3. 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

4. 1.1Identify 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 Develop solutions Select the best solution Construct a prototype Test and evaluate Communicate the solutions Redesign Ma.Science and Engineering Framework 2006

5. Step 1 Identify the problem Write down the original problem here. Student - Design, build and program a robot to: Successfully climb a rope What constraints have been placed on your team? (Deadlines, resources etc.) We can use all of the items in our kit Ma.Science and Engineering Framework 2006

6. Step 2 Research the problem Explore other options via the internet Student: List the internet sites that were helpful. Site 1 mrcrokesrobotics.weebly.com Site 2 http://kelseysrobotics.weebly.com/dc-10-rope-bot.html Site 3 http://adamdasilva1998.weebly.com/rope-climbing-robot.html What did you learn from your research? A Using rubber on the tires to climb the rope would make it slip B Basic designs for our robot C Simpler/lighter is better Ma.Science and Engineering Framework 2006

7. Step 3 Develop solutions BRAINSTORM COLLABORATION Student : Share your ideas with your design team. List your ideas below. 1.Two sets of tires to pull the robot up 2.3 motors squeezed together around the rope 3.NXT block is not attached to motors and hangs down

8. 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 for your response. Ma.Science and Engineering Framework 2006

9. The Somerset Berkley writing rubric will be used for assessment. Student : Skillfully and imaginatively describe what your first prototype will look like. Lauren Marques Our first prototype will have three motors squeezed tightly together around the rope and the NXT block hanging down. We will gear up to add more power I LOVE SHARKS and strength to the robot. To add compression to the wheels to keep a tight grip on the rope, we secured a hair elastic around the three motors. Since our first prototype did not work, we decided to used two motors with the two tires (without the rubber pieces) and tie the hair elastic there.

10. Ashley Frank: For our first prototype, we will incorporate all three of our motors at the top of robot. They will all be squeezed together with tires attached so the rope will just feed through. We will have the body of the NXT just hang from the three motors. If the motors are squeezed together tight enough, the robot should be able to pull itself up the rope efficiently. If not, we will just cross 2 motors with two tires and have the robot pull itself up like that.

11. Miranda C Our prototype had 3 different motors that squeezed together to cause friction on the rope. We had the robot itself hanging and the motors climbed the rope. This prototype ultimately failed. So then we created a robot with two motors that squeezed tightly together and the NXT robot hung down and it was a success.

12. Step 5 Construct a prototype Build a robot with your NXT lego kit Create a computer program for your robot. Ma.Science and Engineering Framework 2006 Use the next slide(s) for the digital pictures of your prototypes and computer programs.

14. Step 6 Test and Evaluate the solution(s) 1.Does your robot work? Yes 2.Did it perform as expected? Yes 3.What changes are necessary for the robot and the program? We had to Put a hair elastic around the two motors 1.Does it meet the original design constraints? Yes 2.Is it safe? Yes 3.Lab work- Modify your robot project and use the next slide to post a picture of your improved robot project. Ma.Science and Engineering Framework 2006

16. Step 7 Communicate the solution(s) Ma.Science and Engineering Framework 2006 Provide the YouTube link of your video that shows how your robot meets the challenge. YouTube video link : http://www.youtube.com/watch?v=GjeRm FILbq8

17. Redesign Overhaul the solution(s) based on information gathered during testing and self-assessment activity. Ma.Science and Engineering Framework 2006

18. Demonstrate the ability to use technology for research, critical thinking, problem solving, decision making, communication, collaboration, creativity, and innovation.
