Robot for constructional engineering

The invention discloses a robot for constructional engineering. The problems that existing indoor wall face mortar smearing needs to be operated manually all the time, labor intensity is high, and efficiency is low are mainly solved. The robot for the constructional engineering is characterized in that a support comprises supporting rods (2), and the supporting rods are provided with an installation assembly (3) driven by a first power source (91) to ascend and descend; the installation assembly is provided with a movably matched installation beam (5); the front end of the installation beam isprovided with an action device (99); a swing device (4) and a telescopic device (7) are further included; the swing device is used for driving the front end of the installation beam to swing left andright; and the telescopic device is used for driving the installation beam to move forwards or backwards. The problem that the internal stress of an existing riveted hub bearing unit is uneven is mainly solved. The robot for
