The subject of this paper is a hybrid hip biped climbing robot. The hybrid hip provides both prismatic and revolute motion, discretely, to the robot, using a single actuator. This is intended to improve its adaptability in confined environments and its capability to maneuver over and around obstacles. Optimization of the hybrid hip relative to robot size, weight, and actuation limits is conside...

This paper describes a method for composing whole body motions of a humanoid robot. Recently there have been many studies of controlling a humanoid robot, and robots have been acquiring the ability to perform various tasks. However, it is still complicated work for us to create complex whole body motions like humans. In order to solve this problem, we propose a motion composition method that us...

A large number of tasks, from manufacturing to planetary exploration, have been successfully accomplished using single robot systems. Many of these tasks could be completed faster, more reliably, and on a larger scale using a cooperating team of autonomous mobile robots. However, robots must be able to coordinate their actions before cooperation is possible. This work aims to enable robots with...

This paper describes a method to construct a stationary environmental map and estimate the ego-motion of a mobile robot from unknown planar motion by using an omni-directional vision sensor. Most environments where mobile robot works are limited to two-dimensional space and the environmental map which is necessary for mobile robot navigation has also two dimensions. However, conventional “Struc...

As a result of the increase in robots in various fields, the mechanical stability of specific robots has become an important subject of research. This study is concerned with the development of a two-wheeled inverted pendulum robot that can be applied to an intelligent, mobile home robot. This kind of robotic mechanism has an innately clumsy motion for stabilizing the robot’s body posture. To a...
