Abstract: The present disclosure relates to a portable printer and a portable printing system including: a main body in a portable form configured to accommodate a cartridge including a nozzle that prints an image by delivering a printing material to a target having a soft or hard surface; a seating part that is provided to be exposed to an outside from a lower portion of the main body to face a surface of the target and surrounds the nozzle at least partially; a roller provided at each of the front and rear of the nozzle at the lower portion of the main body, based on a direction in which the main body moves along the surface of the target to deliver the printing material to the target; and a magnetic body configured to rotate in correspondence with rotation of the roller.

Abstract: Disclosed is an apparatus for running a physical software coding training book. The apparatus includes: a toy control unit being connected to a Micro Control Unit (MCU) via serial communication and controlling motion of a toy through the MCU; a training content processing unit being connected to the toy control unit via HyperText Transfer Protocol (HTTP) and providing training content written in HyperText Markup Language (HTML), the training content including motion control commands for the toy; and a physical software processing unit capable of directly writing block coding-based physical software by embedding a block code editor into the training content and performing control of the toy.

Abstract: There is provided an apparatus including a virtual machine unit for remote training, configured to implement a virtual remote training environment regarding physical software coding training between a student terminal and a teacher terminal, a virtual machine unit for remote control, configured to implement a virtual remote control environment regarding physical operation control over a physical device connected to the student terminal and to perform direct remote control of the teacher terminal, and a hypervisor unit for physical device control, configured to intercept the direct remote control of the teacher terminal over the physical device in the virtual remote training environment and to provide the teacher terminal with a right to control the physical device.

Abstract: Disclosed is a physical software coding training apparatus. The apparatus includes an interactive content management unit configured to provide interactive content capable of exemplarily representing at least some of a model source code controlling an operation of a physical device connected to a student terminal and overlaying a user input code on the exemplarily represented model source code, a teacher content control unit configured to assign a teacher terminal based on a type of the physical device when the interactive content is executed in the student terminal and to attempt a connection with the teacher terminal, and a student content control unit configured to force the student terminal to write the exemplarily represented model source code without any change when the connection with the teacher terminal fails.
