Usually payments from RoboSats are a few hops at most if you open a channel with WoS, Alby, ACINQ or some other similar large routing node. You can check out the channels that RoboSats has opened: https://amboss.space/node/0282eb467bc073833a039940392592bf10cf338a830ba4e392c1667d7697654c7e

With regards to opening channels towards the RoboSats experimental coordinator node, first check out the RoboSats documentation. Generally not recommended to open a channel towards RoboSats since its not a "routing" node: https://learn.robosats.com/contribute/liquidity/
