Two arms are better than one: A behavior based control system for assistive bimanual manipulation

Abstract

Robots that work alongside people in their homes and workplaces could potentially extend the time an elderly person can live at home, provide physical assistance to a worker on an assembly line, or help with household chores. Human environments present special challenges for robot manipulation, since they are complex, dynamic, uncontrolled, and difficult to perceive reliably. For tasks that involve two handheld objects, the use of two arms can help overcome these challenges. With bimanual manipulation, a robot can simultaneously control two handheld objects in order to better perceive key features, control the objects with respect to one another, and interact with the user. © 2008 Springer-Verlag Berlin Heidelberg.
