How Do Robots Work?

   Wondering how robots work? Various robots operate in different ways, but they all share a similarity
in terms of their design and operation.

   Robots are made of a few basic parts :- a body, motors/engines that help move the parts of a robot, sensors that provide input to the robot and a microprocessor that acts as a brain. A robot may be programmed to perform the same actions over and over again , however most robots decide what to do based on the information from their surroundings. These robots need sensors to collect this information. For example, if a robot is programmed to move around obstacles it needs sensors in order to sense the presence of an obstacle. 

   However in order to understand the data collected by the sensors, a robot requires programming. Programming helps the robot understand the data given and to perform the required action. This programming in turn helps a robot's microprocessor tell the mechanical parts what to do. The microprocessor will state the position required of a part, the way it should be turned,etc.

   This process is the same for all robots no matter their differences in functioning,size,etc.
