2. Contents Architecture Parts of Robots Robot Control loop Robot Components Life Cycle

3. ‹#› Parts of Robots Power Supply From computer through ab type cable Batteries 9v, 12v Through Adapter Actuator motors convert electrical energy to mechanical Sensor for examining the environment 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.

7. 7 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.

8. 7 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

12. 7 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

14. Robotic Revolution

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.
