Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Limit DOF of mount (1 Pivot and motor location adjustment)

  • Submit quote for purchase

  • Ok to reduce speed requirement

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Consider increasing gear box gear ratio

  • Needs more motor justification

  • Increase background info clarity & justification of design

  • Look into rigid coupling>Stock drive>clamps>shigley
