Robotic floor leveller

Hello folks,
Newbie here.
I am looking to make a machine which would grind a floor level.
I visualise a lawn cutting robot type of gadget with a grinding disc underneath.
Obviously, it would not be industrial size, grinding just a skimming off the highest spots first, working it’s way down the levels. Time is not a problem, it could be left working for days.
Any input gratefully received, any pointers to adaptable projects would be ideal.
I have lots of openbuilds cnc parts which could possibly be adapted to the project.
Thnx
Howard

Are you talking of removing bumps (but not hollows) from a floor that is otherwise level?

OR do you want to be able the alter a sloping floor so that it is level?

What it the floor made from? Concrete?

Removing bumps might be achievable with a device designed like the graders use for levelling road beds - they have a very long wheel base with the blade in the centre so the blade should represent the average height.

I suspect that the big challenge for anything more complex than that would be establishing and maintaining a point of reference. Perhaps a laser level could be used.

Hi Robin,
I made the mistake of using the inappropriately named “self levelling cement” on my workshop floor, so it’s not concrete. I really need a dead flat floor for my fabrication/carpentry projects.
I was thinking of using my laser level as a reference in some way and having a machine running in a grid pattern, skimming the tops of the high points until the floor was level.
My thoughts was for a wheeled device with a grinder mounted centrally on a leadscrew type device which would raise/lower the grinder with respect to the laser reference height.
I would lower the laser height a millimetre at a time so as not to stress the device.
Thx
Howard

If it's not concrete then what is it?

And you have not answered my question about the nature of the "unlevelness"

My guess is that it would be easier to lay a new level floor on top of the existing floor.

Building a complex machine for a single job is rarely a good idea - especially if you are not already an expert in that type of machine. For example, where are you going to test it and verify that it actually does what you want?
