The new robot can learn from a demonstration and teach other robots what it knows.

Building a robot is hard. Teaching a robot is even harder. But teaching a robot to do your teaching for you might just be within the domain of possibility.

In case you’re building a robot to play out a particular task—like opening an door, for instance—there are just a couple approaches to show it. Most robots learn by means of movement arranging, where a software engineer indicates every development of the robot’s engines. A few robots can likewise learn by watching and emulating a human performing similar assignment.

Both of these strategies have their downsides. Mimicry is a quick strategy that serves a robot well when performing one specific task but costs the robot adaptability. On the off chance that a little detail is changed, for example, the sort or position of a doorknob—the robot needs to relearn the whole exercise without any preparation.

Movement arranging has the inverse issue: a wide range of conditions and circumstances can be modified into the robot, yet this takes a lot of time and effort. In the event that you need the most flexible door-opening  robot conceivable, you have to spend countless hours programming approaches to open many types of doors.

A group of analysts at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have built up an innovation that consolidates these two instructing strategies to take advantage of their strengths while avoiding their weaknesses.

Their innovation, called C-LEARN, empowers a robot to learn a task through mimicry and make an interpretation of that data into motion planning algorithms that different robots can utilize. Basically, one robot can learn a task from a human and after that show that task to different robots.

“By combining the intuitiveness of learning from demonstration with the precision of motion-planning algorithms, this approach can help robots do new types of tasks that they haven’t been able to learn before,” says researcher Claudia Pérez-D’Arpino.

In the first place, analysts give the robot data on the most proficient method to reach and snatch various distinctive questions in various diverse positions and introductions. This data frames a kind of “library” that the robot can go to when it has to know how to perform  a particular task.

At that point, the researcher exhibits the task they need the robot to perform, and the robot chooses sections from its “library” that contain the data it needs to perform that task. The robot then builds a motion planning algorithm that different robots can use to perform the same task.

In this way, the C-LEARN algorithm makes motion planning much easier. Instead of manually programming in a wide range of possible movements for every task, programmers can all rely on a single shared library. And because the movements a C-LEARN robot makes aren’t hard-coded these robots will be more adaptable and responsive to changes.

The next step for the C-LEARN team is to improve the algorithm to handle even more different circumstances, such as avoiding collisions and more complex multi-step planning. Eventually C-LEARN could be used to teach a wide variety of robots from industrial construction robots to bomb disposal robots.
