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 Student – student directed project: design a robot that keeps its balance on two wheels, like a segway. 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 1Youtube.com Site 2 nxtprograms.com Site 3 active-robots.com What did you learn from your research? A we can only use ev3 robots B balancing the robot is important C need a gyro sensor 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.Need a perfectly balanced robotic 2.Need the correct gyro boy program 3. Need a stabilizing bar for the first prototype

8. Step 4 Select the best Possible solution(s) Student: The key to this design is in the program. The program has to be perfect and use a gyro sensor to properly work. The bot also has to be perfectly weighted and balanced. Ma.Science and Engineering Framework 2006

9. The Somerset Berkley writing rubric will be used for assessment. Student : Our first prototype has 4 wheels underneath the actual nxt itself. It has two motors on each side that spin to keep it balanced. The gyro sensor is placed near the top of the bot and is held upright, level to the ground.

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. Step 5 evidence

12. Step 6 Test and Evaluate the solution(s) 1.Does your robot work? yes 2.Did it perform as expected? Needs minor adjustments 3.What changes are necessary for the robot and the program? Balance changes 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. 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. http://www.youtube.com/watch?v=PzF7PFDAnoI& list=UUI1cRL8MafqX4qKSsVb_Uzg http://www.youtube.com/watch?v=PzF7PFDAnoI& list=UUI1cRL8MafqX4qKSsVb_Uzg YouTube video link : http://www.youtube.com/watch?v=PzF7PFDAnoI& list=UUI1cRL8MafqX4qKSsVb_Uzg http://www.youtube.com/watch?v=PzF7PFDAnoI& list=UUI1cRL8MafqX4qKSsVb_Uzg

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