Solve what?

You certainly wouldn't be the first to build a motorized tracking mount for astrophotography. There are plenty of existing products for manually-aligned star-trackers, and several still for "autoguiding" trackers that use the position of fiducials in the image plane. (These can use either a mirrored split in the optical path of the main imager "on-axis", or use a piggy-backed guidescope imaging system on the same mount.)

Check out high-gain, high-sensitivity imagers like the ZWO ASI290MM Mini, controller like the ZWO ASIAIR Pro, and tracking mounts like the iOptron CEM25P or Sky-Watcher EQ6-R Pro.

These are expensive, carefully engineered solutions, though. They don't really exist in the same market space as Dobsonian telescopes, and it wouldn't make any sense to make those tracking solutions twice as complicated and twice as expensive using by non-equatorial mounts.

I was unable to find a tracking solution for Dobsonian mounts. If they exist, awesome. I doubt a home-brew solution though would cost as much as the ones you identified.
