Mosquitro Redesign: The Needle


  I spent some time today modifying the head of my mosquito model. After adjusting the lenses so the pole would be pointing outward, the whole shape appeared to nestle more smoothly into the gap designed for it.There was some adjustment needed but these were only a few tweaks. There does appear to be a fair amount more flow, however as the geometry for the eyes runs more in line with the cavity for the head..


  The next big challenge was the port for the mosquito's proboscis, which in the mechanical model would function like a powerful injector. I had a stroke of inspiration that the port would open up like a flower. The mechanisms for this however, might require some thinking as the needle would either push these petals out or they'd open out in preparation for the needle extending..


  The model is quite detailed, so I am planning to look into making a normal map for a simplified model for more full-body shots of the vehicle.

Mosquito Redesign: Working Legs


  I didn't have much success implementing an IK nor getting it to compress, but they say the simplest solution is often the most effective. In the case of my piston the simple solution was to parent each of the pistons with each other, tie them to 'aim' themselves at the opposing hinge and create a few driven keys to mimic the pistons extending and compressing.


  After that it was a simple matter of constraining each of the hinges. and the pistons so they stop at a fixed instance into and out of their sockets. By adding a fifth segment to the leg I am able to extend its reach to a motion window of between 92 and 168 degrees (any more open and the piston will collide with the knee hinge). Which might be one of them ore complicated elements of the model out of the way.


From what has been assembled so far, I think I can easily fit six of the legs into the main body with plenty of room to spare.
