Oxford uses water waves to steer a robot around obstacles
On September 15, the University of Oxford described a water-wave computing experiment that guided a robotic vehicle around obstacles. The research was published in Nature Communications.
Actuators turn information about the surroundings into waves in a container. A camera reads the resulting patterns, which guide the vehicle. The physical behavior of the water becomes part of the computation.
The team also simulated the approach using tiny waves in magnetic material as a route toward compact chips. It has not announced a finished processor for household robots.
Our analysis
Intelligence need not all live in a central brain
Calling this merely an unusual computer misses its broader appeal. What interests us is that the natural behavior of water does part of the computation. Instead of reproducing every process in software, the system delegates some processing to the physical material itself.
If this approach develops further, a robot’s capabilities might depend less exclusively on its central AI. A soft hand or contact with the floor could also help shape its responses. Companies skilled in materials and physical design could enter the competition to build intelligent machines from a different direction.
How could everyday life change?
The following is a possible future based on this news.
A home where small robots make decisions on the spot
If the approach can be made compact and efficient, robots could decide how to move locally instead of sending every observation to a distant server. A small machine might avoid toys and stop beside a dropped object even where home Wi-Fi is weak. Everyday movements could become easier to delegate to small devices.
Further ahead, homes might use several specialized machines for floors, plants and carrying objects, instead of relying solely on one expensive general-purpose robot. The possibility worth watching is smaller hardware for local decisions, not robots carrying bowls of water.
