Whether you know or not evolution of robots has given a tremendous change in technology
The robot story
Although there may be several ways of defining what a robot is, we like the simple way A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro which is guided by computer or electronic programming, and is thus able to do tasks on its own.
Robots don’t have to be anthropomorphic (like humans) or bestial (animal-like), but the bottom line is, they should be able to do things on there own, and adapt to changes in their environment.
Leonardo Da Vinci credited with the first design concept of a robot, around 1495. Williams Grey Walter’s Elmer and Elsie (1948) wee the first electronic autonomous robots that had touch and light sensors, two vacuum tubes basic analog circuit and could even recharge their own batteries. Shakey, the first mobile robot that had form by AI, was built by Stanford Research Institute Mobile robots have the capability to move around in their environment and are not fixed to one physical location. An example of a mobile robot that is in common use today is the automated guided vehicle or automatic guided vehicle (AGV). An AGV is a mobile robot that follows markers or wires in the floor, or uses vision or lasers.
Mobile robots are also found in industry, military and security environments. They also appear as consumer products, for entertainment or to perform certain tasks like vacuum cleaning. Mobile robots are the focus of a great deal of current research and almost every major university has one or more labs that focus on mobile robot research.
Primarily, the four areas where robots have been most useful are manufacturing, space exploration, the military and the healthcare. Typically, in these sectors, task that are repetitive, hazardous, or needed precision have been taken over the robots.
Types of robot
Robots, today could be autonomous, semi autonomous or fully controlled, and can broadly be classified into following types.
1. Manipulators:
Robotic manipulators are typically static (fixed-base) robots that are typically used in manufacturing. These are routinely visible in most assembly line factories all over the world, but a sequential phone-switching system could be called a manipulators.
2. Mobile robot:
Mobile robots have the capability to move around in their environment and are not fixed to one physical location. These are usually platforms with wheels, track or legs, we have already told about automated guided vehicle or automatic guided vehicle (AGV). And newer example is Honda’s AIBO (a
Humanoid that can run on speed of 6 kmph) and Sony’s AIBO look like a dog.
3. Telerobots:
Tele-operation is when a human operator controls a robot from a distance-of few feet or halfway across the solar system. The Sojourner robot, which explored the surface of the mars in 1957, is one such example. Unmanned aerial vehicles (UAVs) have been around since the Vietnam Wars, and UGVs (unmanned ground vehicles) and UUVs (unmanned underwater vehicles) have been since 1960’s.The mars robot ,Spirit and opportunity, have been working almost independently with timely teleported guidance from their NSA mentors since 2003
4. Virtual robot:
also know as bots or web-bots, these are actually software programming that simulates real robot or Function like human beings in the virtual world. WebCrawler’s and ELIZA – the chatterbot that simulates conversation between two people on the web –are example of virtual bots.
5: Shape –shifting robots:
Recently, platforms for robots have moved toward polymorphism. Serpentine robots are the best example of shape changing robots, Carnegie Mellon University’s biorobotic lab developed a snake –like modular robot called Uncle Sam that looks like s series of tin can and climbs poles and trees before it surveys the landscape with camera on its head.
6:Sawrm robots:
Inspired by colonies of insects such as ants and bees, researchers are modeling the behavior of swarms of thousands of tiny robots which together perform a useful task, such as finding something hidden, cleaning, or spying. Each robot is quite simple, but the emergent behavior of the swarm is more complex. The whole set of robots can be considered as one single distributed system, in the same way an ant colony can be considered a super organism, exhibiting swarm intelligence. The largest swarms
so far created include the iRobot swarm, the SRI/Mobile Robots CentiBots project] and the Open-source Micro-robotic Project swarm, which are being used to research collective behaviors. Swarms are also more resistant to failure. Whereas one large robot may fail and ruin a mission, a swarm can continue even if several robots fail. This could make them attractive for space exploration missions, where failure is normally extremely costly.
7. Nano robot:
Nanorobotics is the still largely hypothetical technology of creating machines or robots at or close to the scale of a nanometer (10−9 meters). Also known as "nanobots" or "nanites", they would be constructed from molecular machines. So far, researchers have mostly produced only parts of these complex systems, such as bearings, sensors, and Synthetic molecular motors, but functioning robots have also been made such as the entrants to the Nanobot Robocup contest. Researchers also hope to be able to create entire robots as small as viruses or bacteria, which could perform tasks on a tiny scale. Possible applications include micro surgery (on the level of individual cells), utility fog, manufacturing, weaponry and cleaning.
