P10010: Motion Tracking Sensor/public/Meeting Agendas/
Week 9- Friday Feb 12th (Detailed Design Review)
DDR Presentation Feedback
- Schematics/drawings for sensors? Circuitry?
- Include shipping costs in BOM estimates
- Check with Dr. DeBartolo before buying & with labs for available equipment
- Forearm/wrist robot- Dr. Lamkin Kennard? Follow up
- Possible to loan test spine fixture for 1 week rather than having to visit Nazareth?
- Way to measure translation-relative motion?
- Magnetic feedback- issue for sensors?
- Machine shop- have protractors/measuring devices?
- Sacrifice a few cheap sensors to test for
- Dr. DeBartolo is willing to give us $50 for these purposes
- Need to test ALL sensors- don't buy it if you won't use it!
From P10011 Presentation
- Make sure our units match theirs!
- Modular PSU concept?
- They will test the ATOMIC IMU size- if they deem it to be too big, we don't have to worry about evaluating it
From Rubric Feedback
- electrical: don't buy wire and solder if you can get it here, but DO include it in the real cost of the project.
- Mechanical: raw materials are priced based on McMaster-Carr and team realizes that those costs are high.
- Include shipping costs in final BOM mechanical drawings good - difficult to validate all three angular DOF independently.
- CE: not enough analysis on sybsystem/component interconnects - specific I/O port bit mappings to control inputs and data paths
- electrical: well thought out. I'm curious about (1) interference, (2) how 3-axis tilt sensors work without third dimension board, (3) means of collecting data - frequency?
- CE: Good *analysis* but no feasibility *measurements* have been made yet. well done, but still not clear on whether you can write a text file and convert it to C3D later. That still shows as a risk.
- well-documented and explained., Include some shock or impact testing - willing to spend $50 or so to make sure you're not going to overload an accelerometer
- FYI: pitch, ROLL, yaw.
