This paper describes a vacuum gripper that imitates the sucker of the octopus which is useful for the handling of industrial parts. It is difficult to use other sucker type vacuum grippers, but this gripper can adhere to rigid materials since the sucker is flexible. In the present work, we evaluated the effect of a liquid membrane on vacuum suction, since the industrial part often has a liquid membrane...
Snakes are very unique animals that have distinguished motor function adaptable to the most diverse environments in terrestrial animals regardless of their simple cord-shaped body. Revealing the mechanism underlying this distinct locomotion pattern, which is fundamentally different from walking, is significant not only in biological field but also for applications in engineering field. However, it...
For the total knee arthroplasty, we developed the robotic system, such as the cutting feed rate is controlled depending on the hardness of the bone tissue predicted on the basis of the medical image. Since the cutting force is reduced by this system, the displacement of the bone is minimized during the bone cutting process. Therefore it makes a possibility to fix the target bone using “safer” and...
In this paper, we propose stereo vision based visual odometry with an effective feature sampling technique for untextured outdoor environment. In order to extract feature points in untextured condition, we divide an image into some sections and affect suitable processes for each section. This approach can also prevent concentration of feature points, and the influence with a moving object can be reduced...
In this paper, investigate the relation between emotions represented by speech and features included in speech. There are two kinds of approaches in comparing experiment. Firstly, speech data are non-verbal such as white-noise, sine wave and vowel /a:/, so that investigate the relation between emotions and prosodic features only. Secondly, speech data include verbal information such as `ohayou'(hello),...
Complex visual tasks may be tackled with remarkably simple neural architectures generated by a co-evolutionary process of active vision and feature selection. This hypothesis has recently been tested in several robotic applications such as shape discrimination, car driving, indoor/outdoor navigation of a wheeled robot. Here we describe an experiment where this hypothesis is further examined in goal-oriented...
High mobility and large payload capability are important for wall climbing robots. The authors have proposed a new robot system Anchor Climber that could achieve both of these two abilities. This robot system is composed of two or more child units and a parent unit. As child units, wall climbing robots Adhering Mobile Units (AM Units) have been developed by using the technique of internally-balanced...
This article presents a method for cooperative robot actions through multi-stage construction of action intelligence. The intelligent composite motion control is a learning methodology for intelligent robots that gradually realizes complex actions from fundamental motions. It is not easy, however, to obtain the action intelligence of a complex cooperation at once, hence the intelligence is constructed...
