2. Somerset Berkley Regional High School Robotics Engineering with Lab View

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 Design, build, and control a robot with a cellular phone to: Battle another robot to push it out of a ring or disable within a two minute time span. Ma. Science and Engineering Framework 2006

6. Step 2 Research the problem Student: List the internet sites that were helpful. Site 1 http://nxtprograms.com/mini_sumo/index.html Site 2 http://mrcrokesrobotics.weebly.com/all-about-gears.html Site 3 http://www.societyofrobots.com/robot_sumo.shtml What did you learn from your research? A Ramp attachment to front. B Gear down for high power C Wide supporting base to provide support. 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.Wide supporting base to provide us with support. 2.Ramp attachment to flip over opposing robots. 3. A claw mechanism to grab opponents’ wires and knock them over

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 will have certain features to make it very powerful and lead us to the victory in the ring. Our NXT brain will be turned sideways and be angled downward as a ramp. We will also be gearing down our wheels with a 1:2 ratio meaning we will get two times the torque at the cost of half of our speed. We have two unpowered front wheels and two powered back wheels. These back wheels will be spread out wide to give us a strong base.

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, it did not move as well as I liked. 3.What changes are necessary for the robot and the program? We need to make it move better and add a better ramp. 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

14. 2 nd modified prototype picture and computer program Step 6 evidence

15. 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=iejY5TnegeU

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

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