Pneumatic wall-climbing robot

The invention relates to pneumatic wall climbing robot. It is made up of forefoot, back foot, and turning step motor decelerated assemblies, sucking disc, sucking bracket, cylinder, air passage control unit. The forefoot and back foot step motor decelerated assemblies is formed by decelerated unit and stabilizer extending means. The turning step motor decelerated assembly is formed by step motor, harmonic reducer, and a pair of bevel gears. The step motor can be used to drive the robot rotate from 0 degree to 360 degree around the back foot bracket center. The robot goes forward or backward relied on cylinder stretching of between the forefoot and back foot.
