Codey Rocky consists of two different parts. Codey is the base of the robot, while Rocky is the mobile platform equipped with various sensors. From the age of six, children are able to create simple programs and solve problems independently with Codey Rocky. This is made easy with the mBlock 5 app, which simplifies the programming process. Users only need to assemble and configure pre-made blocks.

For signal processing and I/O, both Codey and Rocky have a range of modules available. Codey itself features two infrared sensors, an LED display with an integrated LED status indicator, light and sound detection, a speaker, a six-axis gyroscope, three buttons, and a rotary knob for simple commands. Rocky is equipped with a color sensor, an infrared proximity sensor, and a grayscale sensor. All modules can be read independently.
