Meet Yolanda, the robot used for the Human-Robot Interaction research project. Yolanda features custom 3D printed parts which replaced the default hand with an extension that interfaces with two detachable versions of trays.

After removing the hand, calipers were used to get specific measurements for this 3D printed arm extension. The square with a hole through it interfaces directly with Yolanda's arm, where as the end with the square stump interfaces with the changeable trays.

Tray A used in the study. The square cutout, that interfaces with the 3D printed arm extension, is angled to keep the tray level since Yolanda's forearm is angled.

Tray B used in the study. The square cutout, that interfaces with the 3D printed arm extension, is angled to keep the tray level since Yolanda's forearm is angled.
