Robotics Engineering with LabView
1. Engineering DesignCentral 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.

Step 1Identify the
problem
Write down the original problem here.Student - We need to make a robot that an drift with an ultrasonic sensor.
What constraints have been placed on your team? Wednesday

Step 2Research the
problem
Explore other options via the internetStudent: List the internet sites that were helpful.Site 1_www.alpcentauri.info/gear_train_example.htmlSite 2_https://www.youtube.com/watch?v=CjIEh_8jml8Site 3 _____________________
What did you learn from your research?A We have a lot of possible gear trains to work fromB That a nxt drift car can actually driftC

Step 3Develop solutions BRAINSTORM
COLLABORATION
Student : Share your ideas with your design team. List your ideas below.
1.A fast nxt car with an ultrasonic sensor
2.A regular nxt car with a sound sensor
3.A fast nxt car with a sound sensor and an ultrasonic sensor
Step 4Select the best
Possible solution(s)
Student: Describe which solution(s) best meet the need orsolve 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
The Somerset Berkley writing rubric will be used for assessment.
Student : Skillfully and imaginatively describe what your firstprototype will look like.
We need to build a fast gear train that isn’t too fast. It should be compact and be able to hold two gear trains that are parallel to each other as well as an ultrasonic sensor. We need to create wheels that have enough friction to propel the car but not a lot of friction so it wont drift.
Step 5Construct a prototype
Build a robot with your NXT lego kitCreate 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.
1st Prototype picture and computer program
Step 5 evidence
Step 6Test and Evaluate
the solution(s)
1. Does your robot work? no2. Did it perform as expected? no3. What changes are necessary for the robot and the program? Lessen
the gear ratio4. Does it meet the original design constraints? yes5. 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.

1st modified prototype picture and computer program
Step 6 evidence
2nd modified prototype picture and computer program
Step 6 evidence
The nxt was the exact same as this without the two extra sensors
3rd modified prototype picture and computer program
Add additional slides as necessary
Step 7Communicate the solution(s)
Ma.Science and Engineering Framework 2006
Provide the YouTube link of your video that showshow your robot meets the challenge.

Redesign
Overhaul the solution(s) based on information gatheredduring testing and self-assessment activity.
Ma.Science and Engineering Framework 2006
• Demonstrate the ability to use technology for research, critical thinking, problem solving, decision making, communication, collaboration, creativity, and innovation.
