While most modern-day quadruped robots crouch their limbs during the stance phase to stabilize the trunk, mammals exploit the inverted-pendulum motions of their limbs and realize both efficient and stable walking. Although the flexibility of the shoulder region of mammals is expected to contribute t…
The bodies of quadrupeds have very complex muscle-tendon structure. In particular, it is known that in the horse hindlimb, multiple joints in the leg are remarkably interlocked due to the muscle-tendon structure. Although the function of these interlocking mechanisms during standing has been investi…
An optional robotic arm unit, like animals' neck, allows quadruped robot to achieve multifunctional tasks such as manipulation and patrol. However, increases in body weight due to the neck unit will make energetic issues in legged robots' locomotion more serious. This study presents a minimal decent…
