In order to create agile locomotion for legged robots, so far various methods have been proposed with the concept of neural circuits, or so-called Central Pattern Generator (CPG) . In contrast to these approaches in which monolithic CPG neural circuits are employed to control locomotion, this paper focus on a polymorphic CPG neural circuit. This allows us to dynamically change the properties of CPG circuit according to the current situation in real-time. To this aim, the concept of neuromodulation mechanism is introduced to modulate a CPG circuit. To verify the feasibility of this approach, this concept is applied to the control of a 3-D biped robot which is intrinsically unstable. In order to explore the parameters of the CPG circuit with a neuromodulation mechanism, an evolutionary algorithm is employed in this study. Simulation results show that the neuromodulation mechanism dynamically changes synaptic weights of the CPG circuit. This synaptic change leads to creating different behaviors, such as walking behavior and stepping behavior, from the same circuit.

Providing three-dimensional information to operators is a vital technology to operate robotic systems remotely. ITER, which is the world's largest fusion energy experiment, requires maintenance by robotics devices operated remotely because of its radiation environment. Applicable sensors are highly restricted due to the radiation. Authors propose a method using one moving camera and multi-view stereo technology to obtain point clouds as three-dimensional information for operators. As multi-view stereo technologies, Structure-from-Motion and Patch-Based Multi-view Stereo are adopted. Authors tested the proposed method and confirmed the method is capable to create point clouds successfully.

Many serious injuries occur in preschools. Effective injury prevention requires measures customized to the individual preschool. This paper proposed a field-adaptive injury prevention support system that combines both epidemiological analysis of big data of accidents occurred at Japanese preschools and video analysis on accidents/incidents occurred at a specific preschool. While the big data analysis revealed serious injury patterns common in preschools, the video analysis allowed us to extract behavioral patterns in real situations arising at the target preschool. Analysis from both sides enabled the grasping of the behaviors and environments that could lead to serious accidents at the target preschool.

Robotics intersects with children in diverse ways; it opens new scientific research fields of understanding humans with collaborating with psychologies and other related fields. At the same time, it is expected to offer useful applications for early childhood education and therapy. But, it has to be recognized that the robotics technology could be a double-edged sword, meaning that it could be hazardous if we did not exploit it in appropriate ways. Robots are thought to have double character; sometimes they show human-like features but other times they just look like an object. We need to understand the character well and consider appropriate forms of application based on the character. In this paper, firstly we will review the past studies around robotics and children, and we will also discuss the potential risk of robotics for children. Then, we will propose some new ideas for the application of robotics for early childhood education and therapy, considering the double character of robots.

<p>The impacts of robots and ICT in care settings have not been sufficiently evaluated, particularly in relation to workers' workload. The purpose of this paper is to evaluate quantitatively the effects of introducing communicative robots on night shift duties of nursing facility workers. The subjects are five late-night care workers, looking after elderly people to whom communicative robots with an infra-red radiation monitoring system was introduced. We investigated fatigue level using the 'method for checking subjective symptoms". Assessments were conducted at the beginning of the night shift (16:30), before dinner (20:00), before nap (00:00), after nap (02:00) and at the end of the night shift (09:50) before and 4 weeks after introduction. The effects of the system on the nighttime work burden and frequency of accidents were compared. During the fourth week, compared with the pre-introduction phase, the total fatigue level was improved before nap (p < 0.05), after nap (p < 0.05), and the end of the night shift (p < 0.001). Along with this improvement, the accidents especially the trauma accidents decreased. The introduction of a communicative robot with a monitoring system significantly improved the total fatigue level of late night nursing care workers and alleviated the nighttime work workload. </p>
