A robotic digger appeared, which autonomously searches for mines

The researchers explained that robots can autonomously find objects that are in plain sight. However,

devices have problems when they need tolook for objects that are below the surface of the earth. Robots must feel their way through sand, and wireless technologies such as radar provide only a vague idea of ​​what lies below. Now, researchers at the Massachusetts Institute of Technology (MIT) have created a robot that can sift through granular material such as sand and find objects.

The machine is an improveda version of the earlier tactile sensor, in which a transparent gel was combined with a reflective membrane - it flexed on contact with objects. LEDs shine through the gel onto a membrane, and a camera captures the reflection to help computer vision determine the three-dimensional shape of objects underneath. The robot distinguishes sand from the object it needs to remove.

The new robot is thinner and simpler, itmoves thanks to a robotic arm, as well as vibrations that help him poke around in the sand. He can turn and move differently to get an idea of ​​the size of the object.

Researchers say they need to do moreseveral improvements - for example, setting up motion to detect different substances. However, scientists already now suggest that it can be used to find mines, and in the process people will not be endangered. They also added that the device is easy to use in large scale archaeological operations.
