Introduction • Robots are already taking up significant market share in the entertainment and toys and having an impact on education for primary, secondary and university students. They are also becoming more prevalent in private and government industries including health, mining, agriculture, rescue, security and defense. Much of this growth is due to improvements to battery and micro-processor technology.
What is a robot • A robot is a mechanical or virtual artificial agent, usually an electro-mechanical machine that is guided by a computer program or electronic circuitry. Robots can be autonomous, semi-autonomous or remotely controlled and range from humanoids such as ASIMO and TOPIO to Nano robots, 'swarm' robots, and industrial robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. The branch of technology that deals with robots is called robotics.
Types of robots • There are many types of robot, but I will try to cover at least a few here.Factory robots - Robots that are used in factories to replace human labour. Not all of these machines can be considered robots, some are just merely electric screwdrivers on a timer. • Space Probes/Rovers - These are not always entirely autonomous, some are controlled remotely, but they always include autonomous aspects which allow them to become aware of their surroundings. • AGV's Automated Guided Vehicles - Robots that navigate based on certain things such as heat.
Household Robots - Devices such as the Roomba which automatically moves around vacuum cleaning. • Military Robots - Devices such as autonomous vehicles and aircraft. • Educational Robots - Robots used in schools, these are really just simple robot kits which are designed to teach children about electronic sensors. • Soft robots - Robots which are made out of silicone. No primary use yet, as far as I know. • Swarm Robots - used like a swarm of insects, these are individually simple but work together to create something more complex. Often used for spying and performing tasks. • Humanoid Robots - mentioned earlier, these robots are designed to imitate human behaviour such as walking.
The Myths about Robots • And how film hasn't helped • There are many myths surrounding robots - but lets start with the basics. Robots are often not human imitations, in fact, most robots don't even have legs. This doesn't mean robots can't look like humans, several do, but such robots make up a very small proportion of all robots; these robots are called humanoid robots. Secondly, robots are often made to help do a task that is boring or arduous, they aren't made to kill humans! It's also worth noting that a robot cannot 'become bad'. This is a myth that has become about as a result of many Sci-Fi films.
