Steel bar binding robot for building construction

The invention discloses a reinforcing steel bar bundling robot for building construction. In the scheme, the robot can freely walk on the surface of a reinforcing mesh, the diameter of the wheels can be automatically adjusted according to the size of an obstacle, normal passing can be ensured, meanwhile, passive clamping devices are designed at the bottoms of the wheels, under the action of the gravity of the robot, the bottoms of the wheels can firmly grasp reinforcing steel bars, stability in the working process is ensured, and the working efficiency is improved. And large positive pressure can also be provided through the design of propellers on the sides of the wheels, the binding device of the robot is ingenious in structure, the reinforcing steel bars can be rapidly bound, after binding is completed, the detection module detects the binding condition, and the self-rotating module can assist the robot in switching the walking direction. The steel bar binding robot integrates flat road surface walking, gr
