Justin Martinez a Bishop Gorman senior works on improving his 3d gauntlet model. The gauntlet is a part of the 3d printed "robo hand" that attaches to the user's forearm. To help improve this design, he is modifying his original model to accommodate the addition of a 9 volt battery, a switch and a servo. The hope is to add a mechanical advantage when the user needs to grip an object for an extended period of time.
