In our study, we developed AED Gripping System for AED transport UAV in order to deliver quickly to remote places. This system is structured by grippers and a gripping determination system. We introduced Permanent Electromagnets as gripper. The gripping determination system is necessary to confirm that the AED is delivered at the destination, because AED transport UAV flies to remote places which the pilot cannot see the UAV. We developed a new gripping determination system which use the difference of convergence time of counter-electromotive force between gripping or not. We conducted flight experiments and confirmed that the AED Gripping System do not drop the AED accidentally and can confirm gripping status during flight.

This paper describes a real-time human tracking system by audio-visual integrtation for the humanoid <I>SIG</I>. An essential idea for real-time and robust tracking is hierarchical integration of multi-modal information. The system creates three kinds of streams - auditory, visual and associated streams. An auditory stream with sound source direction is formed as temporal series of events from audition module which localizes multiple sound sources and cancels motor noise from a pair of microphones. A visual stream with a face ID and its 3D-position is formed as temporal series of events from vision module by combining face detection, face identification and face localization by stereo vision. Auditory and visual streams are associated into an associated stream, a higher level representation according to their proximity. Because the associated stream disambiguates parcially missing information in auditory or visual streams, &ldquo;focus-of-attention&rdquo; control of <I>SIG</I> works well enough to robust human tracking. These processes are executed in real-time with the delay of 200 msec using off-the-shelf PCs distributed via TCP/IP. As a result, robust human tracking is attained even when the person is visually occluded and simultaneous speeches occur.

Seabed mineral resources were found on the bottom of the ocean. To utilize these resources, it is necessary to collect and analyze samples. Therefore, we intend to develop a seafloor robotic explorer that can excavate and sample the seafloor soil. In a previous study, we developed a drilling robot and experimentally demonstrated the ability of this robot to produce curved boreholes with a turning radius of 1,670[mm], and a depth of 613[mm] in land environment. However, an underwater excavation has not been successful. It is necessary to improve the gripping torque and to reduce the drilling resistance for underwater excavation. In this paper, we present a propulsion unit with the setae that imitates an earthworm's setae. As a result, the drilling robot succeeded in drilling into the ground while underwater. In addition, we aim to reduce the drilling resistance. We adjusted the penetration speed and the rotational speed of the drilling robot based on the drilling properties of underwater ground. We also consider the shape of the earth auger to reduce the drilling resistance. As a result, we succeeded in reducing the drilling resistance, which both lowered the excavation energy by 39.2% and reduced the completion time.

A high-fidelity attitude estimation technique is proposed for mobile robots which move irregularly in wide space, where heterogeneous inertial sensors are combined in a complementary way in the frequency domain. While the working frequency ranges of each sensor are not necessarily complementary, inverse models of them compensate the sensor dynamics and enlarge their effective working ranges. The problems to be addressed are that the sensor dynamics displays a highly nonlinear property in the case of 3D rotation, and, even if it is approximated by a linear system, the inverse models of them tend to be non-proper and unstable. An idea is to decouple it into the dynamics compensation part approximated by a linear transfer function and the strictly nonlinear coordinate transformation part. By inserting the designed filter before the coordinate transformation, the total transfer function is guaranteed to become proper and stable. Particularly, the differential operator of a high-pass filter cancels the integral operator included in the dynamics compensation of the rate gyroscope, which causes instability.

The recognition of indicated objects by interacting people is an essential function for robots that act in daily environments. However, due to ambiguous references by them, accurate recognition of indicated objects have difficulties for the robots. For example, people sometimes use the words which did not contain in the robots' databases, or they did not use enough words to identify the object. Therefore, to improve recognition accuracy, we must decrease such ambiguity of indicating behaviors of people. For this purpose, we experimentally compared two kinds of interaction strategies to decrease the ambiguity: explicitly providing requests to people about how to refer to objects, or implicitly aligning with people's indicating behaviors. The experimental results showed that participants evaluated the implicit strategy to be more natural than the explicit strategy, and the recognition performances of the two strategies were not significantly different.

This paper presents an effective 3D measurement method from the inside of large structures such as railway vehicles, elevators, and escalators. In our proposed method, images are captured by a moving measurement device, which is composed of a ring laser and a camera, from the inside of the target object. Structures of the target are reconstructed from these images by integrating cross-section shapes, obtained by the light-section method, into unified coordinate by pose changes estimated by Structure from Motion (SfM). We focus on the method to extract information necessary for the light-section method and SfM from the captured images which contain both laser light and texture information. A color filter used in the proposed method enables to extract areas irradiated by the laser for the light-section method. Further, a new block matching technique is introduced to avoid the influence of the laser light, which causes to detect wrong corresponding points. In experiments, we confirmed the validity of the proposed 3D measurement method.

A passive dynamic walking robot can walk down a gentle slope naturally without any actuator or controller, only by potential energy. Therefore, it is thought that the principle of walking exists in this phenomenon. By current researches, the passive dynamic walking has been confirmed for two and four. However, it seems that it is also important to study passive dynamic walking for more than 6 legs because there are many creatures that have more than 6 legs. In this research, a passive dynamic walking robot with more than six legs was analyzed by a simulator. As a result, it was confirmed that passive dynamic walking even for 20 legs could be achieved. Furthermore, its gait could be changed by changing the body structure. In addition, the differences of stability depend on the number of legs resulted, and this differences disappeared by changing the position of the pitch spin parts. Moreover, its stability was very high, so it could walk on the contoured ground.

When a humanoid robot works with a human, it is needed for the robot to pass and receive objects. The robot has to detect that the laden objects are operated by the human on the whole body in object passing tasks. It is important that the robot detects not only push but shear generated by pulling action and twist generated by rotating action for the robot to detect human operations. In this paper, we dispersedly arranged 347 multi-axis soft tactile sensors to a humanoid robot. The multi-axis soft tactile sensors are small muti-axis sensors with urethane structure and they can be placed densely on body of a humanoid. We calculate a deformation vector from the deformation of sensor's upper surface using the output of a muti-axis soft tactile sensor. Next, we suggest the method to detect deformation state in contact surface consisting of soft tactile sensors using deformation moment and average of deformation vectors in the contact surface. Finally, we confirmed the usefulness of the fullbody tactile sensor cover and contact state detector by object passing experiment between a human and a robot.
