Targets capture by distributed active swarms via bio-inspired reinforcement learning

Natural swarms arranged from cells to herds are usually decentralized but display intriguing collective intelligence in coordinating individuals across large scales to efficiently achieve their common goals. Learning from nature may provide new strategies for controlling collective dynamics of synthetic swarms to accomplish specific functions. Here, we present a bioinspired computational framework that steers distributed active swarms to collectively capture and merge targets via reinforcement learning. We exploit collective milling structures of natural herds to cage the targets, and adopt a switching control policy inspired by sperms' chiral dynamics to optimize the trajectories of individuals, through which the active swarms can selforganize to enclose single or multiple distant targets in a dynamical, adaptive and scalable manner. There exists a critical swarm size, beyond which the excessive competition between agents would generate large mechanical forces, leading to capture instability but enabling the transition from short-distance to long-distance merging capture of multiple targets. This work provides physical insights into distributed active swarms and could offer a multilevel, decentralized strategy toward controlling swarm robotics in wide applications such as bio-medical devices, machine immunity, and target clearance.

Synthesis and forming behavior of aluminium-based hybrid powder metallurgic composites

引用

International Journal of Minerals,Metallurgy and Materials 2014年第2期21卷 181-189页

作者： M.Ravichandran A.Naveen Sait V.Anandakrishnan department of mechanical engineering Chendhuran College of Engineering and Technology department of Production engineering National Institute of Technology

Aluminium-based metal matrix composites were synthesized from Al-TiO2-Gr powder mixtures using the powder metallurgy technique and their forming characteristics were studied during cold upsetting. Green cylindrical compacts of pure Al, Al-5wt%TiO2, Al-5wt%TiO2-2wt%Gr, and Al-5wt%TiO2-4wt%Gr were made using a 400-kN hydraulic press equipped with suitable punch and die and by sintering at （590 ± 10）°C for 3 h. Cold upset forging tests were carried out, the true axial stress （σz）, the true hoop stress （σ？）, and the true hy-drostatic stress （σm） were evaluated and, their behavior against the true axial strain （εz） was also analyzed. It is observed that the addition of 5wt%TiO2 into the Al matrix increasesσz,σ？, andσm. The addition of both TiO2 and Gr reinforcements reduces the densification and defor-mation characteristics of the sintered preforms during cold upsetting. Microstructure analyses of the as-sintered and cold upset forged speci-mens also were carried out to substantiate the experimental results.
