3D printed robotic desktop vaccum cleaner that can be controlled over bluetooth from an app. It should dock itself to a charging station connected to usb.
Interesting stuff... I have been working on a cannybot Logo Turtle recently.. it can be easily modified to create vaccum cleaner. See image below.. the base is 80mm in diameter. Can fit a small fan under the blue brain which will blow away the dust.
I have been thinking about how to use turtle design without much of a mechanical redesign as that's not one of my strengths. I think I am going to use a roll of blue tack or a mini lint roller fitted on an axle to the front/back of the device to roll and gather the dust! Just like a mini road roller and autonomously clearing up dust from my desk while I am away!
How about wireless charging using something like this?
