I'm working on a concept that I think will work, but I wanted to check with people who understand more about pythonista's capabilities and wireless networks more before buying parts.

I'm working on a wireless video feed from a USB camera hooked to a rasberry pi as part of a robotics project. From what I've seen, I can hook the camera and a wifi dongle into a rasberry pi and create a wireless access point that my iPad can connect to. Then by directing a UI web view to the rasberry pi's IP address I should get the video feed. I'm new to networks, servers, etc, so I wouldn't be surprised at all to have someone tell me that I'm way off base.

Here are an article and a video that I'm basing my conclusions off of. The article is for using the pi as a wireless access point, and the video is for getting the video feed from the USB camera through the pi.

Thanks in advance for any help.

I think that is correct. Did you need to interact with the video in some way, or just display it in order to see what the robot is seeing?

If you have trouble setting the pi up as an access point, you could also have an external wireless router that acts as the AP for both the pi and ipad. But note that you don't actually have to set up a dhcp server or routing to ethernet for your approach to work.

The video feed is to see what it sees, though I'm hoping to add some computer vision abilities to it eventually. I also need to send navigation commands from the ipad to the pi through the same connection.

Seems perfectly reasonable. If you wanted to wait to buy the HW, you could probably work on the interface using the ipad and a laptop.
