Volvo CE and LEGO® Technic introduce ZEUX

Volvo Construction Equipment and LEGO® Technic team up with children to create an autonomous concept wheel loader of the future.

Volvo Concept Wheel Loader ZEUX is a revolutionary autonomous concept wheel loader. Jointly developed by Volvo Construction Equipment and Lego® Technic.

What started out as a fun, informal team building event to inspire the Volvo CE and LEGO® Technic design teams in 2016, gradually evolved into a fully fledged autonomous concept wheel loader. Their goal: Design the construction machines of the future.

The collaboration made it possible to test ideas for new types of construction machines, both in terms of functionality, scale, design and interaction and to bring a more human aspect to the artificial intelligence in big construction machines. The Volvo Concept Wheel Loader ZEUX is a realistic next step in the exciting evolution of our construction machines. A focus group consisting of children helped out in the process of 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 the mapping drone and the adjustable camera boom mounted on the top of the vehicle, called “the Eye”.

THE EYE

The Eye illustrates a new and innovating 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. This is something that does not come natural with autonomous vehicles, because a human normally can’t see all the sensors that allow an autonomous vehicle to navigate around both stationary and moving objects. The Eye solves this problem, making the interaction between humans and machines as safe and intuitive as possible.

THE DRONE

The drone hovers above the ZEUX wheel loader, making it even more aware of its surroundings, making it possible for the ZEUX to become aware of things that are out of its immediate line of sight and plan the work.

THE MOTORS

Since ZEUX does not have an operator in a cab it can perform movements of the chassis that would not be possible otherwise. The frame is what we call a scissor frame that can be lowered or raised as needed. In this way it can balance and gain the optimal position and angle for the task at hand. Balance is kept by automatic movement of the counterweight (which doubles as the battery pack). This means the ZEUX can alter its center of gravity as needed. On site this means that ZEUX can reach much higher than a conventional machine, which becomes useful while tipping. When filling the bucket the whole machine can lower itself, and when lifting back up the machine gets the lifting energy for free by automatically rebalancing the counterweight.

AUTONOMOUS MACHINE

Since ZEUX does not have an operator in a cab it can perform movements of the chassis that would not be possible otherwise. The frame is what we call a scissor frame that can be lowered or raised as needed. In this way it can balance and gain the optimal position and angle for the task at hand.

When filling the bucket the whole machine can lower itself, and when lifting back up the machine gets the lifting energy for free by automatically rebalancing the counterweight.

FULLY ELECTRIC

The ZEUX autonomous wheel loader is fully electric and its 150 kWh battery allows it to operate for between three to five hours before it will return to its charging station to charge its batteries by induction charging. This eliminates the need for it to be plugged in in order for it to recharge. This allows the ZEUX to operate more or less continuously.
