Return back to Project Overview.
Hi guys! Today another major step for my Constructor! This time the back required some major tweaking, including the entire pneumatic flow. This coverage will mention the highlights of the changes.
Earlier this weekend, I've disassembled the entire back and start rebuilding it from its leftovers. This was done to improve the entire pneumatic flow. Previously, one of the pneumatic hearts (the Constructor has three hearts that creates the air pressure that's required) had some issues with providing enough pressure because of the weight. Because the weight will only increase in future progress, I had to redesign that heart - which also required me to redesign the entire back to make it fit in. This also gave me the opportunity to improve the back legs and access to the Mindstorms EV3 programmable brick.
The building of the front lid to access the battery box for the Power Functions LEDs has been resumed to fill in the gap that was previously notable when you look at the front. See the picture below to see how the angle in the lid shapes the face (front) more true to the source material. This was an intended feature for the lid back when I start building it in October - I just needed some extra pieces which weren't immediately available until recently.
The back section is slightly less durable than the previous one, however that's still bound to be changed. The Constructor now weighs 200 more grams than its previous version, which gives it a total of 2,7 kilograms. Despite that, the lifting of the Constructor now goes about fives times faster (and that's not a joke) and much more consistent.
Fun fact: I actually expected the Constructor to become 2 kilograms in my first post. It seems I'm way off from that, consider the body is still a frame (plating will be much later).
Pneumatic hoses are now fixed and clustered in the back with several Technic pieces, instead of being loose and creating a spaghetti.
Perhaps not really that important of a change, but the Constructor now tilts slightly forward, to match it more like its in-game appearance (see the picture above). I've added some extra parts for creating the body above the legs, as you can see on the picture below (thanks Lego® ZNAP again for those pieces!).
This is actually the first picture of the back, isn't it? It's actually a lot more eye-catching than the previous ones, which felt unfinished. Not that this one is finished either - it just feels a bit more reliable to me than it used to. Actually, there's more than meets the eye with the back, consider that the access to the programmable brick has been improved to an extent.
Instead of using a hinge to open the back, I've changed it with a multiple-point sliding mechanism. With the old system it became a hassle to reach the programmable brick, now it's much easier to access it. Next to this sliding mechanism, I've added some safety valves in case I would want to cut the air supply on the front leg and missile barrel.
That's it for today's coverage. I'll see you guys again next post!
