Bio‐Inspired Soft‐Rigid Hybrid Smart Artificial Muscle
In article number 2206342, Hongmiao Tian and co‐workers propose a soft‐rigid hybrid smart artificial muscle (SRH‐SAM), which ingeniously coordinates the actuation, load‐bearing, and sensory systems. Based on the SRH‐SAM, an advanced approach for a reconfigurable blazed grating plane and a new strategy for controllable attachment/detachment transformation...
Artificial muscles are of significant value in robotic applications. Rigid artificial muscles possess a strong load‐bearing capacity, while their deformation is small; soft artificial muscles can be shifted to a large degree; however, their load‐bearing capacity is weak. Furthermore, artificial muscles are generally controlled in an open loop due to a lack of deformation‐related feedback. Human arms...
With the basic objective of giving a feasible path in online path planning problem for unmanned air vehicles, smoothness requirement should be considered for further to satisfy more special applications. The paper emphasizes this realistic requirement, and presents an integrated solution based on a leader-follower decision idea. In the solution, global and local optimization strategies are analyzed,...
In this paper, a real-time path planning approach in consideration of threats information sharing is proposed for multiple unmanned aerial vehicles (UAVs) with predetermined rendezvous in hostile environment. This approach obtains turn angles in two-dimensional (2-D) rough terrain by fuzzy reasoning with feedback on rule base. Virtual subgoal is defined and applied to make full use of the threats...
With the rapid development of intelligent building, the requirement of automatic recognition of digital meter reading is increasingly urgent. Based on image processing, this article uses iterative global threshold to binarize the images and then adopts projection method to locate the target regions and divide the numbers. Features are extracted and back-propagation neural network is used to read the...
Based on image recognition and wireless shortrange transmission, we designed and implemented a kind of equipment to identify the value of several digital domestic instruments such as kilowatt-hour meter and gas meter. CMOS image sensor is used to form focused image of the meter reading. Then, the digital image is processed by a high-performance DSP processor with advanced neural network algorithm...
