26. Power Supply - The working power to the robot is provided by
batteries, hydraulic, solar power, or pneumatic power sources.
Actuators - Actuators are the energy conversion device used
inside a robot. The major function of actuators is to convert
energy into movement.
Electric motors (DC/AC)- Motors are electromechanical
component used for converting electrical energy into its
equivalent mechanical energy. In robots motors are used for
providing rotational movement.
Sensors - Sensors provide real time information on the task
environment. Robots are equipped with tactile sensor it imitates
the mechanical properties of touch receptors of human
fingerprints and a vision sensor is used for computing the depth in
the environment.
Controller - Controller is a part of robot that coordinates all
motion of the mechanical system. It also receives an input from
immediate environment through various sensors. The heart of
robot's controller is a microprocessor linked with the input/output
and monitoring device. The command issued by the controller
activates the motion control mechanism, consisting of various

27. Some of the important components of Robots are as follows:
1. Manipulator:
Just like the human arm, the robot consists of what is called a manipulator having several joints and
links.

2. Endeffector:
ADVERTISEMENTS:
The base of the manipulator is fixed to base support and at its other free end, the Endeffector is
attached.
The Endeffector is expected to perform tasks normally performed by the palm and finger arrangements
of the human arm.
3. The Locomotion Device:
In the case of Human Beings the power for the movement of the arm, the palm and fingers is provided
by muscles. For the robot the power f
or the movement (locomotion) is provided by the motors. The motors used for providing locomotion in
robots are of three types depending on the source of energy: Electric, Hydraulic or Pneumatic.
4. The Controller:
The digital computer (both the hardware and the software) acts as a controller to the robot. The
controller functions in a manner analogous to the human brain. With the help of this controller, the
robot is able to carry out the assigned tasks. The controller directs
and controls the movement of the Manipulator and the Endeffector. In other words, the controller
controls the robot.
5. The Sensors:
ADVERTISEMENTS:
Without the data supplied by the sense organs, the brain would be incapable of intelligence. In other
words the controller (the computer) of the robot cannot do any meaningful task, if the robot is not with a
component analogous to the sense organs
of the human body. Thus, the fifth and the most important component of the robot is the set of sensors.
Sensors are nothing but measuring instruments which measures quantities such as position, velocity,
force, torque, proximity, temperature, etc.
