1961: Installation of the First Industrial Robot
Industrial robotics, an automation technology relying on the two technologies of numerical control and teleoperators, started to gain widespread attendance in the 1960s. The first industrial robot was installed at General Motors in 1961. Developed by Joe Engelberger and George Devol, UNIMATE obeyed step-by-step commands stored on a magnetic drum and with its 4,000 pound arm sequenced and stacked hot pieces of die-cast metal.

Satellites
Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.
On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of very small aperture terminals (VSAT). Such networks are independent and make mobile access possible.
In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
