Components of Robot

1. Manipulator
2. End effector
3. Locomotion Device
4. Controller
5. Sensors
6. Actuators

• ​A robot's manipulator is similar to the human arm, consisting of multiple joints and links.

• It provides flexibility and movement to the robot, allowing it to perform various tasks.

• Just as the human arm can bend and reach, the manipulator's joints and links enable the robot to reach different positions and orientations.

​Manipulator

• The end effector is located at the free end of the robot's manipulator.

• It serves a function similar to the human hand and fingers, allowing the robot to interact with its environment.

• The end effector performs tasks like gripping, picking up objects, or performing precise actions.

​

​End effector

​While humans rely on muscles for arm and hand movement, robots use motors for locomotion.

• These motors provide the power needed for the robot's movement, and they come in various types, including electric, hydraulic, and pneumatic.

• The choice of motor type depends on the robot's design and intended application.

​Locomotion Device:

• The controller in a robot is analogous to the human brain, directing its actions.

• It consists of both hardware and software components that enable the robot to carry out assigned tasks.

• The controller coordinates and controls the movements of the manipulator, end effector, and other components, making the robot perform specific functions.

​Controller

Sensors

• Sensors are vital components of a robot, serving as its "sense organs."

• They provide data and feedback to the robot's controller, allowing it to perceive its environment.

• Sensors measure various quantities such as position, velocity, force, torque, proximity, temperature, and more.

• This sensory input enables the robot to make informed decisions and adapt to changing conditions while executing tasks.

​Robots have mechanical components like different types of motors, servos, and arms that execute physical actions based on decisions made.
