All-terrain, driverless Lego construction vehicle could be our future
The Volvo Rottweiler is an autonomous construction vehicle that can work in rough terrain. It's equipped with a'3D printer'that creates the materials it uses to construct buildings. And it's made of Lego bricks.
Vida Andr's, a 27-year-old Romanian architect, designed the Rottweiler for a contest created by Lego Technic and Volvo Construction Equipment. The'contest'ran last fall on'Lego Ideas, a site where fans enter competitions and submit their own designs in the hopes they'll be popular enough to be made commercially. Entrants were invited to imagine the construction machines of the future by identifying tomorrow's problems and creating a machine that will tackle them.'
The Rottweiler took first prize out of 122 entries submitted from across the world.'Lego'most recently teamed up with'Volvo'Construction Equipment for the'Zeux, a self-driving concept wheel loader released by Lego Technic in 2018.
The imposing Rottweiler measures 32x24x32 inches (80x60x80 centimeters) and took 3,100 Lego bricks to build. With its four legs and detachable head, it looks more like it escaped from a sci-fi movie than a building site. That's no accident. The judges were looking for futuristic designs, and Andr's wanted to create something that evoked power and functionality.
"The strength of it and the usefulness of it appeals to me the most," he said.
The Rottweiler and nine other contest entries are'on display this week at the London Transport Museum.Solving tomorrow's problems
While other industries have embraced 3D printing, Andr's says it hasn't been used to its full potential yet in construction. 3D printing could be used to'experiment with new structure ideas'and allow architects to design buildings using shapes that are "almost impossible to form by hand."
The 3D printer is also key to the Rottweiler's environment-conscious approach. "3D printing is a way of reducing the manufacturing waste," says Andr's. He describes 3D printing as almost wasteless from source material to final product, adding that it could help reduce pollution from factories.
Runner-up James Cox of London created the Volvo Icarus, a mobile solar plant with off-road capabilities. It's 39x24x16 inches (100x60x40 centimeters) and used about 4,000 Lego bricks. Cox says the name started out as a sort of joke -- "cause obviously I didn't fly too close to the sun" -- but it suited his concept and sounded cool. So he kept it.
Like Andr's, Cox wanted his entry to tackle the challenges posed by climate change.
"Because the concept was to make a machine for the future, I thought if things aren't environmentally friendly -- if they're not clean, if they're not environmentally safe -- they're not going to work because fossil fuels will run out. Environmental standards are going to become stricter. We need a way around it, and it needs to be something that can work anywhere."
Cox conceived the Icarus as a solar power generator. He then decided to make it mobile, adding the off-road chassis after he'd built the mechanics for the solar array.
Andr's and Cox took the mechanical design process seriously, both emphasizing the research involved and the practical side of their work. Both started with a drawing, but then their approaches diverged.
Andr's created the Rottweiler using a digital building tool. The design didn't become a physical reality until he won the competition and Lego sent him the pieces required to create it. Meanwhile Cox worked freehand, building the Icarus with physical blocks. When he submitted his entry, he included a video of the mobile power plant in action.
"A lot of entries are digital and they don't actually exist and they don't actually work," Cox says. "So I made sure that it had a video so you could see every single part that was listed. You could see it working."
Impressing the judges
It takes a lot to create a prize-winning Lego model: You need the imagination to tackle a design challenge. You need the practical knowledge to bring your vision to life. And you need the finished product to look amazing.
But there's no such thing as a "typical" Lego builder. Some entrants are professional design engineers or graphic designers, but that's not always the case. One of the runner-up models is a carrier drone created by a 13-year-old.
This wasn't the first rodeo for either Andr's or Cox. Both designers have won and placed in previous Lego competitions and both have an idea of how to catch a judge's eye.
