1940s - 1950s: The Development of Early Robotics Technology

During the 1940s and 1950s two major developments enabled the design of modern robots. Robotics generally is based on two related technologies: numerical control and teleoperators.

Numerical control was invented during the late 1940s and early 1950s. It is a method of controlling machine tool axes by means of numbers that have been coded on media. The first numerical control machine was presented in 1952 at the Massachusetts Institute of Technology (MIT), whose subsequent research led to the development of APT (Automatically Programmed Tools). APT, a language for programming machine tools, was designed for use in computer-assisted manufacturing (CAM).

First teleoperators were developed in the early 1940s. Teleoperators are mechanical manipulators which are controlled by a human from a remote location. In its typical application a human moves a mechanical arm and hand with its moves being duplicated at another location.

Racism on the Internet

The internet can be regarded as a mirror of the variety of interests, attitudes and needs of human kind. Propaganda and disinformation in that way have to be part of it, whether they struggle for something good or evil. But the classifications do no longer function.
During the last years the internet opened up a new source for racism as it can be difficult to find the person who gave a certain message into the net. The anarchy of the internet provides racists with a lot of possibilities to reach people which they do not possess in other media, for legal and other reasons.

In the 1980s racist groups used mailboxes to communicate on an international level; the first ones to do so were supposedly the Ku Klux Klan and mailboxes like the Aryan Nations Liberty Net. In the meantime those mailboxes can be found in the internet. In 1997 about 600 extreme right websites were in the net, the number is growing, most of them coming from the USA. The shocking element is not the number of racist pages, because still it is a very small number compared to the variety of millions of pages one can find in this media, it is the evidence of intentional disinformation, the language and the hatred that makes it dangerous.
A complete network of anti-racist organizations, including a high number of websites are fighting against racism. For example:

Chappe's fixed optical network

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.

Because this communication system was destined to practical military use, the transmitted messages were encoded. The messages were kept such secretly, even those who transmit them from tower to tower did not capture their meaning, they just transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.

Forerunners of Chappe's optical network are the Roman smoke signals network and Aeneas Tacitus' optical communication system.

For more information on early communication networks see Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks.

Sony Corporation

Japanese SONY KK, major Japanese manufacturer of consumer electronics products. Headquarters are in Tokyo. The company was incorporated in 1946 and spearheaded Japan's drive to become the world's dominant consumer electronics manufacturer in the late 20th century. The company was one of the first to recognize the potential of the consumer videotape market. In 1972 it formed an affiliate to market its Betamax colour videocassette system. In 1987-88 Sony purchased the CBS Records Group from CBS Inc., thus acquiring the world's largest record company. It followed that purchase with the purchase in 1989 of Columbia Pictures Entertainment Inc.
