I posted this very late last night so didn't add any description. I'll get round to that later today.
The main body is just a recoloured version of the 2013 LD01. As a variant of a construction robot the LD02 Fire Fighter is mostly a customised variant rather than a new build. Much like the original.
Principle changes from the 2013 LD01:
New arm design.
Now features "elbow" and flip out tool feature.
Colours changed to those of 2009 LD02.
Principle changes from the 2009 LD02:
Foot design is much larger for greater stability, and includes individually posed toes.
Unit is bulkier for greater protection from falling masonry.
Greater level of detail.
Arms feature converting feature to function as both hands/claws and as tools.
Principle similarities with 2013 LD01:
The main body, legs and head design are identical.
Principle similarities with 2009 LD02:
The colours are the same (blue "eyes", red and black body, grey pickaxe, white foam canister).
Curiously due to squatting stance they are the same height.
Do I like the new version?
No, I love it. The design choices are in line with the thinking behind the original, namely "take a design intended for working on a building site, and convert it for use as a fire fighter".
What do you think works?
For me the flipping tool idea worked brilliantly. I've seen it done before in various toys and MOCs, so I'm not going to claim I "invented it", let's face it, it's the idea behind the Swiss Army Knife, but it works so well here.
The colours say "fire engine" and that makes the build very true to my original vision.
What didn't work?
I'm not sure I'd have kept that foot/leg design had I had a little more time to fiddle.
How does it compare to the original:
The original seems sleeker and closer to human proportions, which for a fire fighter might be more practical. But at the same time I can imagine the original getting trapped under fallen concrete beams or simply making a path for human fire fighters to do the actual rescuing. The newer design, while probably having a harder time navigating in confined spaces, wouldn't be as likely to get trapped under falling rubble and could lift a body to safety.
Is there a back story?
Not at present. This was a proposed sideline which existed briefly on LEGO.COM in their designByMe galleries, but was dropped in favour of more CyberAgent designs. "Will I create on in the future?" given time sure, in fact I might knock one out later today.
How does the new design compare to your other, recent, designs?
In my honest opinion, this is probably the first "to order" design I've done. While my more recent Changeling designs were deliberately made to a specific set of criteria, this was the first deliberate recreation/reinvention that didn't specifically change the original function as well as the aesthetic.
Engineering wise it is the combination of just about all my ideas together. It will, more than likely, influence future CyberAgent and Steam Knight designs.
And for once, no wings.
Is this likely to turn up on Cuusoo?
Erm... I'll have to think about how it might be marketed in terms of a "theme". Certainly "LD Series" doesn't have a ring to it. Generic robot and mecha designs are very common on Cuusoo, to stand out you need a hook, a back story or to hijack a known brand.
So the simple answer is, probably not (yet).
Are you going to do more like this?
As I said in the introduction I'm only doing this because I'm on hiatus from active MOCing, the plan WASN'T to build NEW designs at all, but to showcase some forgotten older ones. I may continue to promote the remaining LD units (I think there were about 12 in total) but whether that will translate to 12 updated designs depends, on both a combination of time and ideas.
Some of the other LD series units were military rather than civilian designs. I'm not entirely sure the modern frame lends itself to military designs (such as VTOL attack drones and tanks).
2013 V 2009
The original design was a redesign of the 2009 LD01, intended for use by the Fire Department for rescue and fire fighting missions.
Principle differences from 2009 LD01 and LD02:
The foot/lower leg was almost completely redesigned. The intention was to create something more "agile" looking. It had the unexpected side effect of making the unit taller.
The claw like hands were replaced with fire fighting tools, namely a pickaxe (standing in for a standard fire axe) and a hose with under-slung foam canisters.
The colours were changed to evoke a "fire engine" over the construction vehicle yellow.
Principle similarities between 2009 LD01 and LD02.
To be honest the main frame is identical. All the main joints are in the same place and just the rear detail, legs and "hands" were changed.
What do you think of the 2009 version now?
To be honest the only thing I ever really wanted to change was that waist. Had I been able to come up with a way to attach the main body to the hips without using that 1x1 tile with clip piece I would have. But DesignByMe was limited in the parts available in those colours in 2009, plus I wanted to upload it to the gallery and had I changed it to a red 1x1 brick with studs on all sides, I would not have been able to upload it.
Quoting David Roberts
The flip round hand/tool attachments are a brilliant bit of design work.
Like I said in the comments under the original, I felt the lack of hands/claws would be a problem for a fire fighter robot, sure he can break down doors and put out the fire, but how is he going to lift fallen debris? or pick up an unconscious trapped human? The flip out hands seemed like the best compromise. I had also thought of using multiple limbs, but in the end I wanted to retain the same basic frame.
