ODACO

Description :

ODACO consists of a personnal smart trainer that allows the user to live the whole experience of a private trainning session with adapted programs, posture detection and correction, voice commands and interactions with a simple and easy interface.

My contributions :

• Developing a voice assistant from scratch using python and Snowboy Hotword Detection toolkit.

• Integration of the voice assistant algorithm on Raspberry Pi while performing a Multithreading technique.

• Creation of the user interface Nvidia Jetson Nano board using python.

• Creation of gadgets to mesure biometric data of the user using Atmega328P microcontroller.

• Assuring the communication among different compartments via Bluetooth, socket communication and radio frequencies.

• Designing of all the electronic circuits of the system, based on AVR microcontrollers, with KiCad.

Hardware :

• THE BOX :

The box is the main part of the system.

It's based on 3 embedded boards :

• NVIDIA Jetson nano running an AI algorithm wich detect and analyse the humain posture.

• Raspberry Pi4 running the voice assistant algorithm.

• Arduino nano to communicate with the remote control, bandes and the posture belt.

Band :

Those bandes will vibrate when the person make a wrong performance. Its circuit is based on :

• Atmel microcontroller (Atmega328p) running at 8 MHz.

• RF433 radio receiver.

• Vibrator motor.

• Battery management system for 3.7v lipo battery.

• PCB View :

• Board 3D view :

Belt :

This gadget is used to get biometric data of the user and send it to the Box: Its circuit is based on :

• Atmel microcontroller (Atmega328p) running at 16 MHz.

• HC-06 Bluetooth Module.

• MAX30100 biometric (SPO2, Heart rate and Temperature .

• Battery management system for 3.7v lipo battery.

• Step Up Boost circuit (3.7V to 5V).
