Sleeping with the robot ... waking up to automation

A robot was hitherto regarded as a cold body with a cool mind, to be used at assembly lines, warehouses, mines, and even at homes to perform simple tasks like vacuum-cleaning and laundry.

Such machines have now evolved into "intellectual robots". They find application in various sectors, including security, medical services and aerospace.

That's not all. They can replace human beings as teachers, coaches and therapists. And, even as sex partners.
