2. Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] Recently, NASA’s fledgling Spaceploration program launched its first in a series of state-of-the-art space exploration vehicles. These one of a kind ships are the world’s finest reusable, multiple-flight, personnel carrying launch vehicles. However, a tragedy has befallen the crew of the first of these ships, Orbit. Only minutes after launch, the Orbit spacecraft, traveling at nearly 3000 miles per hour, collided with a high-flying bird. The resultant damage has made it impossible for Orbit to return to Earth safely. It is the mission of NASA’s Extreme Circumstances Team (ECT) to devise a manipulator arm capable of repairing the damaged Orbit aircraft before time runs out. Can a robotic arm that will fix the damage be able to be built in the next week?

6. Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] Design and implementation are critical components of every part of our technical world. In this assignment you were given a problem with certain constraints (limitations) on the solution. Every design challenge in the real world involves some sort of constraint (strength, weight, cost, manufacturability, etc). This assignment was written to help prepare you for real-world design problems. You built skills in the areas of conceptual design, supplier research and distribution, as well as reporting.

9. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This lesson was designed as an assignment for Colorado State University’s Education 331 class. The purpose of this lesson to merge a science-based class learning the basics of forces and stresses with a “real-life” design problem. This lesson will provide insight into the world of engineering while teaching students to apply their physics knowledge to create a useful product. In this lesson, a fictional NASA spacecraft , the “Orbit,” has hit a bird during launch. Because there is too much damage to the spacecraft for safe re-entry, the students must design a robotic arm that will be able to fix the damaged spacecraft. Evaluation Teacher Script Conclusion

10. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This lesson is designed for an advanced 11 th to 12 th grade science or technology class. Prior knowledge of basic material mechanics is critical for this lesson. Conceptual understanding of torque, moment, shear stress, and bending stress is critical. Additionally, basic knowledge of material mechanics equations would be beneficial. Evaluation Teacher Script Conclusion

14. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page The product of this lesson should be a concise (~2 page) report on the material selected for the arms with detailed math showing it will not fail, as well as a motor/gear combo that will output enough torque (~1000Nm) to overcome stated forces. Don’t worry too much about how the gears will mesh with the motor or how the motor will attach to the arms. If students seem to have solved the physics problem and found a solution for parts and materials online that is acceptable, the lesson is a success!
