It is easier for bipedal robots to exist in a human oriented environment than for other types of robots. Furthermore, dynamic walking is more efficient than static walking. For a biped robot achieve dynamic balance while walking, a dynamic gait must be developed. Two different approaches to gait generation are presented—an intuitive approach using software for gait animation, and a periodic app...

This study focuses on the passive dynamic walking to enable a biped robot on level ground to walk efficiently with simple mechanisms. To build an efficient bipedal robot, utilizing the dynamical property of the robot system is a useful approach. McGeer studied passivedynamic walking, and showed a biped robot without actuators and controllers can walk stably down a shallow slope in simulations a...

The bipedal structure is one of the most versatile ones for the employment of walking robots. The biped robot has almost the same mechanisms as a human and is suitable for moving in an environment which contains stairs, obstacle etc, where a human lives. However, the dynamics involved are highly nonlinear, complex and unstable. So it is difficult to generate human-like walking motion. To realiz...

This paper presents the biped Lucy and the first experimental results of this robot. Lucy is actuated by Pleated Pneumatic Artificial Muscles, which have a very high power to weight ratio and an inherent adaptable compliance. These characteristics will be used to make Lucy walk in a dynamic stable way while exploiting the adaptable passive behaviour of these muscles. The paper will describe bri...

In the biped robotics domain, head oscillations may be extremely harmful, especially if robot is teleoperated, since vibrations strongly reduce operator’s spatial awareness. particular, undesired occur in under-actuated robots, where springs and passive mechanisms are used to achieve a human-like motion. This paper proposes an approach of robot’s head; proposed solution does not affect dynamic ...

We propose a model-based reinforcement learning algorithm for biped walking in which the robot learns to appropriately modulate an observed walking pattern. Viapoints are detected from the observed walking trajectories using the minimum jerk criterion. The learning algorithm modulates the via-points as control actions to improve walking trajectories. This decision is based on a learned model of...

This paper investigates the optimization and control of biped walking motion on a rolling cylinder. We design a balance controller for a simplified linear model of a biped robot, which comprises a foot connected to a lump mass through an ankle joint and a translational spring and damper. We also derive a collision model for the system consisting of the cylinder, supporting leg, and swing leg. W...
