ROBOTICS
It is a field of Engineering that covers the mimicking of human behavior.
Robotics includes the knowledge of Mechanical, Electronics, Electrical & Computer Science Engineering.
Components of ROBOTS
Structure
Power source
Actuation
Sensing
Structure
The structure of a robot is usually mostly mechanical and can be called a kinematic chain.
The chain is formed of links (its bones), actuators (its muscles), and joints which can allow one or more degrees of freedom.
Power Source
Suitable power supply is needed to run the motors and associated circuitry.
Typical power requirement ranges from 3V to 24V DC.
220V AC supply must be modified to suit the needs of our machine.
Batteries can also be used to run robots.
Robots are driven by different motors :-
DC Motors
Stepper Motors
Servo Motors
DC Motors
As the name suggests, a motor which uses a DC (Direct Current) power.
Can run in both directions.
Speed Controllable
Stepper Motors
Used for measured rotation
Can be held at a particular position of the shaft.
Ideal for many autonomous robots requiring higher precision.
Servo Motors :
Used in closed loop control systems in which work is the control variable.
An integral feedback device (resolver) or devices (encoder and tachometer) are either incorporated within the servo motor or are remotely mounted, often on the load itself.
ACTUATION
Actuators are the "muscles" of a robot, the parts which convert stored energy into movement.
The most popular actuators are electric motors.
ADVANTAGES
Revolution in Medical science and Health care systems.
New & wide scope in Education & Training.
A good help in Nuclear industry.
Used tremendously in Sports activities.
Play the role of an efficient assistance in Research and Development sciences.
Can very well handle household business.
