COMET is a cost-efficient, open-source Y6 hexacopter platform with a 3D-printed modular frame, designed for embedded and cyber-physical systems education and research.
Suggested by Robotheca, created by @uastw-embsys (opens in a new tab), from github.com/uastw-embsys/comet (opens in a new tab), pinned to commit 9837b8d (opens in a new tab). You buy the parts yourself; Robotheca doesn't sell robots.
The parts list is a spreadsheet in the repository. Robotheca can't read this file, so its quantities and prices are not checked here.

Buildable with some effort
How complete the published files are for rebuilding this robot, measured by Robotheca at commit 9837b8d. It isn't a rating of the robot. Counted out of 80 points and scaled to 100: the parts that don't apply to this robot are left out.
