Engineers from a small company Grabit developed a mechanical arm with a unique mechanism of capture objects.
Unlike analogies, this unit uses the principle of electrostatic attraction.
If you are not familiar with this term, the idea of it may be obtained by rubbing a balloon on your hair, and then attach it to the wall, where it will hang.
A feature of the device is the ability to capture the soft or fragile objects, however, a small weight.
With the example of the operation of the device can be found on the video in the continuation of the post.
