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
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 Redesign problem Communicate the solutions Test and evaluate Ma. Science and Engineering Framework 2006 Develop solutions Construct a prototype Select the best solution
Step 1 Identify the problem Write down the original problem here. The problem was to think of and create any robot in our wildest dreams. Ma. Science and Engineering Framework 2006
Step 2 Research the problem Explore other options via the internet Student: Nxtrobotics. com Google Images mrcrokesrobotics. weebly. com What did you learn from your research? I learned the physics of launching a Lego piece Ma. Science and Engineering Framework 2006
Step 3 Develop solutions BRAINSTORM COLLABORATION Student : Share your ideas with your design team. List your ideas below. 1. Lego dolphin 2. Segway 3. Lego Launcher Ma. Science and Engineering Framework 2006
Step 4 Select the best Possible solution(s) Student: We decided on creating a robot that could shoot Lego pieces. We thought this would be a fun project. Ma. Science and Engineering Framework 2006
The Somerset Berkley writing rubric will be used for assessment. Student : The robot will look some what complicated but it’s mechanisms will be very simple. There will be a motor with a big to small gear ratio. Attached to the motor will be a long axle piece that will rotate at high speeds due to the gearing. This piece is what will launch the Lego piece. There will be a loader adjacent to the spinning axle piece and it will feed pieces so it can continuously shoot. It will also have a long piece protruding out the front so the small Lego pieces can slide on and it can shoot accurately. There will be a trigger on the back so we can manually choose when to shoot the pieces. We predict to launch the pieces about 5 -6 feet. The program will be a true false case structure. When the program is true the button will be pressed and the pieces will be launched. When it’s false the button will not be pressed and it will do nothing. That is all that is going to go into this Lego Launcher.
Step 5 Construct a prototype Build a robot with your NXT lego kit Create a computer program for your robot. Use the next slide(s) for the digital pictures of your prototypes and computer programs. Ma. Science and Engineering Framework 2006
Step 5 evidence 1 st Prototype picture and computer program
Step 6 Test and Evaluate the solution(s) Our robot worked better than we expected and it shot the pieces very well. We didn’t have to make any changes to the original design. We decided to amp it up a little and put wheels on the robot. We wanted to be able to drive it around and launch the pieces. Ma. Science and Engineering Framework 2006
Step 6 evidence 1 st modified prototype picture and computer program
Step 6 evidence 2 nd modified prototype picture and computer program We did not have a 2 modified prototype
3 rd modified prototype picture and computer program We did not have a third modified prototype Add additional slides as necessary
Step 7 Communicate the solution(s) Provide the You. Tube link of your video that shows how your robot meets the challenge. http: //www. youtube. com/watch? v=NV 6 GBYRVt. HU Ma. Science and Engineering Framework 2006
Redesign Overhaul the solution(s) based on information gathered during testing and self-assessment activity. Ma. Science and Engineering Framework 2006
