We present the design, fabrication, and characterization of single antagonistic SMA microactuators allowing for uni- bi-directional self-folding origami-inspired devices, respectively. Test devices consist two triangular tiles that are interconnected by double-beam-shaped fabricated from thin foils 20 µm thickness with memory shapes set to a 180° folding angle. Bi-directional is achieved combin...

Multi-scale representation plays a critical role in the field of edge detection. However, most existing research focuses on one two aspects: fast training and accurate testing. In this paper, we propose novel multi-scale method to resolve balance between them. Specifically, according multi-stream structures image pyramid principle, construct down-sampling network lightweight up-sampling enrich ...

This article has focused on evaluation and identification of effective parameters in positioning performance with an odometry approach of an omni-directional mobile robot. Although there has been research in this field, but in this paper, a new approach has been proposed for mobile robot in positioning performance. With respect to experimental investigations of different parameters in omni-dire...
