What is the Battlefield of Things 2: Drones Hackathon?
The Battlefield of Things 2: Drones is a two-and-a-half-day innovation event that will bring Belgium Defence personnel together with industry experts, drone enthusiasts, researchers, and students.
Together, participants will push the boundaries of UAS technology. They will also look at the business side of growing the drone ecosystem in Belgium.
For both experienced professionals and passionate newcomers, this event is a unique opportunity to work on drone hardware and software, to tackle real-world challenges proposed by Belgian Defence, to build network across the drone ecosystem, and shape the future of drone technology.
Challenges
The Battlefield of Things 2: Drones hackathon revolves around three key challenges: Technology Innovation, Ecosystem Innovation, and Procurement Innovation. Each challenge includes specific problems identified through workshops with Belgian Defence and industry experts, ensuring real-world impact.
Success will require expertise, creativity, and strategic thinking.
Technology challenges
We are looking beyond the obvious, easy solutions for all three technology challenges. We need better ideas to get an edge. So, get ready to do some seriously blue-sky thinking.
An ideal pitch for one of the Technology challenges would include a functioning prototype. But, if it’s impossible to build a meaningful prototype for your wild idea during the event, that’s fine – build a simulation that proves your point, show a model, or even draw a sketch!
How might we develop low-cost drones (additional hardware cost of maximum EUR 300 per drone) that can carry out such sophisticated tasks?
Think upgraded sensors, swarming, map reading, dynamically identifying gaps in jamming – and of course any other insane ideas you might come up with.
How might we design and deploy low-cost, fully autonomous anti-drone drones that could be deployed by a single operator?
Imagine designating a target for the drone and launching it within a few seconds, with minimal use of connectivity or additional hardware.
Bonus question: thinking a little bit ahead, how might we make the deployment and targeting of anti-drone drones completely automated?
How might we enable operators to control multiple drones at the same time, doing substantially more with the same small team?
Think better human/machine interface (example: https://www.primordial-labs.com/) and AI; all other ideas are welcome!
Ecosystem Challenges
Some challenges are simply too big for any one company to tackle. But if we can pool resources of an entire ecosystem, we can move mountains.
How might we recruit and maintain a cadre of up to 1000 trained drone operators?
Think about new ways of popularising the hobby of drone flying. Further, keep in mind current bottlenecks such as expensive equipment, shortage of dedicated air space, limited supply of drones for hands-on training, and constraints of currently available drone simulators.
How (and by whom) would it be managed? Financed?
How would it keep being a useful tool for the entire ecosystem instead of slowly turning into yet another ineffectual industry “body” that only serves its own perpetuation? Show us your (business) plan.
Procurement Challenges
Belgian Defence would like to ensure national autonomy in drone production. While some drone manufacturing capabilities exist in Belgium, they are currently not adapted to delivering the necessary supply even in peacetime, and certainly not to scaling up to wartime requirements.
While BELDEF is prepared to contribute to development of such an ecosystem through R&D funding, such funding can only be added to a solid base.
How would the Belgian drone ecosystem (combining private sector, academia, and Defence) need to be organised to become a competitive European actor for large-scale manufacturing contracts?
Think about – for example – pooling resources to substantially increase shared business development activity in the civilian and military space, and don’t forget other aspects (such as R&D, collective procurement, etc.) that might need to be coordinated. Recommended reading here.
How might the Belgian drone ecosystem – formalised only to a limited degree – define an inexpensive drone system (hardware, sensors, firmware, controller, software) in line with Modular Open Systems Architecture (MOSA) approach, and keep it up to date?
A successful project might include:
- A description of MOSA combining a sub-EUR 2 000 FPV attack system, a sub-EUR 10 000 ISR quadcopter system, and a sub-EUR 50 000 long-range attack system, including command and control, data management and the actual flying platforms.
- An overview of the process for creating the initial MOSA and ongoing review and improvement.
Note that while BELDEF will be giving input and feedback, as well as providing relevant technical knowledge, it will not be in the driving seat of creating MOSA.
Recommended reading here.
How might the Belgian drone ecosystem create and continuously evolve a shared technology roadmap in consultation with BELDEF?
A successful project might include:
- An example of a technology roadmap for drones with a 5-year horizon
- The process for coordination of R&D efforts with universities to ensure timely integration of fundamental research
- Infrastructure requirements for testing facilities
- Needs for knowledge sharing from Belgian Defence
Winning criteria
The Jury will evaluate all projects on these five criteria:
- Desirability (Does the solution directly address the problem and align with the scope of the relevant challenge? Does it offer a tangible difference?)?
- Viability (is there sound business logic behind the solution?)
- Feasibility (from a technical perspective, is it easy to implement? Does it rely on existing technology, or does it require significant development?)
- Creativity (novelty of approach)
- Elegance of the solution (simple yet effective)
