The AD-191 Robot kit helps children understand robot technology based on the useful and various assembly components such as CPU board, contact sensor board, infrared sensor, DC motor & servo motor, and remote control etc. In addition, it is not hard to assemble/disassemble at any time because it has a safe circuit module(welding is unnecessary). They can learn how to assemble & disassemble every kinds of robot, how to control the robot by their self- initiated programming skill. In the whole process of assembling & disassembling and programming activity, they can strengthen the spatial perception, develop the brain power and easily access to programming skill . This course helps students to learn basic knowledge of robotic assembly and the principles of electricity, electronic structure in the process of making their first robot. Students also can learn various types of components such as LED, Buzzer, DC Motor and basic function of Sensors. Apart from the robotic assembly, they can operate their robot by programming directly.
