Executive Summary
Image of mask. To be replaced with actual project near completion
A humanoid talking robot head.
The head listens to you with a microphone, formulates a response, and then replies using speech synthesis while moving its mouth.
Currently, I have PWM working on the beaglebone along with servo control (with a circuit for a high-torque servo), a rudimentary speech synthesizer, and speech recognition.
The primitive chat-bot and the mouth are not working.
An example of a much more complex version of what I'm aiming for can be found here. At a minimum, this robot will respond to some speech input, move its mouth a bit, and output some speech output. If I can't build a complex chat bot in time, that's okay with me. I plan to focus on the other three parts more than anything else.
Packaging
If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.
Installation Instructions
External Hardware
Obviously, there's a beaglebone
The dowels and wooden base are used to make a framework for holding up the mask as well as holding the beaglebone.
Another dowel is attached to a servo, which is attached to the central dowel. I used a 5V 20kg servo because of the weight.
The motor's dowel is also connected at the other end to the base of the jaw so that the mouth can be opened.
Beyond the structure itself, one needs a microphone. I used a Logitech usb microphone that was made for the game rockband.
You also need a speaker. It can't be usb or use bluetooth over usb as the microphone is using that.
Software
First, make sure you have Python 3.7
If you don't, then you can install it with:
sudo apt install libpython3.7-dev
If it gets deprecated, you can update the versions in the Makefile, or build it from source using the instructions here.
Afterwards, you're ready to install the program
Here's the installation commands for installing the Mandroid software:
git clone https://github.com/blueOkiris/man-droid sudo apt install -y libsdl2-dev libsdl2-mixer-dev python3-pyaudio pybind11-dev flac pip3 install PyAudio pip3 install SpeechRecognition make sudo make install
Here's the explanation:
- Download from git
- Install Dependencies:
- SDL2_mixer is required for speech synthesis: `libsdl2-dev libsdl2-mixer-dev`
- The Python pip libraries `PyAudio` and `SpeechRecognition` is required for speech recognition. It relies on: `python3-pyaudio`
- The python speech recognition library is called in C++ using pybind: `pybind11-dev`
- Flac for audio input
- Build with make
- Install system service for running at start
User Instructions
Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.
Consider making it autostart for full credit.
Highlights
Here is where you brag about what your project can do.
Include a YouTube demo the audio description.
Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.
Work Breakdown
As the only team member, I did all of the work.
The project can be broken up into four main sections with subsections.
- Servo/Head control
- PWM Control
- Speech Recognition
- Speech Synthesis
- Recording sound files
- IPA map to sound files
- Synthesis object with instance of Servo
- Brain (Chat-bot)
- Tie it all together
- Process inputs and produce sentences in IPA as response
The only thing really unfinished is the brain, though the synthesis can also be improved.
Future Work
Suggest addition things that could be done with this project.
Conclusions
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
