Why Robotics?

Tell me and I forget. Show me and I remember. Involve me and I understand.

WHAT IS A ROBOT?

Is a robot…– Man-made, reprogrammable brain in control of a

body?– Machine that mimics human and animal behaviors?– Mechanical device that performs pre-programmed

behaviors?

Definition actually varies from person to person in the industry.

WHAT IS A ROBOT?

A robot is defined as a machine with– Input – information that comes from sensors– Program – a set of instructions– Behavior – response to input or an environment– Output – result or product of input and program– Body – a physical object

WHAT IS A ROBOT?Basic robot parts– Moveable body– Actuators

• Electric motors, solenoids, hydraulic or pneumatic systems– Power source

• Batteries, AC power, compressed air– Electrical circuits

• Connect all actuators– Computer

• Controls all electrical circuits– Sensory system (optional)

Working robots

– Designed to do repetitive or dangerous tasks– Used mainly in factories– Often carry supplies or messages– Allow humans to focus on solving problems– Examples• Medical robots that perform minor or difficult surgical

procedures• Bomb disposal robots that handle dangerous explosives• Welding robots that help assemble automobiles

Exploring Robots

– Designed to explore places humans cannot go– Used by scientists and adventurers– Typically have sensors, actuators and mobile

power sources– Examples• Mars rovers Spirit and Opportunity• Robots that explore shipwrecks like the Titanic• Scientific probes to harsh-climates like a volcano or

glacier

Playing Robots

– Designed to entertain us– Used by robot hobbyists and kids– Typically have a gaming or competing behavior– Examples• Battlebots• RoboCup soccer• Toys
