What are Robots?


A mechanical device that is capable of
performing a variety of tasks on
command or according to instructions
programmed in advance.


Robotics is the science of studying
and creating robots


Although people have been imagining and
writing stories about robots for many
years, robotics has been a real science only
since the 1970's

mining


Replace Humans with Robots

Why Robots?

Better Than Humans?


Robots at WTC…


Enter places
smaller than
person could
enter


Resistant to fire
and can survive
without oxygen


Do Things that Living Things Can’t

7

Industrial Manipulators



High precision, fast repetition


Usually no sensing of the environment


Welding can be off by an inch…

3 Ways of Controlling a Robot


“RC
-
ing”


you control the robot


you can view the robot and it’s
relationship to the environment


ex. radio controlled cars, bomb
robots


operator isn’t removed from scene

3 Ways of Controlling a Robot


teleoperation


you control the robot


you can only view the environment
through the robot’s eyes

3 Ways of Controlling a Robot


semi
-

or full autonomy


you might control the robot sometimes


you can only view the environment through
the robot’s eyes


ex. Sojouner with different modes


human doesn’t have to do everything

Nanotechnology


A new scientific frontier that will impact
many facets of society


The nano world is 100,000 times
smaller than the thickness of a single
strand of hair.


The Nano Quest robot game mission
models represent just some of the
technology and ideas that scientists
are thinking about or working on right
now.

Running programs on the NXT


Use the arrow keys to find "My Files"


Use the orange key to enter the menu.


Find and enter the "Software files" menu.


This is where all of the programs you download
will be stored on the NXT.


Find your downloaded program.


It should be the same name as the file on the
computer.


Select "Run" from the menu to run the
program.

Navigating NXT Menus


Arrow Keys: move left or right through a
menu


Orange Button: think of this as "enter"


Rectangular Button below Orange Button:
think of this as "exit" or "escape"

In the last section you learned how to run a
program on the NXT. You used the keys to
navigate to a specific point in the NXT
menu system. Here is a summary of what
the buttons do.

32

Turning off the NXT


To turn off the NXT, you use the
rectangular button below the orange
button.


Press this rectangular button
repeatedly until the menu asks if you
want to turn off the NXT.


At this point, you will need to use the
orange button to select "Yes." This will
turn the NXT off.

Once you are finished, try changing
some parts of your robot and make it
