Intro to Seamobile Engineering Grading and Class Policies:
Policies
- Show up to class prepared (notebook & pencil & calculator)
- During lectures or class discussions, only one person talks at a time
- Raise your hand when you want to ask a question
- Treat your peers with respect at all times
- If Mr. Rhine asks you to do something, please do it! (e.g., if you are asked to move to a different desk or to team up with another group, please comply!)
- If you are absent, please ask for missed handouts and copy notes from a peer (ask a peer who takes good notes). Most of what we do is posted on the web site.
- If you want to take photos or videoclips to post on the web site, please ask Mr. Rhine for permission and make sure the people in the photo give you permission as well.
Grading (subject to change)
Class Participation & Conduct (30 points)
- Lose one point for missing notebook when you come to class
- Lose one or more points for poor class conduct
Neat, Organized Notebook (30 points)
- All pages in chronological order
- Name, date & cohort on top of each page
Classwork = (275 points) (subject to change)
Seamobile Design & Build (250 points)
- Design and build first frame prototype (50 points)
- Design Requirements: must be symmetric and 3D and stable
- Design Constraints: Must fit into specified size limit (ask!)
- Draw a nice sketch in your notebook and identify where 3 motors will be positioned. Explain how it will drive forward, backward, left turn, right turn, move up & down
- Make first frame neutrally buoyant and stable (50 points)
- Add motors and adjust for buoyancy & stability (50 points)
- Test drive & record observations & conclustions in your notebook (50 points)
- Make note of how your seamobile "drives" in the water.
- Is it stable?
- Is it really neutrally buoyant? (adjust if necessary)
- How fast is it compared to others?
- Does it drive "straight & level" when L + R motors are forward? Or does it pitch up or down? Why?
- Does it drive "straight" up & down when C motor is used? Or does it "pitch"? Why?
- Other observations??
- Redesign your seamobile (50 points)
- Make changes based on your observations from your prototype
- Re-establish neutral buoyancy & make sure your design is stable
- Take it out for a test drive and record observations & conclusions in your notebook
- What changes did you make and why?
- Is your redesign better? Explain!
