A robot has been one of science & technology's greatest contributions to the world of humans, especially when it comes to making our lives simpler. Run by computers and doing the work of humans, these robots are fantastic substitutes for humans, especially when it comes to repetitive work with little requirement for conscious thought. These robots can be programmed to perform the tasks individually, i.e. without any human involvement, or may be controlled remotely through a radio controller, depending on the kind of robot it is as well as the kind of work that needs to be done.
Robots are nothing but machines that are formed by the combination of more machines, each performing an individual function to aid the overall functionality of the robot. For e.g. if a robot needs to clench a fist, simple machines like levers and joints will do what they are built for, eventually providing the kind of cumulative output that results in the clenching of the fist. The sequence in which those simple machines do the inside job is always predefined in a set of programs that control each and every aspect of a robot's actions.
Everything about Robots
Robots are basically a collection of mechanical parts that are controlled by a computer or a processor. These computers and processors combine to decode and implement programming language in order to command the robot to perform certain functions. These machines can be programmed to perform specific functions, which is always easier, as well as be programmed to work on various different functions, which is obviously a harder and longer process to plan & create.
The Chinese are known to have created the world's first robot in the third century BC, where it was known as the artificer and was made out of leather, wood, glue and lacquer. The robot was a life-sized human figure that interacted with the audience in the court of King Mu of Zhou. However, the most practical use of robots or mechanical aids started when water clocks were created to measure time. The Chinese came up with these methods in the sixth century BC while the Greeks & Romans used these water clocks in brothels to time their customers' visits.
With the industrial revolution coming in, not only did the industrial world improve production, they also found new ways of employing machines to do the job of humans in a quicker and more efficient way. No longer was there any need for breaks or the chances of something going wrong due to the lack of focus or ability. Every robot or machine was designed to perform mechanical functions, either aided by a human or on their own.
Today, technology has allowed us to implant smaller and faster processor chips inside robots, making them smarter and capable of handling a lot more tasks without compromising on quality or precision.
If you are planning to build your own robot, you need to know what you want it to do before anything else. Once you have an idea of what it has to do, you will get a better idea of what your robot will need to do that. If you want it to carry a tray, it will require something that can hold a flat surface. If you want it to undo nuts and bolts, it will require the necessary tools to do so. Basically, you are unlikely to create a robot that can do everything that a human can, so you will need to start your building process with a clear plan in mind as well as a clear path forward.
There are many different types of robots that you can build and when you are learning how to build or make robots, you can go through books or websites to understand how to handle the mechanical, electrical and electronic parts of the robot, along with the programming bit. You can get plans for everything over the Internet while those people who have experienced the building process before, can make their own plans even. Finally, you will need the parts and the tools to do the job, which will depend basically on the kind of robot you are building. A moving robot will require wheels, which you can make from scratch or just pull off of abandoned supermarket trolleys, etc.
Depending on your expertise, you can build your robot from scrap or from new or refurbished parts bought in stores or over the Internet. You can even recycle your old appliances to use its parts but make sure you have permission from your parents or spouse before you go about dismantling their dishwasher.
Robots as a Hobby
One of the main uses of robots has been in the world robot wars, where you build battle-ready robots, or battlebots, and pit them against other humans. Robots are controlled by remote and these robot battles are all about finding the parts, building your own little robots and using a remote controlled to fight against other robots in an arena. Robots get damaged, sometimes beyond repair even, but there are winners too and sometimes, they get a pretty decent winners package to make up for those losses.
There are few hobbies that are as versatile and entertaining as building your own robot. Whether you simply enjoy running them or prefer the building part more, you are guaranteed hours and days of fun with robots. As long as you know your way around tools and have a good plan on your mind, you are likely to end up with something quite interesting that will keep you hooked onto the world of robots.
