• Stores Junkyards
• Go touch some hardware (youll get ideas)
• Robotic parts ? go to a toy store

General comments on Figures
Super-duper Coleman Heater

• Put titles on your figures (easier to reference)
• Label the important things on your figures
• Make sure to cite (even yours)
• Example shown on right

Propane tank
Diffuser
Optional Stand

Critical Function Prototypes

• What makes a good CFP?
• Something youll learn from
• Perhaps a risky design that could reap rewards
• Preferably something physical
• Something non-trivial / non-obvious
• Something that represents about 2 team-weeks
  effort
• Good approach is to list components in design and
  their functions and assess risk associated with
  each
