Rapid advances in robot technology have been made in recent years. In connection with these advances, robots are expected to be utilized in a variety of places and environments. This study describes, (1) a method which allows a robot to measure the location of its destination in the real world based on an image obtained from a single camera, and (2) a method of navigating a robot to a destination...
The robot technology is rapidly developing in recent years. In connection with this technology, a robot activity is expected in various places or various environments. Therefore, this study describes 1) how the location of the destination of the robot in real world is measured based on the image obtained by one camera and 2) how the robot is navigated to the destination where a user points out on...
We have proposed the concept of Man-Machine Synergy Effectors. These are high-performance tools for human use, which are realized by introducing robot technology. It becomes possible to perform conventionally impossible tasks by human alone or robot alone, because the system synergizes better assets of both parties. In this paper, the concept of Man- Machine Synergy Effector is described. Then, the...
Dead reckoning and star reckoning are two basic self-localization methods for vehicles, but each method has inherent weakness. To recover these weaknesses, sensor-fusion via an initial state observer has proposed. However, the method can be applied under the assumption that the vehicles move in the limited field. In this paper, we propose a new sensor- fusion method by using a grid point observer...
In this paper, we introduce a sensor fusion method for position locations of mobile robots using an initial state observer and propose a gain calculation method. We confirm the effectiveness of the proposed method by experiments. Experimental results illustrate the initial state observer based sensor fusion method with proposed gain calculation method has almost the same performance as EKF. Moreover,...
This paper focuses on the problem of global stabilization of a two-wheeled mobile robot. We propose a global exponentially stabilizing controller for a two-wheel mobile robot based on the discontinuous finite-time homogeneous controller for chained systems. Moreover, we demonstrate the effectiveness of proposed method through an experiment using a "Khepera 2" mobile robot
