The Seeds of Earth by Michael Cobley, which feels very much like he mashed together a couple of Alan Dean Foster books with an Iain M Banks Culture novel.
A key part of the story takes place on a planet-wide forest with giant trees and a Gaia-like sentience (Midworld), its maguffin is a galaxy-threatening superweapon (The Tar-Aiym Krang), and a significant character is a wise old floating robot/AI that uses fields to manipulate things (Culture drones).
This reminds me of Interstellar, where I recognised the books that the authors had taken their influences from, such as Rocheworld by Robert L. Forward, which also features helpful robots that fold up with arms that have smaller-and-smaller subunits.
