Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Weekly Meeting with Dr.Goldberg (In person, 4/24)

    • A shorter handle (closer to cart) would be more ideal from a spacial point of view.

    • If possible, having releases for legs on handle would be ideal.

    • When prototype is ready, doing a consumer feedback survey would be useful.

    • Bring leg prototypes to meeting next week

    • Personal reimbursements will be in the form of a personal check to each member at the end of the quarter/project.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Weekly Meeting with Instructor (In person, 4/20)

    • Try to limit back leg design to one release, so one hand could be used to hold cart.

      • Consider garage door mechanism for sliding of back legs

      • Consider angling back of cart, so that heavy items will slide to the front of cart and prevent it from tipping backwards.

    • Remember to read over each others chapters of the report.

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Feedback from Design Proposal Presentation:

    • Animations would be helpful in understanding concepts

    • Consider addition of a detachable bumper protection plate (https://www.bumperbully.com/Bully_Gallery_Pics/Bumper_Bully_19.jpg)

    • Try to avoid having to manually engage two pins when folding

    • Consider optimizing with addition of damping and tipping test.
