What is a robot

What is a Robot?

By Trevor Hunter


Robot

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


Next examples of robotics

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


Robot example number 1

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


Robot example number 2

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

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

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

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

Power

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

Internal workings of a robot

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.

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.


It has a brain

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.

Can robots think on it s own

Can Robots think on it’s own?

  • Not exactly

  • Basically a robot thinks what you tell it to if you program it to say that 2+2=8 then it will believe that 2+2=8 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.


Just the basics

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

  • Next robot kits


The basic robot kit

The Basic Robot Kit

Tribotz Specifications:Power 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

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

Sensors

Sensors

What’s Included • Infrared Front-Facing Sensor • Infrared Down-Facing Sensor• Electrical Components and Connectors• Mechanical Fasteners

What’s Covered • Attaching the Sensors• Writing Sensor Code• Avoiding Walls and Other Obstructions• Retreating from Stairs and Table Edges• Using Define Statements in C• Tracking Lines on the Floor

This is just a Add on pack that includes mounts and sensors

Parts

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.


Breadboard

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

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

A compass

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

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
