01 — Animatronic Ears- Prototype
The purpose of this project is to develop a prototype of animatronic ears using components such as Arduino, motors, and a variety of recycled and 3D-printed materials. Additionally, the intention is to accompany this prototype with a pair of gloves.
The inspiration for this idea arose from the acquisition of unicorn ears during a pride event, and the desire to transform them into bear ears that are capable of moving, thus providing a sense of excitement from them.
Once this prototype is successfully completed, there is consideration for the possibility of commercial production.
Materials
- Arduino Uno
- MPU5060
- 2 Servos
- Headband
- Faux fur for gloves and ears
- Cables
Since these materials will be used for the creation of the first prototype, it is important to emphasize that they may change as the project evolves. Some of these initial elements will be used due to the difficulty I face in finding the final products I desire, both in terms of appearance and functionality. Therefore, in this initial stage, I will work with these materials, and as I locate more appropriate materials, I will proceed to make the necessary updates.
Arduino UNO
Currently, I am using an available Arduino UNO as the main microcontroller for this project. This microcontroller will play a crucial role in the project’s operation. However, my long-term intention is to replace it with a more compact version that can be integrated more efficiently into the headband.

At the moment, I am powering the Arduino through the computer connection cable. However, in a later stage of the project, I plan to implement a power system based on rechargeable batteries to increase its autonomy and portability.
MPU5060
The MPU5060 will be the sensor responsible for capturing the orientation, velocity, and acceleration of the user. These data will be essential for generating the precise movement of the ears in response to the user’s movements.
Motors
In the current phase of the project, I intend to use a pair of Nylon motors, which are known for being lightweight and cost-effective. However, in a later stage, my plan is to replace them with more compact motors, provided I can find them in the market. This motor upgrade will allow for improvements in the efficiency and aesthetics of the final product.
Cables
For now, I am using jumper wires for quick connections on the protoboard, and soldering only for testing and experimentation purposes. However, in a later phase of the project, when I use an Arduino or another more compact microcontroller, I will ensure secure and permanent connections to guarantee the reliable operation of the system.
Headband
I am using a simple headband as a base, from which I will remove the cover, leaving only the plastic frame. This modification will allow me to secure the motors and ear structures more effectively. Later on, I plan to cover the headband with faux fur material to achieve the desired appearance.
Faux fur vest
I have acquired this vest from a second-hand clothing store. My plan is to use the vest to create the ear covers and also to make a pair of gloves that complement the design.
This post marks the beginning of the documentation of my project. Soon, I will share the second part, which will showcase progress on the circuit and the system functioning, at least in its basic version.
I am excited to continue sharing the progress of this project and see how it evolves in the upcoming stages.
