Here’s something I’ve just finished working on. I call it the DB-Bot, inspired by the Dung beetle that collects manure.
The concept is a Robot Dung beetle drone that can be deployed in barren lands. It fertilizes soil with converted manure it collects from its surroundings.
This is revision 1, I wasn’t satisfied with the first version of the beetle, I wanted it to have the capability to fly, hence rev. 1 has rotors added.
