CareRobots is an OpenSoruce project developed by Fab Lab UTFSM, LightHouse-DIG, Center for Engineering Education and Outreach and Soko Tech.
We aim to build low cost telepresence robots, that can be build in any Fab Lab/Makerspace around the world, this robot are intented to protect healthcare service personnel from the COVID-19 spread from infected patients.
1.0: This firmware is built for an Adafruit Huzzah feather ESP32, currently other boards aren't working with such reliability.
In Chile the router don't allow to acces them remotely, currently there are 2 firmware:
- WiFiClient, the firmware that operates directly to the robot.
- WiFiServer, a WebServer for http comunication, currently hosted in Boston in a ESP32, this defenitly has to change to gain more speed in the comunication.
For configuration the code has a configuration section, the user has to define:
- WiFi ssid and password
- Pins conected to the dc motor driver
- Motor speed
If you are downloading the softwares directlly you hace to coinsider that they are coded using Platformio, if you are using the Arduino IDE, you will find the codes in the src folder, they will titled as main.cpp (if you fill is more comftable, you can change the extension to .ino), and download the following libraries:
To install the NodeMCU in the Arduino IDE, you can follow the following instructions.
In order to make CareRobots easy to fabricate in any Fab Lab/Makerspace in the world, we only use 3D printers and laser cutters, all parts can be downloaded in the following link.
