The present invention is an educational robot to which a structural module system is applied, and more specifically, an educational robot module that can be assembled to move a desired part by a user and an educational robot that can arbitrarily change the structure by a module unit.

The robot industry is attracting attention as a future-oriented industry along with IT, BT, and NT, and its size is increasing rapidly every year. In addition, unlike the industrial robots of the past, the present robot is characterized by intimate approach into human culture and life. Accordingly, there is a growing demand for robots and encouraging them to foster the robot industry. However, it is difficult for the general public to easily access robotics, which requires a lot of engineering knowledge.

The educational robot combines the academic and play areas so that the general public can easily access the robots. The robots create and use the robots by themselves, which naturally induces interest and affinity for the robots through play. Therefore, in addition to simply performing the desired function, the educational robot is important to make the connection between play and education organically by continuously inducing interest of the user and stimulating creativity.

In the case of the conventional educational robot product, the user can simply operate in a state where the structure is already completed, or the assembly method is limited even when the user assembles the robot, and the user only assembles according to a predetermined manual. In particular, the arrangement of the core parts such as the robot drive unit and the control unit is limited, and the freedom of assembly of the robot's appearance and additional functions is given. Accordingly, there is a problem that the degree of freedom of the user with respect to the robot configuration is low, so that the user's interest cannot be continuously induced and the user cannot exhibit creativity.

Therefore, in order to continuously induce interest of users and develop creative thinking, a robot capable of actively changing and assembling a structure in a module unit is disclosed.

Further, for this purpose, a robot module having a coupling unit compatible with the components of the robot is provided in a module unit and each module unit can be coupled to an arbitrary position of the base plate.

 A first aspect of the present invention is an educational robot product capable of freely changing a structure in a module unit, the base robot comprising a base plate and one or more robot modules, and a plurality of holes are formed in upper and side portions of the base plate. One or more robot modules are also formed with holes of the same shape and size as the base plate, and the base plate and the robot module are coupled and fixed by coupling means for connecting the holes. Here, the at least one robot module may include a driver module including a motor, and may also include a control module for transmitting a control signal for the motor according to an input from the outside. In addition, the educational robot product is characterized in that it further comprises a transmitter for transmitting a control signal to the control module.

According to a second aspect of the present invention, there is provided an educational robot module that can be assembled by adjusting its position according to a use purpose, wherein a support part of each robot module is provided with a hole, and the educational device includes a coupling means that can be combined with a base plate using the same. Module.

The robot module may be, for example, a wheel module having a servomotor, an arm module, or the like. The user transmits a control signal through the transmitter, and the control module receives the signal and transmits it to the driving unit, so that the user can control the robot module. In addition, the robot module forms a hole in the support portion, it can be coupled to the base plate formed with the same size and shape of the hole through a coupling means such as bolts and nuts. These holes are uniformly arranged on the upper and side portions of the base plate so that the user can fix the robot module at a desired position. Therefore, the user can configure the robot of the desired form by selecting the desired robot module and assembling it in a desired position according to the intended use.

Hereinafter, a preferred embodiment according to the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention having an arm module 3 (MANIPULATOR) and a wheel module 2 as driving units. 2 is a figure which shows the module located in this embodiment. In the robot of the present embodiment, a plurality of holes having the same size and shape are formed in the upper and side surfaces of the base plate 5. Modules coupled to the base plate 5 include a brain module 1, a wheel module 2, an arm module 3, a bumper module 4, a control module 7 and a battery module 8 and a cover 6. , 9) is combined with the base plate 5 to surround the module located inside the robot. In addition, various sensor modules may be combined in a desired place.

3 to 5 show each module used in the embodiment of the present invention. The brain module (1) is configured to use 4.3 inch TFT LCD, and the image can be realized on the LCD by using 1.3 M CMOS sensor. It is a robot controller that can directly control robots using CAN, SPI, UART, USB, etc., and can be used by porting the operating system of Windows CE and Linux. The user can use the OS-based program and control the robot using Bluetooth wireless communication. The same hole as that formed in the base plate 5 is formed in the lower surface of the brain module 1, and a user can arrange | position a brain module in a desired position using a bolt and a nut. In this embodiment, the brain module 1 is coupled to the upper surface of the upper cover 6.
