Abstract
We present a human robot interface (HRI) for semi-autonomous human-in-the-loop control, that aims to tackle some of the challenges for robotics in unstructured environments. Our HRI lets the user specify desired object alignments in an image editor as geometric overlays on images. The HRI is based on the technique of visual task specification [1], which provides a well studied theoretical framework. Tasks are completed using uncalibrated image-based visual servoing (UVS). Our interface is shown to be effective for a versatile set of tasks that span both coarse and fine manipulation. We complete tasks such as inserting a marker in its cap, inserting a small cube in a shape sorter, grasping a circular lid, following a line, grasping a screw, cutting along a line, picking and placing a box and grasping a cylinder using a Barrett WAM arm and hand.
