Animals can instantly exhibit versatile behaviors in response to their circumstances to
survive in harsh natural environments. For example, many animals chase prey, escape from …

Designers of legged robots are challenged with creating mechanisms that allow energy-
efficient locomotion with robust and minimalistic control. Sources of high energy costs in …

Efficient locomotion in terrestrial vertebrates relies on intra-limb coordination that emerges
through interaction with the environment and passive interlocking of the musculoskeletal …

Intending to further simplify motion planning and control of quadrupedal locomotion through
emergence, we propose a legged locomotion controller inspired by the sensorimotor …

Dynamic human movements are achieved by appropriate constraints on the degrees of
freedom of the complex and flexible human body. The anatomy trains (ATs) theory explains …

In this study, the cam-like passive mechanism, known as the engage–disengage
mechanism (EDM) of the intertarsal joint of ratites, and its design principles are investigated …

Fascinated by these adaptive animal behaviors, many researchers have attempted to
understand the source of animal intelligence, and concepts of embodiment and …

This report addressed the stance mechanism in a non-avian dinosaur Protoceratops
andrewsi hindlimbs using a robotic approach. Our previous studies demonstrate the passive …

Horses, which exhibits high locomotor efficiency among mammals [1], have historically
played a vital role in supporting pre-industrial society due to their superior power, speed …

刺激応答機構を用いた自動機械の歴史は紀元前の自動ドアにまでさかのぼる [1].
電子機器の発達していない時代にはカムやギア, スイッチやバルブを組み合わせた複雑な産業機械 …
