  1. Somerset Berkley Regional High School Robotics Engineering with LabView

  2. 1. Engineering Design • Central Concepts: Engineering design involves practical problem solving, research, development, and invention/innovation, and requires designing, drawing, building, testing, and redesigning. Students should demonstrate the ability to use the engineering design process to solve a problem or meet a challenge. Ma.Science and Engineering Framework 2006

  3. Standard 1.1 1.1 Identify and explain the steps of the engineering design process: identify the problem, research the problem, develop possible solutions, select the best possible solution(s), construct prototypes and/or models, test and evaluate, communicate the solutions, and redesign. Identify the problem Research the problem Redesign Communicate the solutions Develop solutions Select the best solution Test and evaluate Construct a prototype Ma.Science and Engineering Framework 2006

  4. Step 1 Identify the problem Write down the original problem here. Student - Design, build and program a robot to: climb a rope Ma.Science and Engineering Framework 2006

  5. Step 2 Research the problem Explore other options via the internet Student: List the internet sites that were helpful. Site 1_http://www.legorobot.pl/project.php?pr=ropeclimber&lg=en____________________ Site 2__http://ncostaengineering.weebly.com/rope-climber.html___________________ Site 3 _http://www.youtube.com/watch?v=bMmAUnka_MA&feature=related____________________ What did you learn from your research? A _Use friction to climb the rope_____________________ B _Use either gears or wheels for friction_____________________ C _Only use wires to attach the nxt to the motors_____________________

  6. Step 3 Develop solutions BRAINSTORM COLLABORATION • Student : Share your ideas with your design team. List your ideas below. • Build a robot with motor only attached to the wires to eliminate excess weight____________________________________ • Build a feeder to have the rope go straight into the gears that will climb the rope_____________________________________ • Build a robot that uses wheels to climb the rope____________________________________- Ma.Science and Engineering Framework 2006

  7. Step 4 Select the best Possible solution(s) Student: Describe which solution(s) best meet the need or solve the problem. Describe exactly what idea or mixture of ideas your design team decided on for the first robot prototype? Use the next slide to respond. Ma.Science and Engineering Framework 2006

  8. Student : Skillfully and imaginatively describe what your first prototype will look like. The robot will have two motors parallel to each other but they will be close enough to have gears climb the rope. The nxt computer will hang from the wires of the motors.

  9. Step 5 Construct a prototype Student: Build a robot with your nxt lego kit Use the next slide(s) for your digital pictures of your prototypes. Ma.Science and Engineering Framework 2006

  10. First Prototype picture

  11. 2nd Prototype picture

  12. 3rd Prototype picture

  13. Step 6 Test and Evaluate the solution(s) • Does it work? • Did it perform as expected? • What changes are necessary? • Does it meet the original design constraints? • Can it be manufactured? • Is it safe? • What happens to the products when its useful • life is finished? • USE THE NEXT SLIDE FOR YOUR ANSWERS Ma.Science and Engineering Framework 2006

  14. Yes it works Yes it meets our expectations Loosen the gears to not have the gears jam and have something feed the rope in straight Yes Maybe Yes It will be taken apart

  15. Step 7 Communicate the solution(s) Provide the YouTube link of your video that shows how your robot meets the challenge. YouTube video link : http://www.youtube.com/watch?v=PDlaAdLKRE4 Ma.Science and Engineering Framework 2006

  16. Redesign Overhaul the solution(s) based on information gathered during testing and self-assessment activity. I would use wheels instead of gears because wheels can create a variable of tensions that would be easier o work with than gears Ma.Science and Engineering Framework 2006
