“Now let’s not reinvent the wheel”, the wheel is reinvented over and over; but in nature, not too many wheels are there ? no rotating parts, at least parts which go all the way around… nup… man invented the wheel it seems, and loves to continue doing it.. so my more recent advice is: ‘why not, go ahead ! make a great wheel, but make sure you invent the axle first…”
You know the weird thing about a hummingbird robot, is that at this stage, it might be easier to get a camera and transmitter, and train a real hummingbird. At least if it is in danger, a real hummingbird would fly somewhere else, not sure about the robot, the real hummingbird will last longer, and probably fly much more .. stealthily…
Find a way to transmit the visual cortex signals of a real hummingbird to ground… then train the hummingbird.
Find another hovering bird, which is smarter and more trainable than the hummingbird..
Make a robot to follow the hummingbird at a distance… with the camera on the hummingbird etc..
I travel, and my stories are a bit Arabian Nights, without the fun bits .. lots of majik carpet planes, hotels, and cabs and roads.. going to sleep and waking up at 2, or 3, or 1 , or whenever for a week or so, then re-crossing the pacific ocean to do it all again..
