Some users may wish to simulate a FarmBot without using a real FarmBot. Usually, this is done for the sake of software testing and development. FarmBot currently does not have a simulator, but it is possible to run a FarmBot without any motors attached. This means you can simulate FarmBot operations in software using only a Raspberry Pi, an Arduino, plus a few other supporting components.
FarmBot v1.2 is the easiest model to simulate because it uses off-the-shelf components and has a smaller form factor and lower power requirements than v1.4+ models. Even though v1.2 is not our latest model, it will respond to the same software commands as a v1.6+ device and is fully forward compatible with the Web App.
- A MicroSD card
- A MicroSD card reader
- A Raspberry Pi 3B or 3B+ and relevant USB power cables (~$35). DO NOT USE DIFFERENT RASPBERRY PI MODELS. They will not work.
- An Arduino Mega and relevant USB power cables (~$17).
- The latest FarmBot OS image file
- Create a new web app account specifically for the “headless” device. Do not apply power to the Raspberry Pi yet. Do not attempt to re-use accounts that you used with other non-headless devices.
- Select “v1.2” for the device hardware in the new web app account.
- Flash the latest version of FarmBot OS to the SD Card.
- Insert the SD card into the Raspberry Pi and apply power.
- Complete WiFi configuration steps and wait for the device to come online.
- (important) Disable encoders from the device settings page. This will allow for smooth on-screen movement in the Web App when simulating a device.
- The device is ready for simulation.
