Robots

A robot is a computer-controlled machine used to perform tasks automatically. In this lesson, students will design and print their own head and body for a servo controlled ‘Desktop Robot’. While the project is intended to be a single lesson with 3D printing following the lesson, the project can be extended to a second lesson if required by connecting servos and programming the robot with Raspberry Pi, Arduino or Micro:bit etc.
