Last week, our CTO, David de Haaij, visited DSEI UK 2025 with a clear mission: to exchange ideas, build global networks and stay sharp on the evolving needs of the defence sector. And as expected, DSEI delivered.
With halls packed full of the world’s most advanced defence technologies, satellite systems, autonomous drones, battlefield communications platforms, and cutting-edge tactical gear, the event provided an incredible look at where defence and aerospace are headed.
But amidst all the innovation, one pair of machines seemed to steal the show:
The robot dogs.
Boston Dynamics’ Spot and Unitree’s Go2 were not just popular attractions. They were live examples of how robotics, artificial intelligence and RF communications are converging to redefine mobility, security and situational awareness in real-world defence environments.
When the “Cool Factor” Meets Real-World Utility
It was hard to miss the buzz surrounding these agile quadrupeds. People stopped to take photos, shoot videos and watch their movements in action. Even seasoned engineers and tech experts like David couldn’t help but be drawn in. After all, seeing a robot dog in action – climbing stairs, navigating crowds, or carrying payloads – is more than just a gimmick. It’s a glimpse into the future.
In a field like defence where reliability, mobility and adaptability are everything, machines like Spot and Go2 are not just cool tech – they are tactical assets. Designed for real-time reconnaissance, remote inspection, perimeter security and even hazardous environment exploration, these robots are changing the way we approach complex missions.
Let’s Talk Tech: What Makes These Robots Tick?
Both Spot and Unitree Go2 are marvels of engineering. Their movement systems mimic real animal biomechanics, with each leg controlled by multiple actuators that allow for stable, responsive navigation across a variety of terrains.
But what really powers their performance in the field is not just what you can see on the outside.
It’s the RF technology and wireless communication systems inside that make these machines truly autonomous.
- Real-time wireless control: Both robots are equipped with advanced Wi-Fi and low-latency radio systems for live remote control and data feedback.
- Sensor integration: From LiDAR to stereo vision, their ability to perceive the environment depends on robust, low-noise signal transmission – often routed through custom coaxial cable assemblies.
- Edge computing: RF modules communicate directly with onboard processors to navigate, relay video, and coordinate with other systems or command centres.
- Antenna performance: Whether it’s for receiving GPS signals or transmitting secure video feeds, the antenna systems are critical for maintaining consistent and high-integrity comms links.
Without reliable antennas, robust coaxial cabling, and precision RF tuning, these machines would lose their edge in the environments they are built to perform in.
Why RFShop is Watching Closely
At RFShop, we do more than admire technology like this. We build the kind of connectivity infrastructure it depends on. That includes:
- High-quality custom coaxial cables that can handle vibration, temperature extremes and interference.
- Precision-engineered antenna systems for multi-band communication across 4G, 5G, Wi-Fi, GPS and private networks.
- Rapid prototyping and local manufacturing for project-specific RF components.
- Expert RF simulation and design via Black Art Technologies to ensure every element is engineered for performance.
Whether it is a robot dog patrolling a base, a remote sensor network in a mining operation or a data system onboard a lunar lander, the one constant is RF connectivity.
A Shared Future Across Industries
What makes the rise of these robotic systems so exciting is not just their defence applications. The same RF requirements and design principles apply to:
- IoT platforms in industrial automation
- Autonomous vehicles navigating remote terrain
- Mining and exploration systems in harsh, GPS-denied environments
- Space communication systems where size, weight and efficiency are critical
Every application demands custom antennas and cable assemblies that deliver uncompromising reliability. That’s exactly where we come in.
Final Thoughts from DSEI
David returned from DSEI with more than just brochures and business cards. He brought back a deeper appreciation for how fast the landscape is shifting – and how critical RF communication systems are in shaping the next generation of defence and aerospace capabilities.
Spot and Go2 may have stolen the spotlight, but behind the scenes, it’s the invisible links – the cables, connectors and antennas – that make it all work.
If you are building the future of mobility, security, or automation, and you need RF systems that are just as advanced as your platform, we are ready to work with you.
Let’s design what’s next, together.
