A new 3D biped prototype with small DOF, SKIPPER, was developed. As an important component of a running controller for this robot, an aerial posture controller is presented. This is the extended version of planar running controller, which was previously developed for a passive one-legged hopping robot, and plays important roll for orbital stabilization at the lowest control layer. The controlle...

Recognizing its surroundings is important for biped robots seeking a destination. In this paper, we propose a motion planning method of a biped robot including path planning and obstacle avoidance. The robot obtains distance information on its surrounding environment from images captured by a stereo camera system, and generates a 3D map, then, builds a 2D grid map that locates flat floor region...

Biped robot control techniques are usually based on the tracking of pre-computed reference trajectories. Therefore, to achieve autonomy in locomotion, it is necessary to store a set of trajectories handling all the possible situations and events the system is susceptible to encounter. This paper presents a method for the generation of walking gaits for biped robots. Theses gaits define locomoti...

In this increasingly aging society, the needs for robots to assist human activities in daily environments such as offices, homes, and hospitals are growing rapidly. In such environments originally designed for human beings, biped robots, which have almost the same mechanisms as a human, present many advantages than wheeled robots like obstacle avoidance capabilities for its possibility of disco...

In this paper, the method of generating biped robot motion using recorded human gait is presented. The recorded data were modified taking into account the velocity available for robot drives. Data includes only selected joint angles, therefore the missing values were obtained considering the dynamic postural stability of the robot, which means obtaining an adequate motion trajectory of the so-c...

Controlling a biped robot with a high degree of freedom to achieve stable movement patterns is still an open and complex problem. Thus, the development of control mechanisms for biped walking have become an important field of research. With growing calculation power of computer hardware, high resolution realtime simulation of such robot models in effect becomes all the more applicable. This the...

As a biped robot has become more anthropomorphic and performs a various task on behalf of human, the research on biped robots gradually attracts much attention and is progressing dynamically. However, biped robots are difficult to control due to their nonlinear and coupled dynamics. First, Inverted pendulum [1] is applied to interpret some characteristics of human walking. Later, researchers co...

The purpose of this research is to generate a stable motion for a hydraulic actuated biped robot. Since the application effect of most dynamic biped robot locomotion theories is not very well and the static walk pattern is hard to realize on human-sized hydraulic actuated biped robot because of the small size of foot compared with body height. In this study, we propose a trajectory planning met...

This paper proposes a method of adaptively generating a gait pattern of biped robot. The gait synthesis is based on human’s gait pattern analysis. The proposed method can easily be applied to generate the natural and stable gait pattern of any biped robot. To analyze the human’s gait pattern, sequential images of the human’s gait on the sagittal plane are acquired from which the gait control va...

Humanoid robots are used as a research tool to understand bipedal locomotion. When pushed, a humanoid robot must be able to avoid falling and return to a balanced configuration. This is called push recovery and can be achieved using proper foot placement. Depending on the freedom of movement, one or multiple steps are taken to accomplish this goal. It is expected that foot placement can also be...
