Cubelets

Cubelets are a line of modular robotic construction toys manufactured by Modular Robotics. Cubelets are small robots that connect to create larger robot constructions, a kind of modular robot. Cubelets connect magnetically with data and power passing through a genderless connector. Cubelets are sometimes used in educational settings such as K-12 classrooms and museum exhibits.

Cubelets are a line of modular robotic construction toys manufactured by Modular Robotics. Cubelets are small robots that connect to create larger robot constructions, a kind of modular robot.123456 Cubelets connect magnetically with data and power passing through a genderless connector.7 Cubelets are sometimes used in educational settings such as K-12 classrooms and museum exhibits.

Operation

Each kind of Cubelet has a unique function and behavior. There are three categories of Cubelets8 - Sense, Think, and Act:

  • Sense Cubelets detect properties of the environment and turn them into data.
  • Think Cubelets modify and can share data throughout the robot construction.
  • Act Cubelets take the data they receive and turn it into action, like motion, sound or light.

In 2013 Modular Robotics launched the MOSS robot construction system,9 a line of construction toys similar to Cubelets. MOSS modules connect via steel spheres and magnets located at the corner of each module. Each module has a specific function and combines to create a variety of simple robots.
