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
