An intelligent rollator has a vehicle body, a seat provided in the vehicle body for a person to sit or place items on, and front and rear wheels provided at the bottom of the wheels, driven by motors. A power-assist control method includes the following steps: obtaining the load weight of the vehicle body; and entering a first power-assist compensation mode to compensate the torque output of the motor according to a first power-assist compensation threshold, when the load weight is greater than a set threshold. The first power-assist compensation threshold is direct proportional to at least one of the following parameters: the load weight of the intelligent rollator, and the moving speed of the intelligent rollator.

Disclosed is a fall-resistant control method for an intelligent rollator, an intelligent rollator and a controller. The intelligent rollator has a vehicle body, front wheels and/or rear wheels configured at the bottom of the vehicle body and driven by a motor. The fall-resistant control method includes: recording the current position of the motor as the initial position when the moving speed of the intelligent rollator exceeds a first threshold and the acceleration of the intelligent rollator exceeds a second threshold; determining a first braking torque according to the position change of the motor relative to the initial position, wherein the greater the position change, the greater the first braking torque; determining a second braking torque according to the moving speed and/or acceleration of the intelligent rollator, wherein the greater the moving speed and/or the acceleration, the greater the second braking torque; determining the fall-resistant braking torque according to the first braking torque and the second braking torque.

An exoskeleton wheelchair system includes a base, one or more wheels coupled to the base, a body support connected to the base comprising: a back support; and one or more leg supports pivotally coupled to the back support, and a gait wheel linked with the one or more leg supports via one or more gait linkages and configured to rotate the one or more leg supports. The one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode. The back support is maintained at a fixed position relative to a location of the base when the one or more leg supports pivot about the first axis while the back support is in the standing position mode.

A robotic walking assistant includes a wheeled base having a base and one or more position adjustable wheels connected to the base, a body disposed in a vertical direction, positioned on the wheeled base and having a handle, and a control system that receives command instructions. Each of the one or more wheels is slidable with respect to the base between a retracted position and an extended position in a direction that is substantially parallel to a surface where the wheeled base moves. In response to the command instructions, the control system moves the one or more wheels between the retracted positions and the extended positions.

Embodiments of the present disclosure include a walker equipped with one or more sensors, an onboard controller, powered wheels and associated motor controllers. The walker can sense its distance from the user and activate the powered wheels when commanded by the controller. The controller can execute programming including an automatic feedback control algorithm that regulates the distance between the walker frame and the user. In this manner, the walker automatically follows the user, keeping the user from having to expend energy to pull the walker along. The walker can then be utilized by the user solely for balance and support.

An animal mobility device to be used with an animal who lacks full functional use of its rear legs, providing the animal with two modes of operation, with the first mode of operation being active, whereby the animal propels itself by its front legs while having its rear portion supported by the device, and with the second mode of operation being passive, whereby a human operator propels the device while the entirety of the animal is supported by the device.

A walking assistant robot, comprising a main frame body (1), a foot walking mechanism for alternating walking, an auxiliary device (2) and a control device; the walking mechanism, the auxiliary device (2) and the control device are all disposed on the main frame body (1); the control device is connected with the walking mechanism; the auxiliary device (2) includes auxiliary feet (201), and the auxiliary feet (201) are disposed in front of and/or behind the walking mechanism along the walking direction. The foot walking mechanism is used to realize the basic function of the robot walking forward; auxiliary feet (201) are disposed in the walking direction such that the walking mechanism still has, at the moment of foot alternation, multiple supporting points in contact with the ground. Therefore, the mechanism is slip-and-fall-resistant, stable and reliable and guarantees the user safety.

A walking assist device has a frame, a pair of right and left arm portions, a pair of right and left grasp portions, wheels including a pair of right and left drive wheels, drive units, a battery, a drive control unit, acting force measurement units that measure acting forces on the grasp portions, and holding units that hold the grasp portions at a predetermined position in the front-rear direction of the arm portions set in advance. The walking assist device travels forward together with a user. The holding units generate a restoring force for returning the grasp portions to the predetermined position. The drive control unit controls the drive units on the basis of acting forces calculated on the basis of detection signals from the acting force measurement units.

Methods, systems, and apparatuses are described that are configured for determining a path of an apparatus, engaging a motor to cause the apparatus to proceed along the path, receiving one or more of LIDAR data, ultrasonic data, or optical flow data, determining, based on one or more of the LIDAR data, the ultrasonic data, or the optical flow data, one or more objects in the path of the apparatus, and engaging the motor to cause the apparatus to avoid the one or more objects.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.
