Playing with Lego leads to ‘revolutionary’ design patents for Volvo CE

A soon-to-be-released Lego set is paving the way for real life heavy equipment for Volvo CE.

Lego Technic and Volvo CE construction toys joined creative forces with a team of children to design an autonomous construction machine.

The result of the partnership is Lego Technic’s Volvo Concept Wheel Loader Zeux set, which is scheduled for release in toy stores in August. The design also helped create a digital prototype for a real-world autonomous machine.

The partnership began as an informal team building event to inspire The Volvo CE and Lego Technic design teams in 2016, gradually evolved into an idea for an actual LegoTechnic product.

The goal was to design the construction machines of the future. Now, the collaboration has led to number of potentially revolutionary patents.

Arvid Rinaldo, brand communication and partnerships at Volvo CE, explained why it is relevant for their designers to work on futuristic construction machines with LEGO Technic.

volvo lego“We have enjoyed a truly fun and productive collaboration with the Lego Technic team over the past few years. It allowed us to test ideas for new types of construction machines for the future, both in terms of functionality, scale, design and interaction,” Rinaldo said.

“This model may seem futuristic now, but autonomous, connected and electric construction machines are already starting to be a reality. The Volvo Concept Wheel Loader Zeux is a realistic next step in the exciting evolution of our construction machines.”

Autonomous lawnmowers and vacuum cleaners are already a familiar sight in homes around the world and are generally considered safe to be around.

As the first self-driving cars were tested on roads, the gear wheels were turning in the heads of designers at Volvo CE in Sweden and the Lego Group in Denmark, as they worked to find new ways to increase safety and bring a more human aspect to the artificial intelligence in big construction machines.

A focus group consisting of children helped out in the process creating the Zeux. Looking at early drawings and models, the group gave feedback that led to the development of new, unique features. Two main features that the group decided on were a scout drone and the adjustable camera boom mounted on the roof of the vehicle, called the Eye.

In addition to the scout drones and built-in sensors a real-life model would have, the Eye illustrates a new and inventive feature: it will show exactly where the vehicle’s attention is directed, which means it can make eye contact with humans and acknowledge their presence.

lego volvo “When you cross a busy road, you watch out for dangers and try to make eye contact with drivers in your immediate vicinity. It’s an instinctive reaction that lets you evaluate your next move”, said Andrew Woodman, senior design manager for Lego Technic. “Should you stay where you are, or is it safe to move? It’s usually an easy assessment. With autonomous vehicles, you don’t have that interaction because you can’t see all the sensors that allow them to navigate around both stationary and moving objects.”

Woodman added it is not intuitive for humans to understand an autonomous vehicle’s next move or where it’s going

“While the Volvo Concept Wheel Loader Zeux will not be driving on roads, it would be interacting with workers at a construction site,” Woodman said. “So we set out to create features and functions that make the interaction between humans and machines as safe and intuitive as possible.”

AFC promise

One of the core Lego Technic design values is the “AFC promise,” which stands for “Authenticity, Functionality and Challenging building.” Models have to look as close to their real-life counterparts as possible, be fun to play with, and inspire builders to try new building techniques. So how does a futuristic model fit into especially the authenticity part of the promise?

Workshops in Billund, Denmark, video meetings and exchanges of concept sketches and sketch models allowed room to test wild ideas throughout the development process. As a result, you can see a lot of very interesting features like an extendable counterweight, raising and lowering chassis, 4-wheel steering and many other great ideas that fits all design values.

“Volvo CE and the Lego Group share the same values when it comes to our requirements for quality and usability, while at the same time pushing the boundaries of creativity and functionality,” Woodman said. “It has been very motivating helping Volvo CE to develop what could be the future of construction machines.”
