1000 Trials: An empirically validated end effector that robustly grasps objects from the floor
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2009-05)Unstructured, human environments present great challenges and opportunities for robotic manipulation and grasping. Robots that reliably grasp household objects with unknown or uncertain properties would be especially useful, ... -
Autonomous Active Learning of Task-Relevant Features for Mobile Manipulation
(Georgia Institute of Technology, 2011)We present an active learning approach that enables a mobile manipulator to autonomously learn task-relevant features. For a given behavior, our system trains a Support Vector Machine (SVM) that predicts the 3D locations ... -
Autonomously learning to visually detect where manipulation will succeed
(Georgia Institute of TechnologySpringer Verlag, 2013-09)Visual features can help predict if a manipulation behavior will succeed at a given location. For example, the success of a behavior that flips light switches depends on the location of the switch. We present methods that ... -
Behavior-Based Door Opening with Equilibrium Point Control
(Georgia Institute of Technology, 2009-06)Within this paper we present a set of behaviors that enable a mobile manipulator to reliably open a variety of doors. After a user designates a location within 20cm of the door handle, the robot autonomously locates the ... -
Behaviors for Robust Door Opening and Doorway Traversal with a Force-Sensing Mobile Manipulator
(Georgia Institute of Technology, 2008-06)Fully autonomous robots will often need to open doors and traverse doorways in order to freely operate within human environments, and assistive robots that open doors on command would potentially benefit the motor impaired. ... -
Bio-inspired Assistive Robotics: Service Dogs as a Model for Human-Robot Interaction and Mobile Manipulation
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-10)Service dogs have successfully provided assistance to thousands of motor-impaired people worldwide. As a step towards the creation of robots that provide comparable assistance, we present a biologically inspired robot ... -
A Clickable World: Behavior Selection Through Pointing and Context for Mobile Manipulation
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2008-09)We present a new behavior selection system for human-robot interaction that maps virtual buttons overlaid on the physical environment to the robotpsilas behaviors, thereby creating a clickable world. The user clicks on a ... -
The complex structure of simple devices: A survey of trajectories and forces that open doors and drawers
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2010-09)Instrumental activities of daily living (IADLs) involve physical interactions with diverse mechanical systems found within human environments. In this paper, we describe our efforts to capture the everyday mechanics of ... -
Dusty: A Teleoperated Assistive Mobile Manipulator that Retrieves Objects from the Floor
(Georgia Institute of Technology, 2010-06)Retrieval of dropped objects has consistently been ranked as a high priority task for assistive robots. We have previously presented a dustpan-inspired end effector capable of robustly grasping objects from the floor. In ... -
Effects of Force Feedback and Arm Compliance on Teleoperation for a Hygiene Task,
(Georgia Institute of TechnologySpringer Berlin / Heidelberg, 2010-07)Teleoperated assistive robots with compliant arms may be well-suited to tasks that require contact with people and operation within human environments. However, little is known about the effects of force feedback and ... -
EL-E: An Assistive Mobile Manipulator that Autonomously Fetches Objects from Flat Surfaces
(Georgia Institute of Technology, 2008-03-12)Objects within human environments are usually found on flat surfaces that are orthogonal to gravity, such as floors, tables, and shelves. We first present a new assistive robot that is explicitly designed to take advantage ... -
EL-E: An Assistive Mobile Manipulator that Autonomously Fetches Objects from Flat Surfaces
(Georgia Institute of TechnologySpringer Netherlands, 2010-01-01)Assistive mobile robots that autonomously manipulate objects within everyday settings have the potential to improve the lives of the elderly, injured, and disabled. Within this paper, we present the most recent version of ... -
Fast Reaching in Clutter While Regulating Forces Using Model Predictive Control
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-10)Moving a robot arm quickly in cluttered and unmodeled workspaces can be difficult because of the inherent risk of high impact forces. Additionally, compliance by itself is not enough to limit contact forces due to ... -
Finding and Navigating to Household Objects with UHF RFID Tags by Optimizing RF Signal Strength
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-09)We address the challenge of finding and navigating to an object with an attached ultra-high frequency radio- frequency identification (UHF RFID) tag. With current off-the- shelf technology, one can affix ... -
