Performance analysis of Global Navigation Satellite Systems (GNSS) collaborative positioning accuracy is a challenging task since there are too many impact factors. To simplify the analysis, the collaborative dilution of precision (CDOP) model is proposed to specify the multiplicative effect of various factors on the accuracy of collaborative positioning. Based on this CDOP model, the theoretical...
In this paper, we propose a new re-coloring algorithm to enhance the accessibility for the color vision deficient (or colorblind). Compared to people with normal color vision, people with color vision deficiency (CVD) have difficulty in distinguishing between certain combinations of colors. This may hinder visual communication owing to the increasing use of colors in recent years. To address this...
In the study, we report a microfluidic-based dispenser fabricated by standard soft lithography of PDMS (polydimethylsiloxane) for sub-microliter range precise pipetting. The key feature of the microfluidic-based dispenser is the incorporation of a pressure-generating unit providing the driving force for precise and quick aqueous liquid sampling and pipetting. The microfluidic-based dispenser features...
Autonomous mobile robots are required to know precisely their position and orientation in order to successfully perform their mission. Since multi-robots collaboration has outstanding advantages, multi-robot collaborative localization method has been studied widely in recent years, but robots should have high performance in this method. As wireless sensors became smaller and cheaper in the recent...
An algorithm based on immune network model for an unknown environment is proposed to accomplish multi-robotspsila exploration task fast for an unknown environment. Each local environment condition sensed by the robots is considered as antigen while robot is regarded as antibody respectively. Each robot works independently according to the antigen information. The coordination of the robots can be...
