Description

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.

Details

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.

Components

1 × Arduino Mega 2560
1 × cnc shield
1 × SD card module
1 × Stepper motor

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.
