Comments from Other Students in the Class (indicate date of comments and if via email or in person)
From In-Person Feedback after Design Proposal Presentation, Thursday, 04/13/17
Keep in mind that one cannot depend on observing a change in current to measure a change in load for a stepper motor (Daniel H.)
Risks and Areas of Concern
Time Risks (e.g. manufacturing of device and receiving shipment of parts on time)
Design Risks (e.g design is prone to high failure rate)
Production Risks (e.g. prototype is impossible to manufacture)
Hardware Failure Risks (e.g. purchased components are incompatible with design or prone to high failure rate)
Project Failure Risks (e.g. design is unable to work or be manufactured within the time-frame limit)
Resources or Information Required but not Available
Mechanical properties of considered motor, encoder, and sensor components
Material properties of considered hardware components (e.g. chassis, friction drive belt, rollers and bearings)
Schedule
