The world as we know it is destroyed. All that's left is the wastelands of a civilization that once thrived. But for us who have survived the fall of humanity, we need a vehicle that can bring us to safety - and help everyone else do so. It is the Halftracker. This is my submission for the TC17 contest. As the name suggests, it is a half-track. It will have a claw arm attached to the roof of the truck. The arm will have full 360 degrees of rotational freedom, but unfortunately this means only two functions can go through the turntable. The functions/features I am considering for this model are: Driven tracks (uses an individual L motor on each track as opposed to a differential to prevent slipping) Steering on front axle Oscillating front axle (with shock absorbers) Suspended tracks Arm rotation (full 360 degrees) Jib elevation Claw Additional motorized function (e.g. a winch). It will have 3 IR receivers, so there is room for one more function. The suspended tracks and oscillating axle will help the Halftracker tackle any fallen debris, and the claw arm will clear out any roadblocks for people to get through. Currently I have the tracks and their drivetrain and the front axle (the oscillating portion) completed. The tracks are pretty solid at this point, so building the chassis should be pretty straightforward. Photos:
The initial idea was to create a tank with the most helpful additions for post-apocalyptic, but then I realised that's not that mad max sooo; "Now the gun shoots spears instead of traditional tank rounds (this is also innkeeping with the ban on modifying parts), which are far easier to use independently of the industrial arms complex and fit the blades over guns aesthetic of mad max. There is a giant double wide dozer/shovel hybrid on the front both for creating fortifications and destroying them. On the back of the turret is a crane, while also being arguably the most important piece of machinery in construction it also allows for display of those you deem unworthy of a place in your convoy. The tanks itself is suspended on 5 sets of double wishbones pilfered from discarded medium duty trucks, while the general shape of modelled after tanks from throughout history on the whim of the history crazed lunatic that jerry-rigged the thing together when the world first fell apart." Back to the Lego; the supergun is the centrepiece and is one of the few shell ejecting guns built. The gun uses the newer spring shooters (roughly 1x4 brick sized) currently in a 6 shot magazine and will recoil the barrel, trigger the launcher, open the breach and the eject the round with one smooth motion. The gun barrel moves forward on the motor loading a round then suddenly reciprocates back on a spring performing all the other operations in a split second making it look like a real gun firing (I even made the shell cartwheel when ejected ;)). As everything is directly controlled by the barrel/recoil there is only need for one spring and as this spring does not have to contain the energy to launch the spear the spring can be relatively light allowing for multiple shots per second (the shells stream out like we all love). I will post picks and a vid once the gun is mounted in the turret, just had to make this post as I went from nothing to my best ever gun and tank chassis in less than a day.
I started out with a bit of a classical Mad Max-style build... A hot-rod, with an oversized engine, and high suspension... And nice pointy bits sticking out all over the place. It has since morphed into a hot-rod mated with monster truck, sprouting a crane from the middle, on Claas tires and requiring 12 shock absorbers... And its motorized! Photos will come tomorrow with the sun and the good lighting.
