The robot learned to copy the human handwriting and drawings
The ability to write words on paper seems like a pretty simple human skill, but in fact it is extremely difficult. Just think - to learn to write, you need to understand at what point you need to lower the tip of the pen, for how long and in what direction to drive the line, as well as where to stop. Despite this variety of activities, researchers from Brown University was able to teach the robot writing, and now he can quickly pull on the blackboard the words in different languages, and even a simple copy of the picture.
The author is embedded in the robot's algorithm is a student named Atsunobu Kotani. That his work has allowed the robot to figure out what kind of strokes and in what order you need to do to draw on the blackboard certain Japanese characters. Established training system consists of two models: a "local", where the algorithm monitors the current position of the pen, and "global", where he is responsible for the transition to the next letter.
The robot and the human skills
To test the performance of the algorithm, the researchers conducted a test - they wrote on the Japanese word for the board, and allow the robot to copy it. The algorithm showed his best side and, though made mistakes in the order of strokes, the characters written by him were quite legible.
After a successful test in the Japanese language, the researchers tried to trick the algorithm by writing on the blackboard the word "hello" in ten languages, including English, Greek, Hindi, Urdu, Chinese, and Yiddish. To their surprise, the robot even copied them without any problems, and in the case of English, he was even able to draw cursive handwriting. The only problem is that the algorithm is not able to copy the Arabic language, where the letter is right.
After that, the researchers gave the robot even more difficult task - they asked him to copy the handwriting olds. When he has successfully completed the task, and it became clear that he could even copy drawings. Researchers have not lost - a robot really was able to draw a simple picture of the Mona Lisa.
A new study has erased another line between humans and robots. In 2018 robots have learned to talk like humans, and even book tables in the restaurant - it seems that in the near future they will learn and writing.
