Fumik will help us to draw a decor picture on wall easier than ever!

The robot can draw a picture on a wall in size up to 5 meters in width and 3 meters in height. It is hung on a wall, traverses around to draw pictures, looks like a jellyfish is swimming. Fumik is an easy step to learn about robotics and make art work with it.

In August 2021, I got an idea to make a robot be able to draw pictures on a wall. After many days researching, designing, and programming, I finally finished a robot that could draw any pattern on a wall.

My key-point in design is using general parts to make robot, so end-users can easily renew parts if repairing is needed. Body frame, motor, bolts and nuts, … are all easily found on the market. Main controller is well-known PCB Arduino Mega compatible with CNC Shield to control two stepper motors that allow robot can traverse by belt.

    Step 2: Install the Robot - 1st Layer

    The first layer is used to install Arduino, CNC shield, power supply.

  • 3
    Step 3: Install the Robot - 2nd Layer

    The second layer will be installed motor, SD card.

    Stepper motor shaft will attachment gear; and (black) blank wheel will be shifted (manually) to keep the belt always contact with the gear.

Creating a wall drawing robot can be an exciting and creative project. There are several open-source resources and platforms available that can help you build your own wall drawing robot. Here are some key steps to get started:

Select the hardware: Choose the necessary hardware components for your wall drawing robot. This typically includes stepper motors, motor drivers, belts or gears for motion control, an Arduino or Raspberry Pi as the controller, and various mechanical parts like pulleys, belts, and brackets. Make sure to select components suitable for your project requirements and budget.

Design the robot: Design the mechanical structure of the robot using CAD software. Determine the size, shape, and dimensions of the robot based on your specific needs. Consider factors such as reach, stability, and ease of movement. Ensure the design accommodates the chosen hardware components.
