Creating believable androids is not just a technological feat, but an artistic one. The Yume Project addresses the challenge of creating lifelike androids by developing complex character. The authors demonstrate the unique perspectives artists can bring to the humanoid robot design process through costume, character, and story development. The authors hope to show that it is a focus on believability rather than realism that is needed to advance the field of humanoid robotics.

We present a technique for estimating the 6DOF pose of a PTZ camera by tracking a single moving target in the image with known 3D position. This is useful in situations where it is not practical to measure the camera pose directly. Our application domain is estimating the pose of a PTZ camera so that it can be used for automated GPS-based tracking and filming of UAV flight trials. We present results which show the technique is able to localize a PTZ after a short vision-tracked flight, and that the estimated pose is sufficiently accurate for the PTZ to then actively track a UAV based on GPS position data.

This paper reports on some of the robotic platforms used in the project AUROSO which investigates the use of robots as educationally useful interventions to improve social interactions for individuals with Autism Spectrum Disorders (ASD). Our approach to treatment uses an educational intervention based on Socially Assistive robotics (SAR), the DIR/Floortime intervention model and social script/stories. Requirements are established and a variety of robotic models/platforms were investigated as to the feasibility of an economical, practical and efficient means of helping teach social skills to individuals with ASD for use by teachers, families, service providers and other community organizations.

The ongoing development of robotics against the background of a decreasing number of care personnel raises the question which contribution robotics could have to rationalize and maintain, or even improve the quality of care. A systematic review was conducted to assess the effects and consequences of the interaction between socially assistive robots and elderly, in published literature. We searched in CINAHL, MEDLINE, The Cochrane Library, BIOMED, PUBMED, PsycINFO, EMBASE and the IEEE Digital Library. In addition, articles were selected through free Internet search and from conference proceedings. Studies have been found reporting positive effects of companion type robots on (socio)psychological level and physiological level. However, the scientific value of the evidence is limited due to the fact that most research is done in Japan with a small set of robots, with small sample sets and with mostly an explorative approach.

In this paper, a novel composite 6-DOF parallel robot is introduced. Two independent components are included in this new mechanism. One is a planar 3-RPR mechanism, the other is a spatial 3-UPS-1-PU mechanism. The planar mechanism provides translations along the x and y axes and rotation around the z axis. As a complement, the 3-UPS-1-PU mechanism provides translation along the z axis and rotations around the x and y axis. These two mechanisms are combined using a serial connection. Different combinations of these two mechanism are proposed in this paper.

This paper presents a nanomanipulation system for operation inside scanning electron microscopes (SEM). The system is small in size, capable of being mounted onto and demounted from an SEM through the specimen exchange chamber without breaking the high vacuum of the SEM. This advance eliminates frequent opening of the high-vacuum chamber, thus, incurs less contamination to the SEM, avoids lengthy pumping, and significantly eases the exchange of end-effectors (e. g., nano probes and grippers). The system consists of two independent 3-DOF Cartesian nanomanipulators based on piezo motors and piezo actuators. High-resolution optical encoders are integrated into the nanomanipulators to provide position feedback for closed-loop control. A look-then-move control system and a contact detection algorithm are implemented for horizontal and vertical nanopositioning. The system design, system characterization details, and system performance are described.

In this paper, we focus on how to control the robot end-effector to track an object, meanwhile, to approach it with a suitable posture for grasping. We named it "Approaching Visual Servoing". A proposed hand & eye-vergence dual control system is used to perform Approaching Visual Servoing, aiming at quick eye-tracking and stable hand servoing and approaching. This idea stems from hammerhead shark whose eyes turn to gaze at the target prey to be suited to triangulation, enhancing the ability to measure precisely the distance to the prey for catching it. This animal's visual tracking includes motion control by visual servoing and triangular eye vergence. Moreover, a 3-D pose tracking method that combines "1-Step GA (genetic algorithm)" and hand-motion feedforword compensation is proposed. Our approach differs from known tracking methods using optimization based on Taylor expansion, for it allows the proposed method not to be annoyed by how to sneak out of local minima. A convergence in time domain -whether the 3-D pose tracking error decrease to zero in a successively input images by video rate -, is discussed and verified through Lyapunov method. Both Lyapunouv-stable pose tracking and Approaching Visual Servoing are confirmed by experiments using a 7-link manipulator installed with two mobile cameras.
