Abstract:
1. A multi-sensor signal processing system for driving a left motor supporting walking of a left foot and a right motor supporting walking of a right foot, the system comprising: a communication unit configured to receive a first sensor signal corresponding to a force applied to a left palm, a second sensor signal corresponding to a force applied to a right palm, a third sensor signal corresponding to a force applied to a left sole, and a fourth sensor signal corresponding to a force applied to a right sole, in real time through one of a wireline communication method and a wireless communication method; a sensor information processing unit configured to receive the first to fourth sensor signals, compare a size of any of the first and second sensor signals with a pre-set threshold value to determine if there is a walking intent, and output a first walking intent signal in response to the third sensor signal and output a second walking intent signal in response to the fourth sensor signal when it is determined that there is a walking intent; and a controller configured to generate a first driving signal in response to the first walking intent signal to drive the left motor and generate a second driving signal in response to the second walking intent signal to drive the right motor.
