Abstract
Provided are a system and method for estimating the center of gravity of a walking rehabilitation robot, the system being provided with: a sensor module for estimating the point of the center of gravity, and provided with: a sensor unit mounted on a footplate to sense the pressure when a person walks; output means for outputting a voltage value corresponding to preset conditions according to a pressure signal sensed by the sensor module; and estimating means for calculating an angle value corresponding to the voltage value outputted by the output means, and estimating the center of gravity, wherein a body center can be estimated by obtaining an accurate detection using a small-sized system that has a relatively low-cost sensor module installed therein.
