Can you imagine that one day you walk into the classroom, your programming teacher pulls out a robot toy and says that it is coming to class today? This seemingly unrealistic idea is being implemented by Harvard University. Recently, Radhika Nagpal, a professor of computer science at Harvard University, used his own robotic tool Root to teach undergraduate students programming languages ​​such as Python and Javascript. 　　
It is understood that this robot named Root has been tested in the laboratory. From the appearance, the hexagonal Root moves a bit like a sweeping robot. It can be scrolled on any smooth surface, and it can be used to book, erase the blackboard, play music, and so on. The user can remotely control through the tablet, for example, to create a program that periodically draws an alarm when someone passes through the classroom.
Nagpal said that Harvard students use the Root simulation programming environment to achieve the purpose of learning. "They don't know how the sensors in the real world will behave in the face of different environments. The role of Root is to become intangible and tangible. Bring a more intuitive experience."
In fact, there are a lot of robot toys that can be programmed, but most of them are mainly for primary and middle school students, and the "programming" process of robots does not involve professional language learning. In contrast, Root is able to teach the basics of programming, while providing some sophisticated advanced learning, suitable for a wider age range. Currently, Root is priced at $199.
