What is a robot?
The word robot is very general. It comes from
the Czech word robota which means industrial
labor .

• A robot is a mechanical and electrical device
  that can perform preprogrammed physical tasks.
• An intelligent and obedient but impersonal
  machine
• Any machine that does work on its own,
  automatically after it is programmed by humans.

What is a robot?
Examples of Robots and Non-Robots in Everyday Life
Robot Non-Robot
Alarm clock Walkman
Timed traffic light Car
Microwave Typewriter
Photocopier Bicycle
VCR/Tivo Flashlight
Remember our definition of a robot Any machine
that does work on its own, automatically, after
it is programmed by humans.
Elektro and Sparko Two of the first robots
(1939)
Seven feet tall, weighing 300 pounds, humanoid in
appearance, it could walk, talk, breathe, and
move its head and arms.

What are robots good for?

• Robots are useful for
• Doing the same task over and over again
• Going places too dangerous for humans
• Guarding buildings
• Building things
• Vacuuming your house
• Entertainment

• Unlike humans
• Robots never get bored or tired
• Robots never need to rest
• Robots never get sick

Autonomous Robots
Autonomous means something that is independent
and is not controlled by others. For a robot,
this means that it can make decisions and control
itself without a human guiding it.
Autonomous robots have different kinds of sensors
to help it make decisions, just like you!
Sensors detect different things (light, sound,
movement, etc.) and turn them into electrical
signals.
An autonomous robot can use its sensors to detect
things that are in its way and make a decision to
move around those things. This is called
obstacle avoidance.
An autonomous robot might also need to know where
it is. It can use other sensors such as a
camera, a GPS, and wheel encoders to help it to
localize itself in the environment.

Autonomous Robots
Robots cant think like a human, even though
people are working on artificial intelligence or
computer thinking. Instead, they make decisions
by using algorithms which are just procedures or
recipes. In a robot, some of these algorithms
are called controllers.
A lot of work and research is being done now with
teams of robots. With several robots cooperating
with each other and with humans, the team can
accomplish more than a single robot by itself.
When you go on a trip, you may have a map and sit
down before you leave to plan where you are
going. In the same way, autonomous robots can
take what they know about where they are and
where they want to go and plan a path of how to
get there. This is a called path planning.

Types of Robots Industrial
Joints

• Industrial Robots make up 90 of all robots that
  are used today

Links

• Industrial Robots are used in factories for

• assembling products
• handling dangerous materials
• spraying on finishes
• inspecting parts, produce, and even livestock
• cutting and polishing products

• Industrial Robots might also be called robotic
  arms or manipulators

Types of Robots Mobile
Mobile robots are the largest group of robot
types.

• Include many types
• Climbing
• Walking
• Humanoid
• Wheeled

The hardest thing for a robot to do is one of the
easiest things for a human to do walk!

Types of Robots Aerial (Flying)

• UAV Unmanned Aerial Vehicle
• Airplanes, helicopters, blimps
• Used for surveillance from high in the sky
• Fly by themselves
• Small helicopter UAVs could be used to search for
  people trapped in a building after an earthquake
