Robots can be broadly divided into three units.
1. Mechanical Unit
2. Electronics circuitary.
3. Software section.
What ever type of Robot you take it will be comprised of these three units only.
Mechanical Unit:
These parts are gear boxes, frames, grippers, tracks, connectors, motor mounts, wheels. They constitute the body of robot. These parts basically help in robot performing its basic task. For example if robot has to move from one place to other, if it is a wheeled robot then it will move by the combination of motor and wheel assembly and if it is legged robot then it can walk with the help of legs.
The use of above mentioned part depends on the type of requirement you are having for your robot.
Electronics Circuitry:
This comprises of all electronics components and their connections with each other to perform a required task.
If robot is made of pure digital circuit then it will be combination of transistors, diodes,resistances and capacitors, by the combination of these, logic circuit will be created which will perform a certain kind of specific task.BEAM robots are the example of such kind of robots. If robot is made of embedded system, then it will be having processors, memory unit and other digital component based on type of robot.
One thing which all type of robots have in common is that they all have power source to provide power to the components used in circuitry. This power source could be a battery or it could be a voltage stepping down unit which will step down voltage and will rectify it to 'dc' so that it can be used by all components. Voltage level could be different for different block of circuit. In that case normally two sources are not used only one is used whose output is equal to input of one block and for other voltage is either step up or stepped down.
Software section:
Software is used in those robots which have microprocessor or micro-controller chips on them. Software is used to build logic or the functioning for robots. It decides that how robot will react under certain conditions. For example let us take example of wheeled robot which has to save it self from bumping into the wall. The logic for robot to save himself from bumping will be build in software and will be uploaded in the memory of processor. Robot will get information of wall through sensing elements and this information will be sent to processor. Based on the logic coded in software, processor will stop the motor and it will start rotating motor in opposite direction.Which will save robot from bumping into wall.
This was a broad division of parts. I know most of you must be thinking that I have not touched various other parts like sensors, actuators etc. Yes there are also parts of robot but as I said that it is a broad division of parts when I will deal with the functioning of robot I will go in detail in each of these terms and will explain them.
