FRT is a Godot "platform" targeting single board computers.
FRT does not need X11 to run, and should also run on raspbian lite.
Make sure that you have increased the amount of memory for the GPU. Some demos work with just the default 64M reserved for the GPU, but most of them will need more.
Download, uncompress, install somewhere in your path one binary from here:

For example:
$ unzip frt_093_214_pi1.bin.zip
$ sudo install frt_093_214_pi1.bin /usr/local/bin
