I have a question of my own. Im working on a design project for school. The sponsor is giving us an M100 with the guidance kit and they want it to be completely autonomous and shoudl traverse an indoor greenhouse with the purpose of taking pictures of plants for later analysis. The biggest set back is 1. It must operate without the need of GPS and 2. My team consists of 0 computer/electrical engineers. The only one with a little experience is myself, which is limited to a few MatLab and Arduino project for a lab assignment. Any insight you have on how to handle this guidance/navigation problem would be greatly appricated. Thanks!

You can use vision to orient the drone and give commands to navigate using virtual sticks

For example see this article: A Novel Method for Indoor Navigation Using QR Codes

Please note that the Guidance SDK continues to work but has been deprecated many years ago
