HERL is currently working with assistive robotic manipulators such as the iArm, which is used on PerMMA, and the JACO arm (pictured right), as used on KitchenBot.
One project uses a camera with computer vision and manipulation software to identify an object, automatically grasp it, and move it to the proximity of the user. For example, a can of soda can be recognized, and, even if there are other objects in the way, can be brought close enough for a user with limited upper body mobility to drink from. To evaluate the manipulator, we created a standardized performance evaluation tool. The tool, which features common daily objects and tasks such as buttons, toggle switches, handles, and knobs that can be grasped and/or manipulated. Our goal is that this will become the standard in evaluating robotic manipulators.
HERL researchers are also at the forefront of brain-computer interface technology work. After implanting sensors in volunteers’ brains, they were able to skillfully manipulate a specially-designed robotic arm.
