Robotics Introduction What is a Robot?

What are examples of a robot?What can robots do?What can’t robots do?How are robots used in our daily lives?

3

Definition of a Robot What is a Robot?

A robot is a device that is built to independently perform actions and interact with its surroundings.

4

Watch Video Clips After watching the video clips…

Which of the clips showed actual “robots?”

Explain the difference between a robot and a remote controlled machine/toy

5

Day 2 - Reflection How are robots used in our daily lives?

What is possible with a Robot?

What are some unexpected Robots?

6

Day 2 - AgendaReflection discussion

Finish building Tri-Bot

Label cables

Come up with a team and bot name and make poster for team

Watch video clips

Introduce basic programming

7

Day 3 - ReflectionIn what ways do robots need to

interact with their surroundings?

Give specific examples of a robot and the type of movement or sensors it will need.

8

Movement Define Types of movement:

Locomotion – The ability to move from place to place (move from place to place)

Localization – To perform functions in a specific area (turn head)

Manipulation – To touch or move by mechanical means (move other things around)

Cooperation - To work together (two motors working together for movement)

9

Day 3 - AgendaReflection discussion

Definitions of types of movement

Watch “Robo Cup Dog Soccer” identify each type of movement

Inventory of pieces

Review Programming

Begin programming with sound blocks

10

Day 4 - ReflectionWhy is it important to be specific

when giving directions?

Write down the step by step directions of how to fold a paper airplane.

11

What do we need the robot to do? Moving: The robot must be able to control

some set of actuators to move how and when we want it to. We must be able to reliably place the robot anywhere we want.

Sensing: The robot must be able to perceive its environment through sensors locate obstacles to avoid, and objects of interest that we want it to interact with.

Plan/Act: The robot must be able to make decisions using its processor based on it’s sensors and feed them to it’s actuators to be able to move.

12

What is a sensor? Takes readings from physical

environment and turns it into an electrical message/signal

Sensors we will work with: Touch- hit something and it reactLight- can sort by color or detect light

from dark Sonar/ultrasonic- tells how far away

things are Sound- tells how loud something is

13

What is a processor?It is the logic circuitry that

responds to and processes the basic instructions that drive a computer.

A computer needs to be able to: Receive inputs from the sensors, and

convert the sensor readings into perceptions

Make decisions based on it’s perceptions Use these decisions to change its

environment (or move itself in the environment) using its actuators.

Each of the above three things is programmed by the user using a programming language.

Takes readings from physical environment and turns it into an electrical message/signal Touch- hit something and it react

14

What is a processor?A computer needs to be able to…:

Each of the previous three things is programmed by the user using a programming language.

Takes readings from physical environment and turns it into an electrical message/signal Touch- hit something and it react

15

What is an actuator?Takes electrical message and turns it

into a physical action. For example:Electric motors receive electricity

which makes their axles turn. These can be connected to wheels, which can make the robot move

Pumps receive electricity which makes them compress liquid through tubes which can make a robotic arm move around. This arm can push, pull, and lift things in the world.

17

Day 4 - AgendaFinish Inventory

Begin programming with sound blocks

Discussion/Reflection

Giving clear directions – Paper Airplane

Definitions of types of processes

Review movement programming

Begin programming basic movement

18

Day 5 - ReflectionWrite directions for your teammates

to move through a maze within the classroom

Take turns testing each other's directions and see which teammate can write the clearest directions.

19

Day 5 - AgendaDiscussion/Reflection

Writing directions – Move through a maze

Writing directions – Dance moves

Begin programming for Dance Competition

20

Day 6 - ReflectionWhat have you learned about the

following things:What is a robot (in your own words)Building a robotProgramming a robotWhat parts do robots need?

21

Day 6 – Group ActivityWatch Search & Rescue Video ClipWhat do the robots need to be able

to perform these functions?Write directions for your teammates

to perform a search and rescue mission of a treasure of your choice. Include sensors and loops:Use “until”Use touch sensors

22

Day 6 – InstructionUnderstand loops exit with an “until”

statementUnderstand programming of the

touch sensor

23

Day 6 – Challenge/BuildAttach a touch sensor to your Bot

(pgs 49-53 in large book)

Program the touch sensorWrite a program for ‘Bump and Run’

using the ‘Loop’ block, where robots must run down a corridor, bump into a wall, and return to the start.

Bump & Run Races Have groups which complete this extend the program by

putting a ‘Forever’ loop around the previous program to make the robot continuously go back and forth between two walls.

24


Watch Search & Rescue Video ClipUnderstanding Programming – Touch Sensor

& Loops

Writing directions – Search & Rescue

Writing directions – Bump & Run

Begin programming for Bump & Run Races

25

Day 7 - ReflectionWhat did you have to change/modify

to get your Bot to be able to do the “Bump & Run” Challenge?Change designChange ProgramAdd stabilizers

26


Finish - Bump and Run – Race

Program - Bump, Turn, Continuous

Writing directions – Maze

27

Day 8 - ReflectionWithin the police department what

kind of robots or remote controlled machines do you think they would need?

How would they be used?

28


Police Demonstration

Create Maze


Program Bot to complete maze

29

Day 9 – Ultra Sonic SensorUltra Sonic sensor sends out a high

frequency chirp from one circle and the sound wave bounces off an object and returns to the microphone in the other circle.

Because sound travels at a constant speed ~1,125 ft/s the processor can calculate the distance the sensor is from an object and respond based on the programming.

30

Day 9 – Ultra Sonic SensorIn what situations might an Ultra

Sonic sensor fail?Far awayAngleAbsorbencyMultiple surfacesMultiple signals

31

Day 9 – Writing a ProgramIn your journal write out the

program directions for your Bot to make it through the maze using the touch sensor, the ultra sonic sensor and loops.
