Embedded system which is designed to perform a certain particular task as per the user requirements and it will interface hardware kit and programming software part. In the field of robotics an autonomous robots which perform a specific task accordingly without any control from human just it is based on programming in which how it was instructed. A microcontroller is a programmable digital processor with necessary peripherals. Both microcontrollers and microprocessors are complex sequential digital circuits meant to carry out job according to the program/instructions. Sometimes analog input /output interface makes a part of microcontroller circuit of mixed mode (both analog and digital nature).
Robots are those machine which suppress the human resource for executing particular task and it is used in an industrial sector for manufacturing of goods, processing and transportation. So only it will be possible through the concept of embedded system where the control mechanism was designed and developed with the controller circuits as interfacing various sensors, integrated circuits and other active and passive devices. Mostly we use L293D H-bridge IC for the driven of robotics motor mechanism. In the field of robotics technology an embedded system is one of the part to run the robot with predefined instruction. Controller circuit gives the predefined instruction at any particular instant of time which is upload through coding in embedded c programming through which the robot operates accordingly. The scope of robotics are in the field of Artificial Intelligence (AI), Internet of things (IOT) and Voice Recognition Technique where a robot operates through an android application.
