The students were tasked with a rather open prompt. They should explore and design solutions for a context where autonomous construction machines collaborate with humans in a construction site. To make this collaboration effective and efficient, several factors relating to trust and communication should be incorporated.
The cx.Link is a concept to support autonomous construction vehicles operating alongside human workers on major construction sites. The system contains a command center, a pod with a beacon light on each construction machine, a wrist mounted display, and a hardhat. In concert they work to enhance communication and thus trust in construction sites. The vision is
Below follows some descriptions of the parts.
The command center is the brain and processing unity of the system. It receives a bird’s-eye view of the construction site from an overhead camera. This is combined with information about machine and worker positions. This information is communicated to the other parts of the system and is made available when needed. When needed it can, for instance, alert a worker of an imminent danger.
Each autonomous construction vehicle is fitted with a machine pod. The pod features a signal light, which communicates with workers on the construction site. Here, function and status of the machine is stated so that the user can see that it is operational.
Each worker will have some additional personal equipment, which will provide them with added capabilities for communication and increased safety. The wrist-mounted display is implemented on a smartphone with a wrist mount. It displays information for the worker. Additionally, it provides wireless connectivity and GPS positioning.
In all constructions sites, the hardhat is a mandatory personal equipment for all construction workers. In the cx.Link concept, the hardhat is fitted with additional functionality. It is fitted with a bone conduction headset and led lights for alerting the worker of danger, system functionality, and machine intent. Depending on the specific situation, the system will provide workers with relevant information to enable them to take appropriate action.
As a leader in the construction industry, Volvo Construction Equipment are exploring concepts for running fully autonomous construction machines in aiming to increase productivity and to enhance safety for people in the sites. Even in this scenario there will be people on the site, maintaining machines and leading the operations. Therefore, the aim of the project is to create a system that will enable efficient communication between human workers and automated machines. Such a system will increase safety and foster trust between the human workers and machines.

The framework is based on four dimensions of team innovation: Make, Observe, Visualize, and Engage.
We talk about dimensions rather than phases because innovation is not a linear process. Use elements of each dimension depending on your specific needs and objectives. Don’t forget to iterate and share your evolving ideas with others in your innovation network, which will help you move your big ideas forward.
The MOVE Workshop that is now available to MSPI and partners is based on a combination of findings from academic research at the US Defense Advanced Research Projects Agency (DARPA), Stanford University, Lund University (Andreas Larsson) and Blekinge Institute of Technology (Tobias Larsson), merged with the facilitators’ extensive hands-on workshop experience with a range of industry (e.g. aerospace, automotive, telecommunications), nonprofit, and government groups.
