Abstract: An active rollator includes an auxiliary frame, a driving assembly, a sensing assembly, and a controller. The sensing assembly is configured to sense an operation area and output a sensing signal. When a user holds handlebars of the auxiliary frame and stands in the operation area, the controller is configured to, according to the sensing signal and a sensing threshold, control the driving assembly to make the auxiliary frame have a motion. Therefore, the active rollator aids the travel of the user.

Abstract: A linkage mechanism including a base, a first linkage, a second linkage and a driving element is provided. The first linkage has a first end portion and a second end portion opposite to each other, and the first end portion is pivoted to the base. The second linkage has third end portion and a fourth end portion opposite to each other, wherein the third end portion is coupled to the base, and the second end portion and the fourth end portion are coupled with each other. The driving element is coupled to at least one of the second end portion and the fourth end portion, and is configured to drive the first linkage and the second linkage to move relative to the base. A walking aid device is also provided.
