All-terrain, driverless Lego development automobile could possibly be our future


The Volvo Rottweiler is an autonomous development automobile that may work in tough terrain. It is outfitted with a 3D printer that create the supplies it makes use of to assemble buildings. And it is manufactured from Lego bricks.

Vida András, a 27-year-old Romanian architect, designed the Rottweiler for a contest run by Lego Technic and Volvo Building Gear. Entrants had been invited to think about the development machines of the longer term by figuring out tomorrow’s issues and making a machine that may sort out them. 

The Rottweiler took first prize out of 122 entries submitted from internationally. Lego most not too long ago teamed up with Volvo Building Gear for the Zeux, a self-driving idea wheel loader launched by Lego Technic in 2018.

The imposing Rottweiler measures 80x60x80 centimeters and takes 3,100 Lego bricks to construct. With its 4 legs and removable head, it appears to be like extra prefer it escaped from a sci-fi film than a constructing web site. That is no accident. The judges had been on the lookout for futuristic designs, and András wished to create one thing that evoked energy and performance.

“The energy of it and the usefulness of it appeals to me essentially the most,” he stated.

The Rottweiler and 9 different contest entries are at present on show at London’s Transport Museum.

Fixing tomorrow’s issues

Whereas different industries have embraced 3D printing, András says it hasn’t been used to its full potential but in development. 3D printing could possibly be used to experiment with new construction concepts and permit architects to design buildings utilizing shapes which can be “virtually inconceivable to type by hand.”

The 3D printer can also be key to the Rottweiler’s environment-conscious method. “3D printing is a means of lowering the manufacturing waste,” says András. He describes 3D printing as virtually wasteless from supply materials to ultimate product, including that it may assist cut back air pollution from factories.

Runner-up James Cox of London created the Volvo Icarus, a cellular photo voltaic plant with off-road capabilities. It is 100x60x40 centimeters and used about 4,000 Lego bricks. Cox says the title began out as a form of joke — “trigger clearly I did not fly too near the solar” — but it surely suited his idea and sounded cool. So he saved it.

Like András, Cox wished his entry to sort out the challenges posed by local weather change.

“As a result of the idea was to make a machine for the longer term, I believed if issues aren’t environmentally pleasant — if they don’t seem to be clear, if they don’t seem to be environmentally secure — they don’t seem to be going to work as a result of fossil fuels will run out. Environmental requirements are going to develop into stricter. We’d like a means round it, and it must be one thing that may work wherever.”

Cox conceived the Icarus as a solar energy generator. He then determined to make it cellular, including the off-road chassis after he’d constructed the mechanics for the photo voltaic array.

Volvo Rottweiler

The Volvo Rottweiler is a four-legged reply to tomorrow’s development challenges.

András and Cox took the mechanical design course of critically, each emphasizing the analysis concerned and the sensible facet of their work. Each began with a drawing, however then their approaches diverged.

András created the Rottweiler utilizing a digital constructing software. The design did not develop into a bodily actuality till he gained the competitors and Lego despatched him the items required to create it. In the meantime Cox labored freehand, constructing the Icarus with bodily blocks. When he submitted his entry, he included a video of the cellular energy plant in motion.

“Numerous entries are digital and so they do not truly exist and so they do not truly work,” Cox says. “So I made certain that it had a video so you might see each single half that was listed. You could possibly see it working.”

Impressing the judges

It takes so much to create a prize-winning Lego mannequin: You want the creativeness to sort out a design problem. You want the sensible information to convey your imaginative and prescient to life. And also you want the completed product to look superb.

However there isn’t any such factor as a “typical” Lego builder. Some entrants are skilled design engineers or graphic designers, however that is not all the time the case. One of many runner-up fashions is a service drone created by a 13-year-old.

This wasn’t the primary rodeo for both András or Cox. Each designers have gained and positioned in earlier Lego competitions and each have an thought of catch a decide’s eye.

András says he took on a giant problem with the Rottweiler. As a substitute of constructing a digger or a bulldozer, he used the Rottweiler’s removable heads to make it a multipurpose machine. The bold method paid off.

“The key to wow a Lego decide is attempt to not wow a Lego decide,” András stated. “One of the best factor you are able to do is … simply assemble what wows you. And when you’ve got 100% confidence in your development, I feel it’ll attain its objective and I feel it’ll wow everyone if it wows you.”

He additionally has an thought of how he may take the idea additional. He wish to add playability capabilities, maybe truly making it drivable, making the arm movable or utilizing a Lego Mindstorm pc to make it programmable.

In the meantime, Cox had some sensible recommendation for anybody who desires to get forward in a Lego competitors: Go large or go house.

“It is gotta look good. It is gotta look spectacular. And it is gotta… simply look large,” he says. Sure, you are able to do one thing intelligent with a small design, but when it would not look nice, it simply will not have the identical impression.

András was additionally pleased with his creation’s look, describing the Rottweiler’s animalistic look as one among his favourite options.

Judges from Lego and Volvo evaluated the entries based mostly on how effectively the fashions had been constructed, how futuristic their functionalities had been and the way thrilling they seemed. Arvid Rinaldo, who works in model communication and partnerships at Volvo Building Gear, highlighted the successful designs’ distinctive options and use of futuristic know-how.

“It is virtually like they arrive out of a science-fiction film,” he stated. “It is actually inspiring for our engineers to see … what folks from all around the world can do.”

The Rottweiler and Icarus ideas are actually on show on the London Transport Museum alongside eight extra futuristic Lego fashions. The Future:Construct exhibit is open via Could 16.
