2. A BRIEF INTRODUCTION:
• A servomotor is a rotary actuator that allows for precise control of angular
position, velocity and acceleration. It consists of a suitable motor coupled
to a sensor for position feedback. It also requires a relatively sophisticated
controller, often a dedicated module designed specifically for use with
servomotors.
• Servomotors are not a specific class of motor although the
term servomotor is often used to refer to a motor suitable for use in a
closed-loop control system.
• Servomotors are used in applications such as robotics, CNC machinery or
automated manufacturing.

4. Robotic arm
Description:
1.A robotic arm is a robotic manipulator, usually programmable, with similar
functions to a human arm .
2.Servo motor is used for joint rotation, it has about same number of degree of
freedom as in human arm.
3. Humans pick things up without thinking about the steps involved. In order for a
robot or a robotic arm to pick up or move something, someone has to tell it to
perform several actions in a particular order.
4. we can control each joint through computer interface to rotating the wrist to
opening and closing the hand or fingers.

8. Application of Robotic Arm
The robotic arm can be designed to
perform any desired task such as
welding, gripping, spinning etc.,
depending on the application. For
example robot arms in automotive
assembly line perform a variety of
tasks such as wielding and parts
rotation and placement during
assembly.

9. In space the space shuttle Remote
Manipulator system have multi
degree of freedom robotic arms that
have been used to perform a variety
of tasks such as inspections of the
Space Shuttle using a specially
deployed boom with cameras and
sensors attached at the end effector.

10. In medical science: "Neuroarm" uses
miniaturized tools such as laser scalpels
with pinpoint accuracy and it can also
perform soft tissue manipulation,
needle insertion, suturing, and
cauterization.
