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 The problem that we face is making our robot able to compete in the dc 6 challenge can bot. We need to make our robot be able to find three cans inside the circle and be able to push them out without leaving the circle itself. 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 http://www.education.rec.ri.cmu.edu/previews/robot_c_products/teaching_rc_le go_v2_preview/sensing/forwarduntildark/documents/Sensing_Forwarduntildark. pdf Site 2 http://www.robotc.net/NaturalLanguage/pdf/nxt/light%20sensor%20rev%202.pd f Site 3 http://www.rocwnc.org/Beginning_NXT_Programming_Workshop.pdf What did you learn from your research? A The way the light sensor works B learned about gear trains C how to face the sensor so it works best 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.The sensor facing down in from of the wheels 2.Bulldozer design for the robot while pushing it 3. geared down so it will go slower and not break

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. Our first prototype for can bot will four wheels, in which were the two back wheels are connected. In the front we will have out light sensor pointing downwards so it will stop the robot before it leaves the circle. The robot will be geared down so it will go slower and not be so fast it leaves the circle before it can recognize the darkness and stop.

10. 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.

11. 1st Prototype picture and computer program Step 5 evidence

12. Step 6 Test and Evaluate the solution(s) 1.Does your robot work? Yes 2.Did it perform as expected? No 3.What changes are necessary for the robot and the program? The robot works but he program is wrong so we need to fix the program. 4.Does it meet the original design constraints? Yes 5.Is it safe? Yes 6.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

13. 1 st modified prototype picture and computer program Step 6 evidence

14. 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=jgjH4177_tI

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