Abstract
The present invention relates to a walking assistance robot load compensation system which cancels out the load of a walking assistance robot worn by a walking trainee, the walking assistance robot load compensation system comprising a dynamic compensation part compensating for changes to a dynamic load according to the displacement or the inertia of the walking assistance robot, the dynamic compensation part, which may compensate for a changing dynamic load of the walking assistance robot, comprising: a first plate which is movable in association with the displacement or inertia; a second plate which is spaced apart from the first plate and is movable in association with the walking assistance robot; a connection wire which is connected to the first and second plates and movable in association with the first plate and the second plate; and a dynamic compensation unit which applies resistance force to the connection wire to suppress changes to the dynamic load of the walking assistance robot.
