Gears

Generic Educational Autonomous Robotics Simulator

This simulator was created to allow anyone to experiment with robotics without owning a robot.

Try it out at https://gears.aposteriori.com.sg

...or the latest version from github https://quirkycort.github.io/gears/public/

It uses the Ev3dev api (...and some early support for Pybricks), so the code can run on an actual Lego Mindstorm EV3 if you have one.

Installation

The simulator is meant to be served through a webserver, and we maintain the site at https://gears.aposteriori.com.sg free for anyone to use.

If you wish to run your own local copy, download all files and put them in a directory on your server and that should be it. Due to CORS protection on web browsers, it will not work when served from a "file://" URL.

Without a Webserver

If you do not have a webserver, but have Python3 installed on your computer, you can try...

1. Download Gears from https://github.com/QuirkyCort/gears/archive/refs/heads/master.zip
2. Change to the "gears/public" directory
3. Run python -m http.server 1337 Do not close the window with the Python command running.

This should get the site running on http://localhost:1337 (...try http://127.0.0.1:1337 if that doesn't work).

The site may also be available to other users on the same network using http://your_IP_address:1337, where "your_IP_address" is replaced with your actual IP address. This may not work depending on your network configuration and your firewall settings.

If you do not wish to allow other users from accessing the site, you should run python -m http.server 1337 --bind 127.0.0.1 instead.
