This is a code project for an ankle rehab robot

AnkleRehabRobot

This Project aims to deliver a cheap and open-source rehabilitation robot for the ankle

Components:

• Computer: Nvidia Jetson Nano
• Microcontroller: Arduino Mega
• Interface: LCD Touch Screen Actuators: DC Motor Self-Locking Worm Gear Motor with Encoder
• Motor Driver: L298 Dual Bridge
• Voltage Regulator: 12/24V to 5V
• Limit Switches
• Power Supply: 24V

System Architecture

Here we can see the distribution of the applications and responsibilities. The python program on the Jetson Nano runs the user interface and handles serial communications, data processing, and data logging. On the other side, there is the Arduino with its C-based code that listens for the command of the jetson and runs a closed loop position control based on the encoder read of the code.

Installation

For the installation of this project:

1. Clone this repository
2. on the root of the project run: pip install -r requirements.txt

Arduino Setup

Figure: Arduino Motors Wiring Diagram

Open the folder arduinoRehabAnkle in either ArduinoIDE, PlatformIO or the desired editor and load the [code](arduinoRehabAnkle/rehabAnkle.ino) into the development board

From here you should determine the serial port that the arduino takes in the raspberry pi, run the following command: - ls /dev/tty*

Test Project

To test this project open a terminal on the root of the folder and run:

• python src/rehabGUI.py
