- 3. Robot is a system with a mechanical body, using computer as its brain.Robotics is the science and study of robots. Integrating the sensors and actuators built into the mechanical body, the motions are realized with the computer software to execute the desired task. Robots are more flexible in terms of ability to perform new tasks or to carry out complex sequence of motion than other categories of automated manufacturing equipment. INTRODUCTION:
- 4. There is no precise definition, a re-programmable , multifunctional ,automatic industrial machine designed to replace human in hazardous work. It can be used as • An automatic machine sweeper. • An automatic car for a child to play with. • A machine removing mines in a war field. • In space. • In military and many more… WHAT IS A ROBOT…?
- 5. Robots can also do the same thing over and over again without getting bored. Robots can explore inside gas tanks, inside volcanoes, travel the surface of Mars or other places too dangerous for humans to go where extreme temperatures or contaminated environments exist. Can do work with accuracy. WHY IS ROBOTS NEEDED…?

- 7. The robot's movement is controlled by two Direct Current (DC) gear motors with an encoder. The two motors are driven using a motor driver. The motor driver is interfaced into an embedded controller board, which will send commands to the motor driver to control the motor movements. The encoder of the motor is interfaced into the controller board for counting the number of rotations of the motor shaft. This data is the odometry data from the robot. There are ultrasonic sensors, which are interfaced into the controller board for sensing the obstacles and measuring the distance from the obstacles. There is an IMU sensor to improve odometry calculation. The embedded controller board is interfaced into a PC, which does all the high- end processing in the robot. Vision and sound sensors are interfaced into the PC and Wi-Fi is attached for remote operations.
- 8. Most robots are composed of 3 main parts: 1.The Controller ‐ also known as the "brain" which is run by a computer program. 2.Mechanical parts ‐ motors, pistons, grippers, wheels, and gears that make the robot move, grab, turn, and lift. These parts are usually powered by air, water, or electricity. 3.Sensors ‐ to tell the robot about its surroundings. Sensors allow the robot to determine sizes, shapes, space between objects, direction, and other relations and properties of substances. PARTS OF A ROBOT:

- 10. The most common types of Robots are.. • Mobile Robots. • Stationary Robots. • Remote-Controlled Robots. • Autonomous Robots. • Virtual Robots. TYPES OF ROBOTS:
- 11. 1.ROLLING ROBOTS: Rolling robots have wheels to move around. They can quickly and easily search. However they are only useful in flat areas. 2.WALKING ROBOTS: Robots on legs are usually brought in when the terrain is rocky. Most robots have at least 4 legs; usually they have 6 or more. MOBILE ROBOTS
- 12. • Robots are not only used to explore areas or imitate a being. • Most robots perform repeating tasks without ever moving an inch. • Most robots are ‘working’ in industry settings and stationary. STATIONARY ROBOTS:
- 13. A person can guide a robot by remote control. A person can perform difficult and usually dangerous tasks without being at the spot where the tasks are performed. REMOTE-CONTROL ROBOTS:
- 14. AUTONOMOUS ROBOTS: Autonomous robots are self supporting or in other words self contained. In a way they rely on their own ‘brains’.
- 15. VIRTUAL ROBOTS: Virtual robots don’t exits in real life. Virtual robots are just programs, building blocks of software inside a computer.
- 16. 1. Robotics and automation can, in many situations increase productivity, safety, efficiency, quality and consistency of product. 2. Robot can work in hazardous environments without the need of life support, comfort or concern about safety. 3. Robot needs no environmental comfort such as lightning, air conditioning, ventilation and noise protection. 4. Robots work continuously without experiencing fatigue or boredom and need medical insurance or vacation. ADVANTAGES
- 17. 1. High standard of maintenance maintenance required. 2. In case of the break down, the cost of repair may be very high. 3. Complex and expensive equipment to buy and install. 4. They can perform the repetitive tasks for long but they do not get better with experience such as the humans do. DISADVANTAGES
- 18. The World's First Robot Citizen On October 25, Sophia, a delicate looking woman with doe-brown eyes and long fluttery eyelashes made international headlines. She'd just become a full citizen of Saudi Arabia - - the first robot in the world to achieve such a status.

- 20. Today we find most Robots working for people in industries, factories, warehouses and laboratories. Robots are useful in many ways. For instance, boosts economy because businesses need to be efficient to keep up with the industry competition. Therefore, having Robots help business owners to be competitive, because Robots can do jobs better and faster than humans. CONCLUSION
