In order for multiple robots to accomplish a required task together, they need to communicate, organize themselves and cooperate. We have discussed these issues for the distribute autonomous robot system. The developed technologies are applied to the football game, in which the multiple mobile robots will maneuver and handle the ball towards the goal. The robots we use are holonomic, omni-directional...
In our current research, we are developing a holonomic mobile system which is capable of running over the step. This system realizes omni-directional motion on flat floor using special wheels and passes over non-flat ground in forward or backward direction using the passive suspension mechanism. In order to realize the high mobile performance during step climbing, it is required to reduce wheel slippage...
The objective of our research is to develop a wireless sensor network construction system by teleoperated mobile robot. Our proposed system is that mobile robot carries the sensor nodes and deploys them for constructing wireless network in the working environment. For deployment of the sensor nodes, we introduced to estimate maintainable data transfer speed based on statistic approach. When estimated...
In our current research, we are developing a holonomic mobile system which is capable of running over the step. This system realizes omni-directional motion on flat floor using special wheels and passes over non-flat ground in forward or backward direction using the passive suspension mechanism. Odometry is popular position tracking scheme for a wheeled mobile robot, however, in the case of non-flat...
After the earthquake, it is very important to recognize the situation of the disaster area as soon as possible. Therefore, the objective of our research is to realize information gathering system applying wireless sensor network technology. This paper describes about development of a novel camera node for gathering the information and also experimental results by using the camera node via wireless...
In case of disasters such as a big earthquake in the urban city, it is one of the most important problems to acquire information of the disaster environment, victimspsila position and status. Although, at present, rescue corps and dogs strive to find the victims everywhere in the disaster area, it takes too long time. To address this problem, a small sized wireless ubiquitous sensor node called ldquoRescue...

In our current research, we are developing a force assistance system for standing up motion. Our developing system realizes the standing up motion using the support bar with two degrees of freedom and the bed system which can move up and down. In this paper, we develop the force assistance system which realizes the natural standing up motion using remaining strength of the patient. Our key ideas are...
We are conducting research and development in technology for unifying the information of a large number of intelligent sensors distributed in a disaster-stricken area. Operating effectively as a system in real time, network household electric appliances, a personal digital assistant (PDA), a robot, etc. provided information and an action plan for a stricken area's situation. In this paper we introduce...

In our current research, we are developing a power assistance system for standing up motion. Our developing system realizes the standing up motion using the support bar with two degrees of freedom and the bed system which can move up and down. In this paper, we develop the control scheme which realizes the natural standing up motion with fewer loads to the patient. For developing control scheme, we...
