A robot appeared that can cling to the ceiling

Researchers from the Laboratory of Bioinspired Robotics and Design (USA) presented a new

the design of a robot capable of adhering tosmooth surfaces using a vibration motor attached to a floppy disk. According to research, a fluid-mediated adhesion force between the oscillating disc and the surface is at work in the design of the device. The robot, created by the researchers, is equipped with a flexible disk with a diameter of 14 cm, which vibrates at a frequency of 200 hertz.

This vibrating disc can create a thin layerlow pressure air between the disc and the surface to which it rests. The air layer is less than one millimeter thick, but it is able to withstand a 5N force acting on it. This process creates a suction effect that does not require the disc to be constantly pressed against the surface.

Since the robot does not require constant adhesiondisk to the surface, it can move without breaking adhesion. The researchers have created a robot with significant advantage using the new system because it is as simple and cheap as a robotic climber with a smooth surface, and can be produced on a smaller scale. However, the project team recognizes that there are flaws in the design.

The biggest drawback is noise.200 hertz is the frequency that a person can hear. In this case, the robot must be in working order, otherwise it will fall. Scientists working on the project also note that the robot shown in the video is the optimal size for this technology. Downsizing means that the motor makes up a disproportionate proportion of the overall weight of the unit.
