-
Emotional Display: The VoxHAUT features an OLED 0.96 inch display that visually expresses emotions such as happiness, sadness, and idleness. When users interact with VoxHAUT, it displays a happy emotion, creating a friendly and engaging atmosphere. In the absence of user interaction, the display shows a sad emotion, indicating VoxHAUT's longing for attention.
-
Audio Synthesis: To enhance the interactive experience, the VoxHAUT incorporates the JQ8400 audio synthesis module. It is capable of generating synthesized speech, sound effects, and music. This feature enables the robot to communicate with the user in a more engaging and expressive manner.
-
Environmental Sensors: The on-board AHT20 and BMP280 sensors enables VoxHAUT to monitor its surroundings. The AHT20 sensor measures temperature and humidity, while the BMP280 sensor provides atmospheric pressure and temperature data.
-
Obstacle Avoidance: VoxHAUT employs ultrasonic sensors to mimic the depiction of eyes and facilitate obstacle avoidance. By measuring the distance to nearby objects, it can autonomously navigate its environment, avoiding potential collisions. This safety feature ensures the smooth operation of the robot while ensuring the well-being of both the robot and its surroundings.
The primary objective of VoxHAUT is to provide users with a virtual pet experience through interaction with its Android application.
-
Pet-like Interaction: The primary purpose of VoxHAUT is to serve as a pet-like companion. Users can interact with the robot using the Android application, issuing commands, playing sounds, and engaging in conversations. The robot responds with synthesized speech, expressive emotions on the OLED display, and appropriate movements.
-
Environment Monitoring: The AHT20 and BMP280 sensors provide real-time environmental data to the Android application. Users can access information such as temperature, humidity, atmospheric pressure, and altitude, enabling them to monitor its surroundings remotely.
-
Speech Synthesis: The JQ8400 audio synthesis module enables the VoxHAUT to speak in response to user interactions. Using pre-recorded audio samples, the module generates speech, providing a personalized and engaging experience for users.
-
Emotional Feedback: The OLED 0.96 inch display serves as a visual feedback mechanism, reflecting the emotional state of the VoxHAUT. The display showcases happiness when the robot receives user interaction, reinforcing the feeling of companionship. When left idle for an extended period, the display exhibits a sad emotion, encouraging users to engage with the robot.
To get started, follow the steps below to build the robot:
- Wire up the components and follow the schematics, see next section.
- Run the
upload-firmware.batfile from the build/ folder. It should smoothly upload the codes to the ESP8266 NodeMCU. Make sure you have PlatformIO installed.
To build the Android app, follow the steps below:
- First, run the
npm-module-installer.batthen thebuild-sketch.bat, and finallyasset-mover.bat. All of which are located on the build/ folder. - Now, from the Android Studio, open the folder [src/app/Talk2VoxHAUT]. You can now build the project.
Happy building!
