Fully 3D‐Printed Wave‐Wound Electromagnetic Motors
Advanced Materials Technologies, EarlyView.This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Hydrodynamic Analysis of Thrust Bearing for Scroll Compressor
, 2007 渦卷式壓縮機是在80年代才商品化的產品。但因具優異的效率，加上振動小、噪音低，因此有逐漸取代其他類型壓縮機在小噸數壓縮機市場的趨勢。 此種壓縮機在運轉過程中常會遇到止推面過度磨耗的問題，造成壓縮機耗功突然昇高，除了影響效率，最終也將使壓縮機損壞。對損壞止推面的觀察時，發現在止推軸承的表面有許多磨痕。此現象乃由於壓縮機在運轉時之高負載，造成止推軸承和動渦卷的乾摩擦所造成的。 本研究針對中凸的止推軸承設計進行分析。止推軸承利用中凸形狀特性的所形成的楔形油膜 ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
