Robots could be about to become a more important part of healthcare, due to advances in technology relating to sensors.
This is according to Mike Wilson, director of the British Automation Robotics Association, who pointed out that robots are already playing a part in various aspects of healthcare.
But he questioned whether the technology in the sensors used to control the robots is advanced enough yet for them to carry out surgery without a doctor on hand to supervise.
"We're not there yet; we've got quite a long way to go - but in terms of using these tools as an aid to the surgeon, personally I don't think people would be that concerned," he said.
But it is widely thought that technological advances in sensors could lead to robots in the future being sensitive enough to carry out tricky surgical procedures.
Earlier this month, BBC News reported that £700,000 had been saved by the Forth Valley Royal hospital in Larbert by employing robots in pharmacy positions.
