The man has an amazing and very useful ability — he can touch to find in the dark your sunglasses, smartphone, and other required items. Many engineers really want to equip this skill, their robots, but for learning artificial intelligence they do not have enough data about the shape of objects and their weight. Researchers from the Massachusetts Institute of technology figured out how to quickly and inexpensively gather the necessary information — they have developed a glove STAG, which collects data about the tactile sensations of the person.
Such gloves already exist, but with only 50 sensors and cost thousands of dollars. In contrast, the STAG made from available materials, equipped with tiny sensors 550 and costs only $ 10. It can afford even small startups are creating robots and prosthetic human hands. It is really a valuable invention, because in this way the robots will be able to get more dexterous manipulators and prostheses to gain more realism.
Cheap gloves for training artificial intelligence
Data collection on the form and weight of objects occurs in a predictable way — the man wears is connected to the computer glove and picks up a variety of items. The researchers tried to make the sample as diverse as possible, so that artificial intelligence had a wide range of knowledge.
Thus, the researchers collected 135,000 fragments of tactile data on 26 everyday objects, among which were soda cans, scissors, tennis balls and table accessories. Subsequently, the convolutional neural network used the information gathered to recognize specific objects — the accuracy was an impressive 76%.
In addition to data about the form of objects, glove raised 11 600 pieces of data about their weight. To do this, she recorded the pressure with which the fingers of the person holding each item with these data, the artificial intelligence has learned to identify many objects with an accuracy of 60 grams.
Equipped with all kinds of electronics gloves are created for completely different purposes. For example, in 2018, researchers from two universities have developed a glove that allows you to feel objects in a virtual reality. Read about this invention in our material.
