Expressive Hardware Modules
Quori is a low-cost socially interactive robot platform comprised of an upper-body humanoid with a rear projection head and two gesturing arms on a mobile base. Updates for the robot’s hardware are presented on this page. Each component is designed to be modular, expandable, customizable, and affordable.
To maximize flexibility, both in the style and apparent motion of the robot’s head, we exploited the relatively recent availability of low-cost portable projectors in a retro-projected animated face
Omnidirectional Mobile Base
The base measures 19 inches in diameter and 8 inches in height and complies with the 2010 Americans with Disabilities Act. The max speeds the base is able to achieve are 0.8m/s in a straight line and 180 degrees per second with the turret.
Gestures are a key part of natural communication in social interaction. Our arm design is low-cost, modular, safe, and expandable. Our current version of the arm has two degrees of freedom that mimic the ball joint of a human shoulder.
