Abstract :
This system is to support elderly people who need some help in standing up from the bed, walking around, sitting down to the toilet or bed for rehabilitation. In the design of this system, the use of the left function of the user was strongly considered. The experimental mechanism of the walking support system is developed. The basic features are: (1) electrically power-assisted in both motions of standing-up/sitting-down and walking; (2) a sensor system for easier motion instruction for the elderly. Future research includes field test and evaluation of the system functions. The force sensitive motion control method with compensation of gravity on the slope is also discussed
