This paper presents our on-going work in developing service robots that provide assisted-care to the elderly in multi-party settings. In typical Japanese day-care facilities, multiple caregivers and visitors are co-present in the same room and any caregiver may provide assistance to any visitor. In order to effectively work in such settings, a robot should behave in a way that a person who needs assistance...
In this paper, we report on our development of a robotic system that assists people in accomplishing simple tasks in daily life (e.g., retrieving objects for handicapped and elderly people). These tasks, inevitably involve detecting various kinds of objects. In particular, here, we present an interactive method to detect objects using spatial information. Our experimental results confirm the usefulness...
In this paper, we propose a new example of non-holonomic mobile robot, which we call the surface walker. This robot is composed of a hemisphere-shaped shell and a 2-d.o.f. mass-control device (pendulum) inside it, and undergoes the rolling contact constraint between the hemispherical surface of the robot and the ground. Unlike a lot of non-holonomic robots which have ever been researched, the drift...
Recently, several robotic/intelligent wheelchairs have been proposed that employ user-friendly interfaces or autonomous functions. Although it is often desirable for user to operate wheelchairs on their own, they are often accompanied by a caregiver or companion. In designing wheelchairs, it is important to reduce the caregiver load. In this paper we propose a robotic wheelchair that can move with...
In this paper, we propose a remote-interactive mode for a museum guide robot. In this mode, the remote operator can interact with the robot by using voice and gestures through a network. The operator can instruct the robot what to do using nonverbal behaviors such as touching an object on the display screen while saying an instruction. For example, the operator can ask the robot, ldquoBring this brochure...
Needle insertion treatments require accurate placement of the needle tip into the target cancer. However, it is difficult to insert the needle into the cancer because of cancer displacement due to the organ deformation. Then, a path planning using numerical simulation to analyze the deformation of the organ and the timing of puncture is important for the accurate needle insertion. In this study, we...
Several robotic/intelligent wheelchairs have been proposed. Their main research topics are autonomous functions such as moving toward some goal while avoiding obstacles, and user-friendly interfaces. Although it is desirable for wheelchair users to go out alone, caregivers often accompany them. Thus we must consider reducing caregiverspsila load in addition to autonomous functions and user interfaces...
This paper discusses the design of decentralized capturing behavior by multiple mobile robots. The design is based on a gradient descent method with local information. The task of capturing a target is divided into two problems, enclosing behavior and grasping behavior. We give analysis on convergence of the local control policy in enclosing problem. In grasping behavior, we consider the force-closure...
At large-scale urban earthquake disaster, the human search and the information collection are the most important process of rescue activities. This research develops the balloon-cable driven robot for information acquisition from sky at crushed structures at landslide caused by huge earthquake. The balloon, which hangs up several sensors (sensor unit, SU), uses "a natural shape balloon"...
Mutual adaptation process in musical communication is often used for walking support and rehabilitation. But this kind of supporting system is not realized yet. So the purpose of this research is to construct walking support system as a musical communication process. Our strategy is to extend Walk-Mate system, which realizes mutual adaptation process between human and virtual walker by exchanging...
