Smart watch hearing aid ~

Program a smart watch to listen for specific voices or key words. Then
have them vibrate an alert until the person acknowledges it. Great use
for deaf people with children or grandchildren.

Sonic dispersement drone ~

Mount subwoofers on a box robot and have it play subsonic deep pitched
sounds to disturb people enough so they go somewhere to get away from
it. It could be autonomous and roll around a homeless settlement until
they leave.

Shoulder pad solar packs ~

Shoulder pads with clear pockets to solar battery bricks in. Perfect
for hikers and walkers to capture energy for their devices.

Screw drive pooper scooper ~

Tube with a motor connected to a long screw drive going down through
it. Put the tube over the turd and run the motor to use the screw
drive to lift the poop into the tube.

Powered by humans ~

Could you use virtual reality and make equipment with the necessary
stuff to harness the electricity in a human's motions and living like
they pretend to do in the matrix?

It's an interesting idea because then you could actually get people to
commit to staying in a pod for four hours selling their energy and
effort that entertained them the entire time.

Infrared stickers for robots ~

Use infrared or ultraviolet stickers to label walls and floors for robots to use for navigation.

That way you can put on the floor or on corners where they are and that the robot could read and if you concede to the stickers that I could figure out I'm here this is what I need to do to get horrible.

Just a thought. It's one of those things where robot vision and navigation is daunting for me and I just don't want to take it on. And if I could simplify that would me be clear some of the stuff out of the way for me to drive.

Because it could see things that we can see and then programming you would have to just teach it and tell it okay when you're here to get to this place this is what you do to get to that place this is what you do

You can even program and when to turn based on where those labels are where sees and ultraviolet barcode QR code or whatever.

Graffiti bot ~

Wheeled drone that has spray paint nozzles it can direct at a wall to over spray graffiti. Could be done weekly or monthly to give other graffiti artists a chance it to change pictures.
