A robotic assistant includes a base; an elevation mechanism positioned on the base; a display rotatably mounted on the elevation mechanism; a camera positioned on the display; and a control system that receives command instructions. In response to the command instructions, the control system is to detect movement of a face of the user in a vertical direction based on the images captured by the camera. In response to detection of the movement of the face of the user in the vertical direction, the control system is to rotate the display and actuate the elevation mechanism to the move the display up and down to allow the camera to face the face of the user during the movement of the face of the user in the vertical direction.

A robot includes a main body, a handlebar disposed on the main body and grippable by a user, a detection unit that detects a load applied to the handlebar, a moving device including a rotating body and moving the robot by controlling the rotation of the rotating body, and a switching unit that switches a support mode for supporting the user with walking. The support mode includes a first mode in which the robot autonomously moves to guide the user who is walking and a second mode in which the robot moves in accordance with a first load detected by the detection unit. When the robot moves in the first mode, the switching unit switches the support mode from the first mode to the second mode on the basis of the second load detected by the detection unit.

An apparatus is disclosed comprising an upper frame and a lower frame together connected by at least one lifting means, wherein the lower frame comprises two sidebars connected at opposite ends of a lower crossbar to form a “U” shape, wherein the upper frame comprises two handrails, each having a free end and an attachment end, wherein the attachment end of each handrail is rotatably connected to an upper crossbar, and the lifting means are disposed between the lower crossbar and upper crossbar such that the upper frame experiences a force exerted by the lifting means when the handrails parallel to a plane formed by the lower frame. In another embodiment, the apparatus is a walker having a harness in removable communication with the handrails.

The present disclosure discloses a method, a device of steering assist control for a walker, and a memory. The method includes acquiring a first moving speed of the left wheel and a second moving speed of the right wheel; determining whether the left wheel and/or the right wheel is in a steering state; calculating a steering angle estimate or a speed difference between the first moving speed and the second moving speed when in the steering state; acquiring steering assist compensations; and performing an assist compensation on the left wheel and/or the right wheel. The method can make the user more effortless when pushing the walker to turn, making it more convenient for users with less strength to use the walker, and reducing impact of the steering on the travel speed. Sudden stop caused by the increase of steering resistance can be avoided, and safety can be improved.

A bodyweight stabilizing locomotive device includes a frame configured to support locomotive movement and a stabilizing assembly carried by the frame. The stabilizing assembly has a first spring assembly with a first spring constant, a second spring assembly with a second spring constant different from the first spring constant, and a third spring assembly with a third spring constant different from the first and second spring constants. At least one of the first, second, and third spring assemblies includes lockout means which prevent extension of the one of the first, second, and third spring assemblies beyond a maximum extension.
