It's safe to say that any task which involves going up high is at least somewhat dangerous. The HB1 robot was designed with this fact in mind, as it climbs walls and even scuttles across ceilings so people don't have to.
Currently about to enter the market, the HB1 was designed by British startup HausBots, which is a University of Warwick spinoff company.
The robot itself has four rubber-tire-clad wheels, and is connected to a ground-based remote control unit via a 110-volt electrical tether. It can be equipped with up to 6 kg (13 lb) of attachments which allow it to perform tasks such as spray-painting walls, or performing both visual and ultrasonic inspections of structures.
The HB1 clings to walls, pillars, ceilings or just about anything else using two integrated electric fans. These draw air from beneath the front and rear of the robot, expelling that air straight out the back of the bot to create downforce. This setup allows the device to move across flat or curved, rough or smooth surfaces, and to roll over small obstacles such as electrical conduits which may be present on those surfaces.
HausBots is currently inviting prospective buyers to register for updates via the company website. The robot is presently being offered in Europe (at an undisclosed price), and should be available to North American buyers in the first quarter of next year. You can see the HB1 in action, in the video below.
