This paper presents biped walking control using a library of optimal trajectories. The biped walking control problem is formulated as an optimal control problem. We take advantage of a parametric trajectory optimization method to find the periodic steady-state trajectory in regular walking. Then we use Differential Dynamic Programming (DDP) to generate a library of optimal trajectories and loca...

This paper introduces a novel stereo vision based simulation system for a Humanoid Robot. This stereo vision system and robot controller is simulated dynamically and its performance evaluated for a standard humanoid robot benchmark problem. The vision system presented has been tested by simulating the dynamics of the robot system as well as the image processing subsystem. The real-time image pr...

Development of simple computational schemes to manage zmp to force biped robots into dynamic walking has been an important area. In this paper, a straightforward computational technique to map the body trajectories of a biped, to achieve dynamic walking is suggested. While such works for one mass representation has been reported earlier, here, a three mass representation of a biped robot is con...

Declining birthrate and a growing proportion of elderly people are closed up as social issues in Japan. Especially, a growing proportion of elderly people is seen as an issue in nations of Europe and North America and so on as well as Japan. New labors engaging in the life support and the nursing for the elderly person will need in the future. To supplement the lack of the manpower, the researc...

The planar passive compass-gait biped robot on sloped surfaces is the simplest model of legged walkers. It is a two-degrees-of-freedom impulsive mechanical system known to exhibit, in response to an increase in the slope angle of the walking surface, a sequence of period-doubling bifurcations leading to chaos before falling down at some critical slope without any explanation. The fall is found ...

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...

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...
