Climbing robot for movement on smooth surfaces e.g. automatic cleaning of horizontal/vertical surfaces has chassis with crawler drive suspended and mounted turnable about vertical axis, to detect obstacles and prevent lifting-off

摘要

The robot has a chassis frame (17) with suspended crawler drive (8), and e.g. a toothed belt (21) passing over a front and a rear deflector (20,19) with suction elements (12) to engage on the smooth ground (30). The crawler drive is mounted in the chassis turnable about an axis approx. at right angles to the ground. A lifting/suction device fastened to the chassis lifts chassis and drive on and off the ground. The device incorporates supports (18) with additional suction elements (9). All suction elements on the toothed belt adhering to the ground, are connected to common ventilation valves. The robot also has sensors to detect obstructions on the ground, and an inspection or cleaning module (7).
