Rapid interest in identifying specific biomarkers has been sparked by the development of wearable electrochemical sensors for physiological and biological monitoring via noninvasive measurement. During anaerobic metabolic circumstances, lactate content become critical diagnostic hypoxia. To improve sensitivity sweat biosensors detecting concentrations, this study, metal–organic framework (MOF)-derived NiCo-based layered double hydroxides (m-NiCo LDHs) with N-doped graphene quantum dots...

Humanoid robots dynamically navigate an environment by interacting with it via contact wrenches exerted at intermittent poses. Therefore, is important to consider dynamics when planning a sequence. Traditional approaches assume quasi-static balance criterion reduce the computational challenges of selecting sequence over rough terrain. This however limits applicability approach dynamic motions are required, such as walking down steep slope or crossing wide gap. Recent methods overcome this...

This paper proposes ElevatorTalk, an elevator development and management system based on the Internet of Things (IoT) approach called IoTtalk. modularizes software into components so that we can develop flexible scalable car scheduling algorithms. ElevatorTalk consists three subsystems: cars, scheduler, operating (ECO) panel. The first two subsystems are used to systems, third subsystem is receive requests issued by passengers. These work in parallel, communicate with each other through...

Object search is a fundamental ability for service robot to provide higher level services. We focus on object in an environment with limited free space place objects and constrained viewpoints observe the environment, such as shelf or cupboard. propose planner based A* algorithm tree node sampling. The proposed approach also combines visual arm manipulation search. In other words, searches occluded target by either repositioning one of accessible its moving platform view from different pose....

Humanoid robots maintain balance and navigate by controlling the contact wrenches applied to environment. While it is possible plan dynamically-feasible motion that applies appropriate using existing methods, a humanoid may also be affected external disturbances. Existing systems typically rely on controllers reactively recover from However, such fail when robot cannot reach contacts capable of rejecting given disturbance. In this letter, we propose search-based footstep planner which aims...

We propose a humanoid robot navigation planning framework that reuses previous experience to decrease time. The is intended for navigating complex unstructured environments using both palm and foot contacts. In environment, discrete-search-based contact space planners trade-off between high branching factor action flexibility. Although approaches such as weighted A*, ARA* ANA* could speed up the search by compromising on optimality, they can be very slow when heuristic inaccurate. proposed...

A new automatic weighted image fusion algorithm is proposed. The current averaging has good rapidity, but its quality depends on the choice of weight values to a great extent. In order choose more reasonably, K-L transform adopted, which advantages in multi-component information reduction. available source images concentrated independent principal component matrixes. redundant from different decreased and coefficients are thereby determined. Comparison experiment performed with infrared...

Humanoids' abilities to navigate stairs and uneven terrain make them well-suited for disaster response efforts. However, humanoid navigation in such environments is currently limited by the capabilities of planners. Such planners typically consider only footstep locations, but planning with palm contacts may be necessary cross a gap, avoid an obstacle, or maintain balance. considering greatly increases branching factor search, leading impractical times large environments. In previous work we...

It is a remaining challenge for intelligent robot to interact with human daily living environment; one of the scenario grasping objects from table. Because massive variety in life, it still hard task robots achieve. In this work, we propose an RGB-D eye-in-hand system and effective grasp selection algorithm without prior knowledge object parallel-plate gripper, depending on depth information direction. Without modeling, learning, training segmentation, can find optimal position place gripper...

This paper presents our new intelligent interactive robot, which is constructed to eagerly provide multi-functional services in an office environment. In order endow a full capability of robots for realizing so-called human-robot interaction (HRI) , we propose sensor fusion based human detection and tracking system pose estimation deal with number situations may take place the Not only by these perceptions, interact robot also some natural way, such as touching interface screen talking...

In this paper we explore discrete search-based contact space planning for humanoids using both palm and foot in complex unstructured environments. With a high branching factor sparse contactable regions, it is challenging the planner to find sequence such environments quickly. Therefore, propose learn function which predicts traversability - measure of how quickly can generate sequences traverse certain region. By including learned estimate into heuristic planner, bias search areas with more...

A humanoid robot navigating in an unstructured environment requires knowledge of the affordances which allow it to make contact with environment. This often comes from a perception system, processes data 3D sensors such as LIDAR and extracts available areas for contact. Because systems run independently robot's planner, without goal, they must process entire visible area. In large environments, or those complex geometry, system may spend significant time processing that planner will never...

Dissolved oxygen (DO) is a key parameter in assessing water quality, particularly aquatic ecosystems. The reduction reaction (ORR) has notable prevalence energy conversion and biological processes, including biosensing. Nevertheless, the long-term usage of submersible DO sensors leads to undesirable biofilm formation on electrode surface, deteriorating their sensitivity stability. Recently, reactive species (ROS), such as two-electron pathway ORR byproduct, H2O2, had been known for its...
