@asvjerry stated " I’d be concerned by a runaway microdrone armed with a diamond tip running amok in a home. No telling what other grooves it might find groovy....*ouch* "
This is already with a proposal for the mitigation,
As stated " As for non contactless, I'm almost there, I've successfully encouraged a think tank with very knowledgeable individuals about my proposed design for an anchored Micro Drone with a undercarriage that is a Cartridge. "
One of the think tank is a neat whisky sipper, the idea of an alien object ending up in their Dram, was not to be tolerated, they would only continue with their contribution if the Micro Drone was tethered.
Tethering was deemed to be a little loose as control measure and was replaced with the anchoring concept as this gives a much improved control of a movement. iBut it is again proven - "Great Minds Think Alike", or "Birds of a Feather Flock Together".
It was not expected but requests for the Crowd Fund Link are now being sent
