Sure.
Right now, Opentrons rules with their open source robots, so liquid handling robots are pretty well handled. Xarm makes good arms for interfacing with Opentrons, so then it comes to everything else necessary to get to full automation.
1. Automated plate hotels
I need plate hotels to storage samples that interfaces with my robot arm and robot systems. This I'm basically using Theo Sanderson's designs for this https://www.thingiverse.com/thing:2668120 since buying them commercially is so darn expensive. I really need this for my system, so I am building em.
2. Plate sealer / unsealers
My entire full automation pipeline is built around NOT needing a plate sealer or un sealer (something you can't do with the vast majority of screening systems). Automated versions of just the sealer itself cost more than 2 liquid handling robots and a robotic arm combined (and all it does is seal plates!) I think there is an opportunity for building simple but effective automated plate sealers and unsealers.
3. A train system
I think Concentric (Ginkgo's COVID company) uses something similar, but basically a system that can use small trains to bring plates and reagents around a lab to different robotic stations. I'll probably just do that with lines of robotic arms, but I definitely spent quite a bit of time thinking of how to do this. (in my factorio megabase I really learned how to route trains, and I think it's exactly the same problem I face with my robotic work stations). I'm not sure how to scale the selling of that though.
