Based on the problems of low automation of painting operation, uncontrollable painting efficiency and quality, and inability to guarantee the personal safety of painting workers in the existing high-altitude painting industry, the team designed a modern high-altitude exterior wall intelligent painting robot. The robot adopts an insect-like structure as a whole, the driving force is mainly provided by a motor, and the energy supply device selects a high-performance lithium ion battery. The work is designed based on bionics technology, using adsorption setae and electrothermal actuators to realize the wall climbing function. In painting, a five-axis mechanical arm with an industrial-grade air atomization spray gun at the end is used, which enables it to have higher working efficiency and flexibility, and to adapt to painting operations in dangerous and complex environments, effectively ensuring the safety of employees in the painting industry. At the same time, it is expected to change the situation of low efficiency and poor quality of traditional painting.
