Design methodology, synthesis, and control strategy of the high-speed planetary rover

Frontiers of Mechanical Engineering 2024, Volume 19, Issue 2, doi: 10.1007/s11465-024-0783-5

Abstract: The planned missions to explore the surfaces of the Moon and Mars require high exploration efficiency, thus imposing new demands on the mobility system of planetary rovers. In this paper, a design method for a high-speed planetary rover (HPR) is proposed, and the representative configurations are modeled and simulated. First, the influence of the planetary surface environment on the design of HPRs is analyzed, and the design factors for HPRs are determined by studying a single-wheel suspension. Second, a design methodology for HPRs is proposed. The adaptive suspension mechanisms of a four-wheeled rover are synthesized using the all-wheel-attachment condition and position and orientation characteristics theory, which are expressed in the form of a graph theory for the increase in elastic components and active joints. Finally, a dynamic model is built, and a simulation is carried out for the proposed rover. The validity of the proposed method and rover is verified, thus highlighting their potential application in future planetary exploration.

Pathogen evolution, prevention/control strategy and clinical features of COVID-19: experiences from China

Frontiers of Medicine 2023, Volume 17, Issue 6,   Pages 1030-1046 doi: 10.1007/s11684-023-1043-5

Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported at the end of 2019 as a worldwide health concern causing a pandemic of unusual viral pneumonia and many other organ damages, which was defined by the World Health Organization as coronavirus disease 2019 (COVID-19). The pandemic is considered a significant threat to global public health till now. In this review, we have summarized the lessons learnt during the emergence and spread of SARS-CoV-2, including its prototype and variants. The overall clinical features of variants of concern (VOC), heterogeneity in the clinical manifestations, radiology and pathology of COVID-19 patients are also discussed, along with advances in therapeutic agents.
