Industrial Drone

This is actually from one of my work-related projects. I was to create an image of a humanoid "Industrial Robot" in a fantasy sci-fi style for a national robotics contest (Kontes Robot Nasional). They say it have to be humanoid and sci-fi looking, yet represents a robot from the "industrial" category of the contest. So I went and create this drone, carrying a cake like object (which is actually discs used for the Industrial Category contest, the contestant's robot was supposed to carry and reorganize this disc blocks).
