  1. Robotics Lego NXT Mindstorms

  2. 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 - 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.

  16. Day 4 - Agenda • Finish 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

  17. Day 5 - Reflection • Write 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.

  18. Day 5 - Agenda • Discussion/Reflection • Writing directions – Move through a maze • Writing directions – Dance moves • Begin programming for Dance Competition

  19. 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?

  20. 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

  21. Day 6 – Instruction • Understand loops exit with an “until” statement • Understand programming of the touch sensor

  22. Day 6 – Challenge/Build • Attach a touch sensor to your Bot (pgs 49-53 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.

  23. 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

  24. Day 7 - Reflection • What did you have to change/modify to get your Bot to be able to do the “Bump & Run” Challenge? • Change design • Change Program • Add stabilizers

  25. Day 7 - Agenda • Discussion/Reflection • Finish - Bump and Run – Race • Program - Bump, Turn, Continuous • Writing directions – Maze

  26. Day 8 - Reflection • Within the police department what kind of robots or remote controlled machines do you think they would need? • How would they be used?

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

  28. 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.

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

  30. Day 9 – Writing a Program • In 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.

  32. Day 10 – Reflection • What problems did you have calibrating or working with the Ultra Sonic Sensor? • In your journal re-write your program directions for going through the maze following the example on the board.

  33. Day 10 - Agenda • Discussion/Reflection • Ultra Sonic Sensor • Re-writing directions – Maze • Program Bot to complete maze using touch and ultra sonic sensors and loops. • For the groups that finish – Add grabber Arms to your Bot.

  34. Day 11 – Reflection • What has your team done well? • What does your team need to work on? • In what ways have you personally contributed to helping your team be successful? • What do you do that might get in the way of your team working together successfully?
