“This Robot Thinks Like a Brain”: New Navigation System Slashes Power Use by 90% and Keeps It Running for Days

The latest advancements in robotics are bringing us closer to a future where machines can navigate the world with the efficiency and energy conservation akin to the human brain. Researchers at the QUT Centre for Robotics have unveiled a groundbreaking navigation system known as Locational Encoding with Neuromorphic Systems (LENS). This innovative system promises to revolutionize how autonomous robots operate by drastically reducing energy consumption. By mimicking the brain’s efficiency, LENS uses less than 10% of the energy required by conventional systems, paving the way for robots that can operate longer and explore further without the need for frequent recharging.

Understanding Neuromorphic Computing

Neuromorphic computing is a game-changer for robotics, especially in energy-intensive applications such as search and rescue missions, deep-sea exploration, and space travel. Traditional navigation systems consume significant amounts of power, which limits the operational range and duration of robots. Neuromorphic computing, however, addresses this issue by cutting down the energy needs for visual localization by up to 99%. This advancement is critical for extending the operational capabilities of robots. Dr. Adam Hines, a leading neuroscientist, emphasizes the potential of neuromorphic systems, which, although known for their efficiency, have been challenging to deploy in practical applications until now. LENS demonstrates this potential by accurately recognizing locations along a nearly 5-mile route with a storage footprint almost 300 times smaller than current systems.

The Combination of Advanced Technologies

The remarkable efficiency achieved by LENS is the result of a sophisticated combination of technologies. At the core of this system is an event camera, a specialized device that continuously detects changes and movement in the environment at a microsecond level, rather than capturing static images. This approach closely mimics how human vision processes changes, making it a crucial component of visual place recognition. This “movement-focused” data is processed by a brain-like spiking neural network on a low-power chip, all housed within a compact system. As Dr. Tobias Fischer explains, the event camera and spiking neural network work in tandem to provide an energy-efficient solution that meets the performance and endurance requirements for practical robotic applications.

Implications for Future Robotics Applications

The potential applications of the LENS system are vast and varied. By equipping robots with this advanced navigation technology, we could see significant improvements in disaster recovery operations, planetary exploration, and marine monitoring. These robots would have the capability to map disaster sites extensively, explore other planets for longer periods, and monitor marine environments with unprecedented endurance. The development of neuromorphic systems is accelerating rapidly, with companies like Intel leading the charge by launching large-scale neuromorphic computer systems like Hala Point. These advancements aim to make artificial intelligence more sustainable, processing information faster and more efficiently than ever before.
