Visible Vocal - A SOUND-CONTROLLED ROBOT DRAWING CAR

‘Visible Vocal’ is a sound-controlled robot car, which allowed people to paint through their voices. The project aims to raise the awareness of providing equal educational opportunities to children with disabilities.

In this project, the sound-controlled robot car allowed children who had lost their arms to paint through their voice and make their “painting aspirations” get actualized again. Although it was not perfect and I did not have time to optimize the device, I still appreciated the opportunity of taking a small step to help the disabled at such an early stage of my career. I was grateful that it became a discussion topic in the community so that more people could understand and start to invest in Accessible Design and Inclusive Design.

How it works?

The project was created with an Arduino, a sound sensor, two motors, and several 3D-printed parts. After brainstorming with my teammates, I created a 3D model in Blender to visualize the idea of the drawing car. We used a laser cutter and a 3D printer to create the main parts of the device. For the software, I programmed an Arduino to collect the user's voice through the sound collector fixed on the top of the car. With the user's directed instructions, the car would move to the left or the right. With different volumes of the sounds, the car would change the intensity of the paint on the paper.
