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

• • From meeting at Rady Children's, in-person between Dr. Skalsky, Max & Parents 5/29

    • Control method needs to be changed

    • Make entire device portable - put battery pack on his back as his core is strong

    • Reduce sizing of gloves

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

• • Consider machining joint

    • Will prioritize this last as prototype has to be appealing for Max to use

  • Include a battery life display

    • Incorporated battery voltage checker which will notify user if device requires charging

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

Risks and Areas of Concern

• • Electronics placement in pouch

  • Pouch placement

  • Glove sizing

  • Control method - need to change to flex sensor which will significantly improve Max's ability to control his arm
