Introduction
VT-61 is one of the main characters of a short film we are working on. In this section I should explain a little of his life to give you a better understanding of him.
He lives in a planet where only robots can survive and the only way to stay alive is by keeping themselves full of the only energy provided by the nearest star in their galaxy. The VTs are the guardians of that planet; they just protect their most valuable source of life.
There is a more detailed and deep story about him and his environment, but I think this is a good start. He has propellants not to fly but to jump like a jetpack. So, keeping that in mind, let's go and start his creation process.
Concept
First of all, it is very important before starting any 3D work to previously have as many sketches as necessary to be 100% sure you know what to do in 3D. As we always say, "Design on paper, not in 3Dā. Well, here are some of our sketches (Fig.01) and the final concept painted in Photoshop (Fig.02).

Base Mesh
Since he is a robot with uncovered mechanisms and pieces, I did some research on the internet and found some pictures of pieces that I used as references for him (Fig.03).

I modeled each piece as shown in the following images (Fig.04 ā 06).
