RTS2 is and will remain open-source. As that, there will be no fee for licenses, nor software upgrades. For the decade of its development, the project was supported through various funds, coming from public and private sources. We gratefully acknowledge those sources and they help getting the project up and running.
Support is provided on the rts-2-devel mailing list. On-site consultations are available and negotiable for reasonable fee.
