Recent advancements in 3D reconstruction, especially through neural rendering approaches like Neural Radiance Fields (NeRF) and Plenoxel, have led to high-quality visualizations. However, these methods are optimized for digital environments employ view-dependent color models (RGB) 2D splatting techniques, which do not translate well physical printing. This paper introduces "Poxel", stands Printable-Voxel, a voxel-based reconstruction framework photopolymer jetting printing, allows...

Abstract In this paper, we present an electrically driven childlike android named ibuki equipped with a wheeled mobility unit that enables it to move in real environment. Since the includes vertical oscillation mechanism, can replicate movements of human center mass and express human-like upper-body even when moving by wheels. Moreover, providing 46 degrees freedom perform various physical expressions. The development , as well implementation testing several functions, is described. Finally,...

Microscale needle technology is important in electrophysiological studies, drug/chemical delivery systems, optogenetic applications, and so on. In this study, dissolvable needle-base scaffold realizes penetration of high-aspect-ratio flexible microneedles (e.g., <5 μm diameter >500 length) into biological tissues. This methodology, which applicable to numerous microneedles, should reduce the invasiveness provide safer tissue penetrations than conventional approaches. As a service our authors...

Predicting the progression of hip osteoarthritis (OA) remains challenging, and no reliable predictive method has been established. This study aimed to develop an artificial intelligence (AI) model predict OA via plain radiographs patient data determine its accuracy.

The fluorescence of NO was obtained by excitation from the 184.9 nm resonance line a low pressure mercury lamp. It found that β (v′=9) emission induced absorption for [NO]=1.0 torr. Quenching bands He or N2 molecules accompanied an enhancement γ bands, v′=4 0 and 1, respectively. When CO added to NO, intensities were weakened. These effects explained following reaction scheme.

Humans can express their emotions with not only facial expressions or gestures but also whole-body motion, even while walking, which are essential for our interpersonal relationships and interaction others. Communication people is considered an important task robots, however emotional by wheeled mobile humanoid robots when moving has been well studied. In this paper, we implemented human-like gait-induced upper body motion in a android ibuki. We hypothesize that the vertical oscillation...

In the present study, fuzzy logic control and genetic algorithms are applied to achieve improved pump operations in a combined sewer pumping station. Pumping rates determined by inference rules corresponding input variables. Genetic used automatically improve through such as selection, crossover mutation. The effects of different fitness functions learning conditions investigated using stormwater runoff model. It is found that current can be adding water quality variables function; reduce...

This paper presents a subjective evaluation of the emotions wheeled mobile humanoid robot expressing during movement by replicating human gait-induced upper body motion. For this purpose, we proposed equipped with vertical oscillation mechanism that generates such motion focusing on center-of-mass trajectory. In experiment, participants watched videos robot's different emotional motions, and assess type emotion shown, their confidence level in answer. We calculated recognition rate average...

Since ancient times, a hug has been one of the most basic ways to express emotions and played an important role in building relationships between people. On other hand, social robots that are designed provide mental health care patients have attracting great attention, hugging humans is becoming more popular. In this study, we propose huggable robot allows intimate interactions robots. Our based on tensegrity structure, which composed rigid elements connected by springs, structure flexibly...

In this study, we propose a novel human-in-the-loop optimization approach for exoskeleton robot control. We develop method to optimize widely-used Electromyography (EMG)-based assistive strategies. If use multiple EMG channels control multi-DoF robots, process becomes complex and requires large amount of data. To make the tractable, exploit synergies both human muscles artificial robots reduce number parameters show that can extract not only from user's muscle activities but pneumatic (PAMs)...

Androids--humanoids with a human-like appearance are studied in limited communities but draw considerable attention. Considering an android integrates numbers of actuators, sensors and devices into system, standardized framework is beneficial to easy-move extension potential applications. In this report, we developed ROS-based software for androids. With the framework, intuitively generating, blending reusing motion aimed be realized. Some applications under they implemented on child-like...

Many researchers have investigated a variety of types robots. In this study, we the centipede type walking robot. The purpose study is realizing transition from straight to bending and reverse by using control width leg stroke only. our experiment, robot walked line curve, following parts on trajectory head unit.

In this study, different glasses were investigated to improve reusable investments. Borosilicate glass (BSG) powder and soda-lime (SLG) prepared by milling broken beakers microscope slides, respectively, used in experimental investments (I-BSG, I-SLG) blending (10wt%) with cristobalite (90wt%). Some properties casting fits evaluated commercial gypsum-bonded investment as the control. Both BSG SLG mainly composed of Si, but had a large Ca content. The transition temperatures approximately...

Scarab beetle larvae do not have appendages to shovel and trunk thick compared body length. Hence, through perplexing. Here, we established observation analysis system of larval found that last instars Trypoxylus dichotomus burrow two different ways, depending on hardness soil. If soft, keep straight line use longitudinal expansion contraction; if hard, they flex rotate body. It...

Expressing emotions through various modalities is a crucial function not only for humans but also robots. The mapping method from facial expressions to the basic widely used in research on robot emotional expressions. This claims that there are specific muscle activation patterns each expression and people can perceive these by reading patterns. However, recent human behavior reveals some expressions, such as emotion “intense”, difficult judge positive or negative just looking at alone....
