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 In this challenge we had to create a robot that would successfully climb up a rope and then come back down it. Ma. Science and Engineering Framework 2006

Step 2 Research the problem Explore other options via the internet We didn’t use any internet sites. We just went for it and used a guess and check system of creating a prototype, testing it and then making any necessary improvements. 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. Something that would reel the rope in. The rope could be tied around a tire and as it rotated the rope would gradually collect around the wheel, . 2. A robot with two wheels that would clamp the rope. The wheels without the rubber would pull the robot up the rope and bring it back down again. Ma. Science and Engineering Framework 2006

Step 4 Select the best Possible solution(s) We decided to build the robot with the two wheels that would clamp the rope. We thought this would be a simpler design and we would be able to alter/improve it in more ways than the fishing reel robot. Ma. Science and Engineering Framework 2006

The Somerset Berkley writing rubric will be used for assessment. Our robot will have few parts to it but it will be effective. Two motors will be attached side by side. There will be two wheels without the rubber at the rotating points of the motors. There will be a wall the keeps the rope from falling out of the tires. The power of the motors will be turned up to 100, this will allow the robot to get up the rope. The battery pack will not be attached to the motors. It will be left hanging down below as the robot continues up the rope. It will be dragged up the rope. This is because the parts needed to connect the battery pack will make the robot too heavy. If the robot is too heavy then it will not go up the rope. The idea behind this robot will be to decrease the weight while increasing the power.

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) The first prototype of our robot did not work. It kept slipping down the rope, it didn’t have enough grip. The first modified prototype will have a better barrier to keep the rope into the wheels while making the wheels tighter around the rope. This was a success. Ma. Science and Engineering Framework 2006

Step 7 Communicate the solution(s) Provide the You. Tube link of your video that shows how your robot meets the challenge. You. Tube video link http: //www. youtube. com/watch? v=W_31 e. Fg. RUt. E Ma. Science and Engineering Framework 2006

Redesign If I could redesign the robot I would get the tightness around the rope right on the first try. Ma. Science and Engineering Framework 2006
