I used to have the hots for a micromanipulator — a bulky block of clamps with a joystick that would scale down your movements from millimeter movements to tiny micrometer twitches for working at the single cell level. Now, though, I want these itty bitty microbots that you can suck up in a syringe and inject whereever you want, and command them to capture cells and move them wherever. Watch the video, and look at this little microbot that can grab single cells.
These are not at all autonomous. An operator manipulates them using laser tweezers (that’s what the ball-shaped blobs on prongs are for — you focus the laser on those like they’re little handles and control the gadget, like it’s on strings). The microbots look like they’re cheap and easy to make, too, using known techniques in microlithography used to make computer chips.
Unfortunately, what isn’t cheap is the laser-equipped microscope and the control electronics. I could probably buy a couple of Tesla Cybertrucks for the price of that gear.
