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 - Agenda Reflection 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 - Reflection
In 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 - Agenda Reflection 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 - Reflection
Why 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 react
Light- 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.

20. Day 6 - Reflection What have you learned about the following things:
What is a robot (in your own words)
Building a robot
Programming a robot
What parts do robots need?

21. Day 6 – Group Activity Watch Search & Rescue Video Clip
What 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 – Instruction Understand loops exit with an “until” statement
Understand programming of the touch sensor

23. Day 6 – Challenge/Build Attach a touch sensor to your Bot
(pgs in large book)
Program the touch sensor
Write 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. Day 6 - Agenda Discussion/Reflection Watch Search & Rescue Video Clip
Understanding Programming – Touch Sensor & Loops
Writing directions – Search & Rescue
Writing directions – Bump & Run
Begin programming for Bump & Run Races

25. Day 7 - Reflection

How would they be used?

28. Day 8 - Agenda Discussion/Reflection Police Demonstration Create Maze
Writing directions – Maze
Program Bot to complete maze

29. Day 9 – Ultra Sonic Sensor
Ultra 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 Sensor
In what situations might an Ultra Sonic sensor fail?
Far away
Angle
Absorbency
Multiple surfaces
Multiple signals
