A multi-leg independent mobile carrier device, comprising: a base (1), a traveling mechanism (2), and a posture adjustment mechanism (3). The base (1) is used for carrying a human being or an object. The traveling mechanism (2) comprises a driving unit (21) connected to the base (1) and a connecting rod unit (22) rotatably connected to the driving unit. The traveling mechanism (2) is used for driving the base (1) to travel and get over any obstacles. The posture adjustment mechanism (3) is connected to the base (1) and used for keeping the human being or object balanced. The multi-leg independent mobile carrier device integrates a traveling mechanism and a posture adjustment mechanism. The posture adjustment mechanism is used for keeping the base balanced all the time and the traveling mechanism is used for driving the entire device to travel and turn around more flexibly. Therefore, the technical problem of a carrier device being unable to satisfy requirements of good obstacle performance, comfortable riding experience, and flexible traveling is effectively solved. The obstacle crossing ability of the multi-leg independent mobile carrier device is enhanced, and user experience is improved.
