Not Easy is it? Well easy for a human PSW but just think for a moment about a ROBOT.
Assume that a robot enters a two bed residents room with prior instruction to enter room xxxx and make the beds. First the robot has to enter the room & locate the beds. Then there is the problem that not all beds are the same. Then there is the problem of identifying all the bed clothes & so on & so on. Easy task for a PSW but not an easy task to train a robot. Also there are many tasks for which the robot must be trained.
It is not my intent to suggest that PSWs are underpaid & thanks also that there are many humans who all find what they will see as a simple task easy to do.
