    Abstract: A manually propelled vehicle may include a vehicle body, a left drive wheel and a right drive wheel, a wheel driver that drives the left and right drive wheels, a sensor that detects a user behind the vehicle body, and a controller that determines whether the user is behind the left or right drive wheel based on a detected result of the sensor. When one of the left or right drive wheel moves backward and the controller detects that the user is behind the one of the left or right drive wheel, the controller suppresses or stops the wheel driver from driving the one of the left or right drive wheel.

    Abstract: To provide a walking assist device which can apply torque to a knee joint at a suitable timing. A walking assist device includes an actuator, a reaction force sensor and an angle sensor. The walking assist device is fitted to a user's leg. The actuator is able to apply torque to a knee joint of one leg of the user. The reaction force sensor detects a reaction force that the foot of the one leg receives from the floor. The angle sensor detects a hip joint angle of the one leg around a pitch axis. The walking assist device specifies a timing to start applying the torque to the knee joint in a direction that swings the lower leg backward, based on the detected reaction force and the detected hip joint angle.
