In the 2002 motion picture adaptation of the book 'The Time Machine', the VOX system showed how advanced interactive technology could be in the future. Although the 'compendium of knowledge' is far from reality, a decent attempt has been made. Shimizu Corp and Yasukawa Electric Corp have opened the "Smart Showroom" that is part of the Smart Robotics Building Project, which will demonstrate the use of Smart Robots in intelligent buildings. Robots will take on the role of receptionist, guards, office cleaners, etc and replace humans.
Although as guards, robots could be humorous opponents, but the idea is not meant to rely on robots for all functions, rather be a combination of all technologies with the intervention of humans for device control, information and telecommunication technologies. The next times you visit a new building don't be surprised to see half-life like drones monitoring your every move.
