Computer Science doctoral candidate Katherine Tsui demonstrates "Halo", a prototype robotic arm that she has designed at the UMass Lowell Robotics Lab to help people with physical disabilities reach for objects on a table or shelf. Halo uses tiny webcams mounted over the arm and on the gripper to display the desired object on a flat screen monitor. The operator simply touches the screen to select the object, and the arm then autonomously retrieves the object and brings it to the operator. The project is funded through a research grant awarded to Prof. Holly Yanco from the National Science Foundation (NSF).
