Robot is a term with which almost all of us are quite familiar with. But most of us are unaware about the technical insights or aspects about these wonders of electronic trade. A robot is defined as "reprogrammable, multifunctional manipulator", designed to move materials, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks. It has a mechanical body and an electronic nerve system to drive it.

But the robot cannot perform task on its own. It does not have brain as we human being do. So how does a robot work. Here is the answer. For a robot to do something as desired and useful, we need to program it with some kind of intelligence. This can vary from hardwired logical circuits implementing some low-level reflex code to microcontrollers. In an advanced robotics systems, the control system can go up to neural network control systems running on powerful microcomputers networked together.

When someone decides to build a robot, the first thing that he would need is a robotic kit. Now the question arises what is a robotic kit. Well a robotic kit is your blueprint and comprises of all the tools and parts that a person would need for building a robot.

Robotic kits are available online along with manuals and robotic books which are of great help in building a robot. These robotic kits are available in various dimensions, depending on the customer's requirement.

The robotic kit includes the mechanical parts required for building a robot like metal or plastic parts, mechanical components & electrical motors. It also includes a manual which helps in building the robot. Robotic books are of great help and an added advantage to those interested in this field. Such books have all the latest updates about robots.

In Advanced robotics systems, the control system can go up to advanced neural network control systems running on powerful microcomputers, networked together. To be able to build a robot, a person needs to understand and learn all the aspects of above mentioned fields. Robotics is not a hobby, it requires skills, dedication and lot of hard work. Besides the obvious - mechanics, programming, and electronics, there are the less obvious skills of diligence and genuine curiosity.

Some of the robotic parts are:.

Sensors: which detect the state of the environment.

Actuators: which modify the state of the environment.

Control System: which controls the actuators based on the environment as depicted by the sensors.

The most developed robot part, in practical use today, is the robotic arm and it is seen in applications throughout the world. It is used to carry out dangerous work such as dealing with hazardous materials. It used to carry out work in the medical field such as conducting experiments without exposing the researcher.
