Parts of Robots
1. Power Supply
- From computer through ab type cable
- Batteries 9v, 12v
- Through Adapter
1. Actuator
- motors convert electrical energy to mechanical
1. Sensor
- for examining the environment
1. Controller
- central microprocessor that controls their movements
4. Robot Components
Controller:
Similar to cerebellum. It controls and coordinates the motion of the
actuators.
Processor:
The brain of the robot. It calculates the motions and the velocity of the
robot’s joints, etc.
Software:
Operating system, robotic software and the collection of routines.
Manipulator or Rover:
Main body of robot (Links, Joints, other structural element of the
robot)
5. Robot Components
End Effector:
The part that is connected to the last joint hand) of a manipulator.
Actuators:
Muscles of the manipulators (servomotor, stepper motor,
pneumatic and hydraulic cylinder).
Sensors:
To collect information about the internal state of the robot or To
communicate with the outside environment.

Artificial Intelligence
Artificial intelligence is the intelligence exhibited by
machines or software, and the branch of computer science
that develops machines and software with intelligence. Major
AI researchers and textbooks define the field as "the study
and design of intelligent agents",[where an intelligent agent is
a system that perceives its environment and takes actions
that maximize its chances of success.
John McCarthy, who coined the term in 1955,defines it as
"the science and engineering of making intelligent machines.

Sensors
⮚ Sensors provide awareness of the environment by sensing things.
Sensors are the core of robots. It is the system that alerts the
robots..
⮚ Sensing can be in different forms like-
• Light
• Sound
• Heat
• Chemicals
• Force
• Object proximity
• Physical orientation/position
• Magnetic & Electric Fields
• Resistance

Actuator
2. Manipulations
• Degrees of freedom
– independently controllable components of
motion
– Each plane in which a robot can maneuver
– Rotate Base Of Arm
– Pivot Base Of Arm
– Bend Elbow
– Wrist Up And Down
– Wrist Left And Right
– Rotate Wrist

Actuator
2. Manipulations
• Arms
– convenient method to allow full movement in 3D
– more often used in fixed robots due to power & weight
– even more difficult to control!
• due to extra degrees of freedom
• End Effectors/ Grippers
– In robotics, an end effectors is the device at the end of a
robotic arm, designed to interact with the environment.
– End effectors may consist of a gripper or a tool.
– The gripper can be of two fingers, three fingers or even
five fingers.
– may be very simple (two rigid arms) to pick up objects
– may be complex device with fingers on end of an arm
– probably need feedback to control grip force

15. Robot Lifecycle
RPA development life cycle is a
blueprint that consists of the
processes of the organization
to be automated, the criteria to
follow, the deployment of a bot,
and constant monitoring once
the bot is in place.
