I don't want to be too negative, but all your demos seems extremely silly.
Sure, the package is really interesting and definitely got me interested. But not one of the demos seems like a good use of the hardware. If you want to position yourselves mainly as an educational tool I don't think that is a problem. But if you want to target the 'maker' community I think you should put some thought into that.
For example, you could change the 'security guard' demo into a 'housekeeper' demo. You make it roam your house during the day and keep an up-to-date list of things you need to buy. I think this should work reasonably well for laundry and cleaning products. And after you have some historical data you could even do some forecasts about when you need to buy things again.
Another example would be to have it integrated with weather data and when it starts to rain it goes around the house to check if all windows are properly closed. On this same note it could keep track of the window state during the day and send you a reminder to open/close some windows if the temperature/humidity is above/below some threshold.
I think that by having some more 'useful' examples you should be able to get more attention from the 'maker' community. My guess is that a lot of folks that are heavily into home automation would love to have a device like that help with random things around the house.
Best of luck with your product, and I hope you succeed because this idea looks really exciting.
This does not sound negative to me and actually is great to read because this is definitely in the list of potential use-cases so we could make a video for it!
As for humidity, we don't have a sensor for it yet BUT the platform was made to be extensible specifically for this so it's easy to add one (see https://docs.innate.bot/main/robots/mars/extending-mars)
Thank you!
