A control method is proposed for a tensegrity robot to generate legged-rolling locomotion (i.e., rolling movement produced by a legged system). The robot has a minimal structure composed only of two rods and four elastic cables. The difficulty of the control arises from the minimalistic structure th…
Quadrupedal locomotion involves coordinated interaction between limbs and torso, enabling them to achieve remarkable movement performance and adapt effectively to various environments. In previous studies, mathematical dynamic models of quadrupeds have been established to investigate the mechanisms
Quadrupeds exhibit remarkable locomotion performance through the coordination between their limbs and torso. From past biological knowledge, it is understood that during walking, the forelimbs primarily contribute to braking, while the hindlimb are responsible for propulsion. However, in the field o

In the natural world, benefited from the advantages of the spine, quadrupeds exhibiting extraordinary flexibility which allowing them to move efficiently on variable terrains. The previous researches have indicated the legged robots which efficiently utilizing their spine can achieve rapid and stabl…
The quadrupeds have wider active territory than humans. Their bodies can adapt various environments through evolution, enabling the efficient, elegant gait for their legged locomotion. Previous researches have indicated lots of examples of utilizing the advantages of body to achieve environment adap…
The movement of the legs involves the interaction between the feet and the ground. Consequently, most animals possess a wide variety of foot morphologies and multifunctional capabilities. The selection and switching of these foot functions are passive and environment-dependent, ensuring environmenta…
This paper introduces a novel X-shaped walker with telescopic legs and investigates its control method with the aim of generating a stable wheel gait on a horizontal plane without including zero dynamics which is essentially unstable and difficult to stabilize. First, we outline a planar 6-DOF robot…
Rescue robots require versatility and the capability to operate in various environments to carry out a diverse set of tasks effectively. The eccentric paddle (ePaddle) mechanism stands out for its high efficiency and adaptability. Generally, it is designed as a quadruped robot with a combined struct…
This paper presents a water walking robot with 6 feet which consists of a rimless wheel and a flywheel, and has a foot attached to the tip of each leg. First, in order to make the robot walk on water, we propose a foot control method by imitating the legs of some animals that can walk on water. Seco…
This paper proposes novel passive-dynamic walk-ers formed by two cross-shaped frames and eight viscoelastic elements. Since it is a combination of two four-legged rimless wheels via viscoelastic elements, we call it viscoelastically-combined rimless wheel (VCRW). Two types of VCRWs consisting of dif…
This paper introduces a planar tensegrity robot that walks passively and cyclically on a gentle downhill, where its gait versatility can be strengthened by applying actuation forces on the connection cables. The novelty of this work is that we design the structure of this passive robot inspired by t…
This paper proposes a novel method for generating an underactuated bipedal gait that completes in one step. First, we introduce an underactuated biped robot model that has a circular torso as a reaction wheel. Second, we consider an input-output linearization to formulate an output-following control…
