PURPOSE: A motor trouble sensing device of a feeding assistance robot is provided to reproduce the same motions by arranging the motion history of a motor. CONSTITUTION: A feeding assistance robot (100) comprises a motor (110), a current detector (120), an abnormal current determination unit (130), a current cut-off unit (140), and an error display unit (150). The motor rotates a predetermined shaft by using the supplied current. The current detecting unit generates a current detecting value by detecting current supplied to the motor control unit controlling a motor or current. The abnormal current determination unit generates a current signal by comparing a current detecting vale with a reference current value. The current blocking unit blocks current supplied to the current and motor control unit when an abnormal current signal is received. An error display unit outputs an error mark when the abnormal current signal is received.
