The field of robotics is a broad one, and great progress has been made in the development of robotic vehicles, aircraft, special purpose robots, space robots and many more types. They make a difference in our lives daily, whether you know it or not. But there is another kind coming that will definitely involve you on a daily basis. Soon.
They are
Androids.

Regardless of their ultimate utility, people are obsessed with robots that mimic the human form, i.e., "anthropomorphic" robots. The allure of creating a machine in our own image seems to be irresistible. Do we want them to take care of us? To be more powerful in many ways?
In the aftermath of World War II, the Japanese major cities had been devastated, the culture was under tremendous stress as the Japanese re-invented themselves, and life was generally really hard. In the 1950's, a comic strip began, staring
Tetsuwan Atom, also known as "Astro Boy" or "Atom Boy". Tetsuwan Atom was a robot, built in the image of the deceased son of a scientist. He had many special powers and after a rough childhood he dedicated himself to adventure and battling threats to mankind.

The android, Tetsuwan Atom, remains beloved by the Japanese. When I've talked to researchers at several of the top robotics labs in Japan, they frequently cite Tetsuwan Atom as an inspiration for their current work in robotics -- much of which involves anthropomorphic robots.
I'll write more on robots later. Today I stumbled across a web site that illustrates the importance of androids to many people from all walks of life:
Android World. This internationally popular site aggregates information on android projects world wide as well as provides other interesting information on the history of androids.
