What is a Robot?

• By Trevor Hunter

2
Robot

• A machine that resembles a human and does
  mechanical routine tasks on command
• Any machine or mechanical device that operates
  automatically with human like skill

3
Next Examples of Robotics

• There are several apects of a robot many believe
  a robot has to be mobile that is not the case it
  can just be an arm a leg or just a head as long
  as it is performing a human like task with
  percision

4
Robot Example number 1

• This robot is for production lines for manual
  labor and combining large parts that are
  manurfactured in assmbly.
• It uses its claw like hand to to grab large parts
  and place them on a line

5
Robot Example number 2

• This is a new robot kit you can purchuse for
  about 300 it can walk and navigate if you prgram
  it to it comes with an optional camera.

Robot example number 3

• Robots like this are used to go where humans
  cannot, this one in particuar is made for bomb
  disposal it will disarm a bomb using a water jet
  stream to puncter and disarm the trigger to the
  bomb they also use it to get close to hostage
  situations like this one this happened in a
  trailer park when I man took his wife hostage the
  man went crazy and shot the bot

How a Robot is made Up and Why they are made

• A robot is made up of the very same components. A
  typical robot has a movable physical structure, a
  motor of some sort, a sensor system, a power
  supply and a computer "brain" that controls all
  of these elements. Essentially, robots are
  man-made versions of animal life -- they are
  machines that replicate human and animal
  behavior.

Basics of a robot

• Many robots do have several qualities in common.
  Almost all robots have a movable body. Some only
  have motorized wheels, and others have dozens of
  movable segments, typically made of metal or
  plastic. Like the bones in your body, the
  individual segments are connected together with
  joints

9
Power?

• A robot needs a power source to be a functional
  machine most robots will use a battery even
  though some will use a plug in the wall if the
  robot is stationary so will not move out of the
  proximity of the cord attached to the wall

10
Internal workings of a Robot

• he actuators are all wired to an electrical
  circuit. The circuit powers electrical motors and
  solenoids directly, and it activates the
  hydraulic system by manipulating electrical
  valves. The valves determine the pressurized
  fluid's path through the machine. To move a
  hydraulic leg, for example, the robot's
  controller would open the valve leading from the
  fluid pump to a piston cylinder attached to that
  leg. The pressurized fluid would extend the
  piston, swiveling the leg forward. Typically, in
  order to move their segments in two directions,
  robots use pistons that can push both ways.

11
Explination of Previous Slide

• Basically in a robot the power source supplies
  the power supply that carries the current through
  the circuit for the electric motors to operate
  and segments of the robot to function and move
  like they should.

12
It has a brain?

• The robot's computer controls everything attached
  to the circuit. To move the robot, the computer
  switches on all the necessary motors and valves.
  Most robots are reprogrammable -- to change the
  robot's behavior, you simply write a new program
  to its computer.

13
Can Robots think on its own?

• Not exactly
• Basically a robot thinks what you tell it to if
  you program it to say that 228 then it will
  believe that 228 so basically you have to be
  sure what exactly what you want the robot to do
  so that you can program it to do what you want it
  to.

14
Just the Basics

• These are the basics of what a robot is made up
  of and how they work and function they is more to
  it but these are the basics of robot and
  functionality

15
The Basic Robot Kit

• Tribotz SpecificationsPower Source One 9V and
  two AA batteries Power Consumption Minimum
  current is 5mA (with motor on standby. Maximum
  current is 120mA (while operating motor). Power
  Voltage DC 3V Height 4.4 inches Length 5.8
  inches Width 6 inches
• This robot kit ii very basic andhas very basic
  and detailed instructions step by step procedures
  that come with it

Mid range to hard Robot kit

• The Boe-Bot has a high-quality brushed aluminum
  chassis that provides a sturdy platform for the
  servo motors and Board of Education - Serial
  Interface which is included this kit. The chassis
  has plenty of mounting holes and slots to add
  your own sensors and actuators. The rear wheel is
  a drilled polyethylene ball held in place with a
  cotter pin. Wheels are machined to fit precisely
  on the servo spline and held in place with a
  small screw.
• This kit includes everything you will need to get
  started though it is expensive it does have
  everything that you need

Parts?

• Instead of using a it you could also use just
  pieces of hardware. A robot does not have to be
  mobile so in the next couple slides I'm going to
  show parts that could be possible for use.

19
Breadboard

• To keep cost down we could use this to put our
  components down how we would program iit im not
  certain but we would need a microcontroller.

Proximetly Sensor

• Cherry CU101102. Magnetically actuated sensor.
  0.46" diameter x 1.41" long threaded body with
  mounting nut. 9' long, two-conductor cable.
• We could use this to see how we are to objects to
  explore the idea of navigation

21
A Compass?

• Magnetoresistive sensors can determine the change
  in earth's magnetic field due to the presence of
  a ferromagnetic object or position within the
  earth's magnetic field. The high bandwidth allows
  detection of vehicles and other ferrous objects
  at high speeds. The sensors are contactless and
  the working distance is dependent on the
  ferromagnetic mass it is measuring. Applications
  include Compassing and Navigation, Vehicle
  Detection, Virtual Reality, Laboratory
  Instrumentation, Medical Instruments, Underground
  Boring Equipment and Flux Gate Replacement.

My Robot Proposal

• I think it would be interesting to build a robot
  for navigation. Maybe using some of the parts I
  mentioned before we can accomplish a robot moving
  around a room or going from point A to point B or
  some other variation I'm not really sure what we
  can do with 25 dollars
