Description

{ASSEMBLY KIT FOR PHYSICAL COMPUTING EDUCATION}

The present invention relates to an assembly kit for learning physical computing.

Recently, there has been a lot of Physical Computing learning for general people or students.

The term "physical computing" is used to construct a computer system that interacts with a person using a sensor as an input device, a motor and a microcontroller as an output device, and particularly, an explosion of an open source hardware called Arduino Respectively.

Arduino is an open source computing platform and software development environment based on simple microcontroller boards, a tool for creating interactive objects and digital devices that can sense and control the physical world. At this time, open source means free source code or software.

Physical computing can easily create interesting works through various input sensors and output parts, so it can be easily learned by ordinary people and students. Drone and robot can be realized as well as real life and practical part. As the demand for learning of this computing increases, drones and various wireless control toys and kits are being sold.

Drones refer to airplanes or helicopter-shaped airplanes that fly by induction of radio waves without people burning, and are mainly used for military purposes. Recently, however, they have been used for various purposes in the private sector.

However, the existing drones are small in number and do not vary in number of products produced to suit the teaching of physical computing, and most of them are configured to move according to a predetermined program, so that various programs for controlling the drone can not be applied, There is a problem in that it is not easy to develop a drones-related program suitable for the drones.

In addition, since the microcontroller board used for the drone can not be used together with other uses such as robots, it is inconvenient to make each necessary board.
