PURPOSE: A walking assist robot capable of efficiently keeping an electronic health record (EHR) is provided to enable safe and comfortable walking assistance for a user with inconvenient physical activity like an aged person, etc. in walking frame mode and wheelchair mode as well as to easily measure physical condition like the abnormality of a body, etc. by using various bio-signal measuring instruments mounted on the walking assist robot. CONSTITUTION: A walking assist robot determines a moving direction according to the operation of a joystick by a user in walking frame mode and wheelchair mode and assists the walking of the user by moving at a corresponding speed in accordance with a sensor signal generated from a strength sensor detecting the grip strength of the user. The walking assist robot includes multiple bio-signal measuring instruments (111-113), an information collecting terminal (110), and an information processing device (120). The bio-signal measuring instrument includes the following parts: one or more walking frame mode measuring instrument installed around walking frame mode joysticks (150,160,190) in order to measure bio-signals of the user in walking frame mode； and one or more wheelchair mode measuring instrument installed at a storage space (140) in order to measure bio-signals of the user in wheelchair mode. The information collecting terminal is connected to the walking frame mode measuring instrument through a cable, controls the measurement start of the walking frame mode measuring instrument, and collects bio-signals outputted from the walking frame mode measuring instrument, and is connected to the wheelchair mode measuring instrument through wireless communications and collects bio-signals outputted from the wheelchair mode measuring instrument.
