This paper describes the development of a novel humanoid robot foot/ankle based on an orientation Parallel Kinematic Mechanism for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotation motions. In order to enable the humanoid robot safely t...

We aim to develop a humanoid robot which can go anywhere an ordinary human covers. For such purpose, we consider enhancing the walk and work capabilities of a humanoid robot by integrating manipulation and locomotion. Especially, we focus on three motions of a humanoid robot: pushing a heavy object placed on the floor, working while thrusting a hand on to a desk, and ascending large steps while...

Developing a robust, flexible, closed-loop walking algorithm for a humanoid robot is a challenging task due to the complex dynamics of the general biped walk. Common analytical approaches to biped walk use simplified models of the physical reality. Such approaches are partially successful as they lead to failures of the robot walk in terms of unavoidable falls. Instead of further refining the a...

In this paper we present a humanoid robot, HRP-2P, which can walk, lie down and get up. We believe that HRP-2P (154 cm height and 58 kg weight) is the first humanoid robot that is the size of a human and can lie down and get up. Biped walking is realized by a walking pattern generator using a preview control and a feedback control. The lying down and getting up motions were made possible by HRP...

This thesis describes the design and implementation of a Walking Algorithm for the humanoid robot. The humanoid is intended to be an autonomous robot, and has a total of 6 degrees of freedom coming from the hip joint, knee joint and ankle joint for each leg. The aim of this thesis project is to develop a walking pattern to control and walk in a stable manner. Exploit methods for developing a na...

This paper describes our research efforts aimed a t understanding human being walking functions. Using motion capture system, force plates and distributed force sensors, both human being and humanoid H7 walk motion were captured. Experimental results are shown. Comparison in between human being with H7 walk in following points are discussed : 1) ZMP trajectories, 2) torso movement, 3) free leg ...

Biped locomotion for humanoid robots is a challenging problem that has come into prominence in recent years. As the degrees of freedom of a humanoid robot approaches to that of humans, the need for a better, robust, flexible and simpler maneuverability becomes inevitable for real or realistic environments. This paper presents a new method of controlling the trajectory of a humanoid robot on the...

This paper describes the development of a novel humanoid robot ankle based on an orientation Parallel Kinematic Mechanism (PKM) for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotational motions. In order to enable the humanoid robot safel...

This paper proposes a central pattern generators based control architecture using a frequency adaptive oscillator for learning to locomotion of humanoid robot. Central pattern generators are biological neural networks that can produce coordinated multidimensional rhythmic signals, under the control of simple input signals. They are found both in vertebrate and invertebrate animals for the contr...

This paper is mainly to concern the research of auto-balance control for the humanoid robot. A stable gait planning is the most essential and important part in the study of humanoid robot. Therefore, we design and implement a fuzzy auto-balance controller. Firstly, this paper introduces the humanoid robot (NCKU-1) that we construct and addresses the overview of our robot system, which includes ...
