The International Organisation of Standards released the latest standards for care robotics earlier this week.
The standards define the requirements for safe design of personal care robots with an emphasis on mobile servant robots, physical assistant robots and person carrier robots that aim to improve quality of life of the user, irrespective of age or capabilities.
The standards outlines hazards with the use of these types of bots, with the requirements and guidelines attempting to reduce risk and hazards at least to an acceptable level.
A point of note is that these specifications only apply to earthbound robots, so your personal space care robots will have to find the appropriate standards for that.
