摘要：In-situ exploration of asteroid surfaces is of great scientific *** actuated rovers have been released to asteroid surfaces but without enough *** investigate the attitude control characteristics of the cubic rover for asteroid surface exploration,a series of experiments are carried out using the self-designed rover and the low-gravity *** experiments focus on two major themes:The minimum flywheel speed for cubic rover to produce a walking motion in different conditions,and the relationship between the rover’s rotation angle and the flywheel speed in twisting *** rover’s dynamical descriptions of the walking and twisting motions are first *** features and design of the low-gravity testbed are then summarized,including its dynamics,setup,and validation.A detailed comparison between the dynamic model and the experimental results is presented,which provides a basic reference of the cubic rover’s attitude control in low-gravity environments.

摘要：Biomanufacturing(BM)is a multidisciplinary area incorporating the characteristics of living organisms and engineering principles to create valuable products for various sectors,including medicine,energy,and the *** has undergone a remarkable transformation in the last two decades,entering the era of BM4.0 and becoming a pivotal driver of the sustainable ***,Japan has made significant advances in BM,contributing to its development through the creation of innovative materials,advanced processes,and interdisciplinary ***,because of certain development policies,this research has not been widely recognized on an international *** paper provides a comprehensive summary of the research progress made by renowned Japanese laboratories and researchers in biomedical materials,bio-three-dimensional(3D)printing,and biomedical applications in the last five *** unique contributions are introduced and analyzed,illuminating the distinctive approaches and breakthroughs within each ***,this review highlights the current challenges and prospects of *** viewpoints presented in this paper are intended to serve as a valuable reference for scholars studying BM in Japan.
