An introduction to the world of robotics. Making Sense of the Real World. How can the computer detect such widely different things as the whereabouts of a London Transport bus, fog, the length of an electronic flash or the speed of a motor? IAN MCNAUGHT -DAVIS and JOHN COLL look at a wide range of sensors which are available on the market. Production DAVID ALLEN and ROBIN MUDGE

Computers in Control

1. Introducing the Robot

First broadcast: 2nd March 1984
Duration 24:42

An introduction to the world of robotics. 1: Introducing the Robot: A visit to the Chicago Robotics Exhibition shows how the computer has revolutionised these mechanical servants and even made domestic versions possible. IAN MCNAUGHT-DAVIS begins to look at how computers can sense what's going on round them and then control mechanical devices. Production DAVID ALLEN and ROBIN MUDGE

5. Recognising the Obvious

First broadcast: 30th March 1984
Duration 24:36

An introduction to the world of robotics 5: Recognising the Obvious : We see, hear and interpret the real world with ease. For the computer it's not so easy, but some robotic systems can identify objects or voices and act accordingly, and it's possible to mimic these on the home microcomputer.
