Visual Control Interface of a Wheelchair Mounted Robotic Arm for Cognitively Impaired Wheelchair Users
The Exact Dynamics' Manus ARM, a 6+2 degree of freedom wheelchair mounted robot arm, is able to function in unstructured environments. However, it is awkwardly controlled through a menu system using a keypad, a joystick or a single switch. These controls are not intuitive or natural because they require a high level of cognitive awareness. Also, the input devices may not correlate well to the user’s physical and cognitive abilities.
Our research investigates visual control of a robot arm. We leverage all of the Manus ARM’s benefits while eliminating its weaknesses. Our vision-based system draws inspiration from people’s innate abilities to see and touch. Because the wheelchair occupant is collocated with the ARM, the occupant's view is the same as a camera mounted over the ARM's shoulder. The occupant selects the desired object using from a flexible interface and touch screen or mouse-emulating joystick. Our goal is to allow the occupant to acquire the object by unfolding the ARM, then reaching and grasping the object in a manner emulating human kinematics. This human-in-the-loop control will provide simpler and effective interaction. Read more >>
Situation awareness (SA) is critical to successfully operate an unmanned vehicle. Since 2003, we have studied multiple systems designed for USAR. We have both designed evaluation methods and produced design guidelines for HRI. Read more >>
A low cost robot arm system is developed that will increase a person’s accessibility to indoor spaces by unlatching door knobs and door handles. Implemented is a minimized arm configuration for use with a wheelchair or mobile platform and a gripper design that utilizes only a single motor to turn door knobs and door handles. This proof of concept prototype demonstrates how an arm with many degrees of freedom is not required if we target the expectations for its use. Read more >>
The VGTV is a tele-operated, tethered robot. It is capable of changing its shape, depth rated to 100 feet, and equipped with a color zoom camera, two-way audio, and lights. Sensors and small equipment can be carried by the VGTV into search areas. Our VGTV was used in Biloxi, Mississippi after Hurricane Katrina by Florida Task Force Three. Rescuers were able to search unsafe structures and experience a first person view from the robot. Read more >>
Computer Vision: Phission
Phission is a concurrent cross-platform, multiple language vision system software development kit (SDK). The SDK constructs a processing sub-system for computer vision applications. Phission abstracts low-level image capture and display primitives, which allows researchers to focus on their primary work.
Consisting of an electric wheelchair outfitted with a computer and sensors and a Macintosh Powerbook, this robot can travel semi-autonomously in an indoor environment. This allows the user to issue general directional commands and to rely upon the robot to carry out the low level routines such as object avoidance and wall following. Read more >>
Serial Sense allows anyone to interface simple digital and analog sensors to a computer. It also gives you the ability to control custom hardware circuits with the digital outputs. This was designed to expand the sensor capabilities of ActivMedia's Pioneer robots. However, it will work with any PC that has a serial port.
Pyro stands for Python Robotics. The goal of the project is to provide a programming environment for easily exploring advanced topics in artificial intelligence and robotics without having to worry about the low-level details of the underlying hardware.
