Building wall painting robot

The invention relates to a building wall painting robot which comprises a vehicle body, a rotating table, a series-connection base, a middle series-connection arm and a terminal series-connection arm.A painting mechanism is formed by connecting a two-degree-of-freedom double-screw mechanism with a seven-degree-of-freedom mechanical arm in series, attached to the vehicle body provided with a differential mechanism and a reversing mechanism, has eleven degrees of freedom totally and is large in working space, flexible and intelligent in control and even and attractive in painting. Cameras at the four corners of the vehicle body can scan road conditions and wall surface information, automatic processing and trajectory planning are conducted by a processor, and thus automatic painting of different wall bodies is achieved. On the basis of openness of the multi-degree-of-freedom mechanism, different working heads are replaced, and different things such as roadside tree trunks and park fitness equipment can be paint
