsible?  Perhaps only if the robot is an agent.  What about the responsibility of the developer or manufacturer of the robot--collective responsibility?   What about a "responsibility gap" whereby no one is responsible?   What is our moral and legal respponsibility with new technologies?
