Setting up the Romi's Software

You'll only need to do this if your Romi is completely new, with no code or software whatsoever. If your team already has a functioning Romi, you can ignore this.

BalenaEtcher

BalenaEtcher is used to update the files of the Romi. There are dozens of programs that can do this— it's just that WPILIB as of 2025 recommends this one.

Here is its link:

  1. On the homepage, click on the green button labeled "Download Etcher".

  1. On the next page, find the installation compatible with your device.

If using Windows 10 64-bit or a newer version, (ex. Windows 11), it's recommended to stick to the installer download on the top.

  1. Open up the newly downloaded file and accept its Terms and Conditions. The file should start downloading.

Flashing the Romi's Software

Once all the software for the Romi has been downloaded, it is time to image the Romi with the correct firmware.

  1. Insert a Micro SD Card into your computer.

  2. Open BalenaEtcher. Your screen should look somewhat like this (note: this picture was from 2023/2024)

Once you're on the menu:

  1. Click "Flash from file" and select the downloaded image folder (from Romi Firmware).

  2. Click "Select target" and select the SD Card you just plugged in.

  3. Click "Flash!" and wait for the process to finish.

Once finished, insert the card into the Micro SD slot on the Romi bot.
