What a Robot can mean?• An automatic industrial

machine replacing the human in hazardous work.

• An automatic mobile sweeper machine at a modern home.

• An automatic toy car for a child to play with.

• A machine removing mines in a war field all by itself and many more…

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.

WHY ROBOTICS ?

• Speed.• It can work in hazardous/dangerous

environment.• To perform repetitive task.• Efficiency• Accuracy• Adaptability

Types of Robot

• Wheeled• Legged• Climbing• Flying

WAR FIELD SPY ROBO :FEATURES :Patrol the surroundings with sharp camera-eye.Send video and data captured to the server

wirelesslyEasy control by a remote through wireless

network Mobile in all directions with miniature sizeConceal in camouflage without attracting

attention
