We have been developing a new vehicle, “Tread-Walk 2”, which supports walking for elderly. A control algorithm to improve the operability has been constructed. As the first step, we accurately estimated the user's anteroposterior force from the motor current value without the force sensor. This method is to develop a new mechanical model that considers the friction forces of the treadmill and remove...
We have been developing a portable system that low vision people can verify life environment without other people's supports. We call this system view-aid. Viewaid takes a picture with small, wireless CMOS camera when low-vision people want to verify life environment. Images taken with this camera are transmitted to the PDA with the analogue signal of 1.2 GHz band. It is received by the receiver,...
We have developed a gait rehabilitation robot for hemiplegic patients using the treadmill. A walk phase, which includes time balance of stance and swing legs, is one of the most basic indexes to evaluate patients' gait. In addition, the walking phase is one of the indexes to control our robotic rehabilitation system. However, conventional methods to measure the walk phase require another system such...
In these days, elderly population is increasing in Japan. Demands on rehabilitation works might be larger as the old increase. In the authors' laboratory, the virtual walk system has been designed and implemented. The system is intended to aid rehabilitation works with the virtual reality technology. Using commercially-supplied products, the proposed system is easy to be introduced to home with low...
