Abstract
A walking assist cart includes a cart body on which a load can be placed, a drive portion that drives a drive wheel, an inclination sensor that detects the inclination angle of the cart body, and a controller that acquires the weight of the load placed on the cart body based on the drive force of the drive portion and the inclination angle of the cart body and outputs assist drive force based on the weight of the load that is acquired.
