The invention provides a levelling carrying robot. The robot is mainly composed of a driving mechanism, a placing mechanism, a micro-sensing unit and a control system, wherein according to the drivingmechanism, two driving motors independently drive two crawler belts through different crawler belt wheels and are installed on the inner sides of side plates of the driving mechanism so that the transverse size of the robot can be effectively reduced, and the robot can conveniently move; the placing mechanism is installed on a side plate of a chassis through a rotary shaft, and the placing mechanism can be kept horizontal through angle adjustment conducted by a levelling motor; a driving device, a sweeping device and the micro-sensing unit are connected to the control system. The robot can stably climb stairs, and the horizontal state of the placing mechanism is kept to avoid the problems of falling of goods due to inclining and the like.
