In what is becoming a little bit of a theme, I submitted another design for a Lego contest. In the long line of Eurobricks.com contests, the Technic Challenge 10 called for a pneumatic build. Challenge accepted!
The contest had very few constraints other than the build had to use Pneumatics. As I have mentioned before, working with pneumatics is not my preference. I don’t like them, so it was good for me to step out of my comfort zone.
I was feeling especially creative this time, so I thought about a number of concept ideas. Pneumatics do not tend to work smoothly when lifting arms so I decided against an excavator and a loader early. Additionally, I was not willing to invest in additional parts for this project. After a couple of drafts, the idea of this bulldozer was born. Taking some inspiration from some of John Pope’s design, the basic idea was there. The dozer would have different tracks, a three movement blade, a crazy engine, and a forward thinking design.
I started with the tracks. After moving the axle points four wheels countless times, I came up with a design I liked. I made another one, and linked them together. The I worked on the blade. The dozer would have a lift, tilt, and side to side angle adjustment. After playing around with some idea, I found a solution I liked. Two pneumatic rams were on the front to lift the blade on the top. Then two links were connected low on the two sides of the blade, and then on each side of the dozer. These points on the dozer were moved fore and aft by on pneumatic ram each. These side rams would move the blade left or right individually, or together they would tilt the blade up or down. Additionally, it allowed all the tubing to be internal.
I added a small compressor powered by a Power Functions M motor, and the battery box under the cab, and added the 16 cylinder engine (coupled V-8 and Flat 8). The cab was easy to get the shape I wanted, and gave me some space for another pneumatic ram to open the hood. I then decided to add a ripper since I had one pnuematic left. The new 1×11 ram a great addition, but a little more power could have been used for the ripper.
I was pleased with the look the bulldozer. The functions worked well, but on reflection, the were not exciting enough to be competitive for a contest. After two pneumatic builds in a row, I find some of the frustrations I have with them remain, but I am discovering some charms as well. We’ll see what comes next.
I enjoy participating in LEGO contests, but I cannot join all of them. Sometimes the timing, my build interest, and the available parts all line up in a way that I can submit an entry. I was able to submit something for the LEGO Technic Mercedes-Benz Future Truck Competition hosted at Rebrick.com because everything fell into place. I hope you enjoy the submission.

While I would love to see us progress to flying and fully autonomous vehicles, a complete technological and transportational paradigm shift needs more than 30 years; see where we were in 1985. I envision transportation in 2045 will be affected by a couple of features:
Cities will be more dense
Active transportation will occupy a greater share of road users
Electric charging options will be more available and more diverse
Vehicles will still have drivers, but the drivers will be heavily assisted with technology
Fossil fuels will still be used, but significantly reduced and not limited solely to petroleum
Cargo will not change, but storage will
Various loads to apply to the Athane via the SmartStack System.
With this is mind the 2045 Mercedes-Benz Athane has been designed to best fit within this context. While taking this context into account, the Athane prioritizes three values as most important: Safety, Sustainability, and Versatility.

Here is the Press Release-
May 22, 2045, for immediate release
The 2045 Mercedes Benz Athane prioritizes safety, sustainability, and versatility. The 2045 Athane is the most advanced and cost effective truck in our 150 years of truck building experience.
As cities become denser and multiple transportation modes are becoming more prevalent, road safety for all road users must be paramount. The Athane’s ThemoCommLink (TCL), located on the right front and right rear bumpers, allow motorized vehicles to communicate to one another. The TCL also detects the heat signature of pedestrians and cyclists. Identification and communication with other users, keeps all road users safer. The driver is seated in the center and forward in the cab to increase vision. Retention of a human driver allows for relational interaction at the job site, and helps the technology make good decisions about varying road situations. The TCL Technology assists the driver so fewer errors are made. The front bumper shaping and full length wheel guards lowers the severity of crashes with non-motorized users should they occur. The Athane uses eight steerable wheels to improve weight distribution and increase city maneuverability. While many manufactures are switching to floatation and hover type drivetrains, this setup allows for unmatched braking control, and removes disruptive air currents to those walking and cycling close to the moving truck.
The Athane’s Methane-Hybrid driveline continues Mercedes Benz’s prioritization of decreasing fossil fuel use. The Athane uses electric propulsion using energy stored in the batteries under the cab and bed. Battery charging is done by braking and by a small methane powered combustion engine behind the cab. Additionally, the Athane can be ordered with an induction charger under the cab to work with newly developed induction charging roadways being installed in many municipalities. Methane gas is clean burning, and a significant byproduct of the waste and recycling process currently in place with Octan Rubbish. A partnership with Octan Energy and Mercedes Benz has developed a standard way to reap, store, transport, and fuel the Athane’s regeneration engine using methane gas. Removable methane tanks are house behind the rear wheels, and in smaller tanks in the cab.
Today’s logistics companies are searching for ways to improve versatility and lower cost. The Athane’s SmartStack systems allows for interchangeable bodies, cargos, and applications all with one common truck. The SmartStack system makes it easy to change the load in just minutes. The connection fits the international container standard. Many body work designers are applying this standard as well. In one afternoon, you can ship a container, deliver a load of concrete, and pull a fifth-wheel with the standard hitch.
Welcome to the future. The 2045 Mercedes Benz Athane keeps all road users safer, decreases our harm on the planet, and supports all work tasks needed.
