In this paper we present a public dataset to evaluate trackers used for human and robot manipulation tasks. For these tasks both high DOF motion and high accuracy is needed. We describe in detail, both the process of recording the sequences and how ground truth data was generated for the videos. The videos are tagged with challenges that a tracker would face while tracking the object. As an initial example, we evaluate the performance of six published trackers [5], [11], [12], [13], [15], [6] and analyse their result. We describe a new evaluation metric to test sensitivity of trackers to speed.A total of 100 annotated and tagged sequences are reported. All the videos, ground truth data, original implementation of trackers and evaluation scripts are made publicly available on the website so others can extend the results on their trackers and evaluation.
We present a human robot interface (HRI) for semiautonomous 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
