USB to Wireless to USB ... is it possible?

Is there any USB adapter that you can plug in your PC and will convert the USB output in wireless and then have a second USB adapter that will receive the wireless signal and reconvert it to USB input? The second USB adapter would preferably have to be relatively small.

UPDATE:

What I'm really trying to do is: a really long USB cable, but without the cable; in other words, "wireless USB". I'm trying to connect a robot that I built and that has a USB port. Of course, I could add a wireless interface but it'd be long and complicated... that's why I came up with this idea. USB hubs aren't really an option since the said robot has to move around.

Wireless USB hubs and extenders do exist (this hub, for instance) but they appear to be rather expensive. I would expect their to be noticeable speed and latency issues so I wouldn't want to run an external drive or video device using one, but for something like a printer it should work well (though for that particular use you might find it significantly cheaper+easier to buy a new printer with wireless built in and connect it to your existing wireless AP as a network printer).

I've recently found the answer, with the help of some feedback from my own thread (here).

To have the a USB device extended over the wireless network, you'll need something called a "virtual USB" setup. One service I've successfully used was VirtualHere (Windows compatible), with an alternative being USB/IP (more for Linux).

Essentially, the "USB adapter" you've mentioned would have to be a computer with WiFi capabilities; In the case of a robot, perhaps the WiFi-included version of a Raspberry Pi computer could do the trick.

I would say this is not simple to do for one reason - power supply. USB is in most cases used also to power the connected device. Imagine you would like to connect a flash drive this way. USB cable transmits 5V to the device so it can work. Using wireless dongle connected to PC would provide power to the dongle, but not to the remote USB (smaller plug for input to the usb flash disk). For this reason, such wireless USB cable would require its own power supply (eg. a battery, which will be relatively big and you would need to charge it often, or a wall plug).

If it capable of accept a USB wifi adapter use that to connect to it to your wifi. Then communicate over IP.

If not, you could strap a raspberry pi 3 onto your robot, and connect that to your wifi. Its will offer a large amount of functionality, including storing pre-built routines on the SD card. The Pi has USB ports so you can run a short 1 foot or less cable, and connect the 2 devices.

You then have to operate over TCP/IP.
