In this study we focus on bio-inspired legged locomotion concepts. A primary goal of comparative biomechanics is to understand the fundamental physics of locomotion within an evolutionary context. Such an understanding of legged locmotion results in a transition from copying nature to borrowing strategies for interacting with the physical world in design and control of bio-inspired legged robot...

The modeling of legged locomotion is of central importance to the successful animation of human and animal gures. Since legged locomotion is typically diicult to animate using only kinematic modeling, alternative, more physically-based methods have to be employed. This paper discusses several methods for dynamic simulation of legged locomotion. Typical components of a dynamic simulation system ...

For legged locomotion, animals and humans rely more on decentralized feedback control than on the central control approach common in humanoid robotics. We present evidence that the decentralization does not hamper fidelity and may present an alternative approach to robust locomotion of legged robots from prosthesis to humanoids. Keywords-locomotion, decentralized control, bioinspiration

A primary goal of comparative biomechanics is to understand the fundamental physics of locomotion within an evolutionary context. Such an understanding of legged locomotion results in a transition from copying nature to borrowing strategies for interacting with the physical world regarding design and control of bio-inspired legged robots or robotic assistive devices. Inspired from nature, legge...

Elastically-suspended loads can reduce the energetic cost of legged robot locomotion over flat ground. In this paper, we studied the effect of elastically-suspended loads on the mobility of legged robot locomotion over rough terrain. The power input and speed of a simple hexapod robot running over rough terrain with an elastically-suspended load and a rigidly-attached load was compared. On aver...

Legged robots display a characteristically periodic motion. Measuring and tracking this motion has traditionally been performed using general inertial measurement techniques. While widely applied in robotics, this approach is limited in dynamic legged locomotion due to the excessive accumulation of drift from severe impact shocks (nearly 9g in single leg experiments). This paper introduces the ...

In order to develop a high performance working robot, we designed and developed a new robot based on the concept of "Limb Mechanism" for integration of legged locomotion and arm manipulation. The developed robot has six limbs which can be used for both locomotion and manipulation. Six limbs are set on vertices of regular hexagonal body so that this robot can have ominidirectional manipulability...

Legged locomotion is used by most of the animals and human beings on the earth. Legged locomotion is preferred over the wheeled locomotion as it can be used for both flat and rough terrains. In this paper, an attempt has been made for the dynamic modelling and simulation of four legged jumping robots with compliant legs. Sagittal plane and bounding gait has been used. For energy saving passive ...

Despite the impressive demonstrations of energy efficient legged robots in the past, there are still a number of challenges remained to compete with legged locomotion of biological systems. In order to optimize energy efficiency of a legged robot, we typically need to sacrifice versatility: our robots have usually limited locomotion speed, lack of behavioral diversity, complex mechanical design...
