The 3d image shows a vehicle with small ducted fans for lift, and minimal aerodynamic lifting surfaces.
Helicopters use very large blades because (for very basic physics: momentum goes as MV, power goes as MV^2) it is more efficient to move a lot of air slowly than a little air quickly. So it will need more power than a helicopter which will make it less efficient, noisier, and the down-wash will be more damaging.
There may be a few applications where the lack of exposed blades will help, but not many. Even if the blades are enclosed, the very high power downwash will prevent landings near anything even slightly fragile.
Helicopters look the way that they do because that is the best design.
Small quad-copters make sense in applications where efficiency and noise are not critical.
Self flying is great, but that technology is mostly available now anyway
