Imagine if there have been a robotic fish that filtered microplastic particles out of the water because it swam. Well, now there is one, and it is the bodily model of the profitable idea within the first-ever Natural Robotics Contest.
Announced this May, the University of Surrey’s Natural Robots Contest invited members of the general public to submit their concepts for animal- or plant-inspired robots able to performing actions that may assist the world.
Plans referred to as for panelists from varied British and European analysis institutes to pick what they thought was the most effective idea, which might subsequently be made right into a useful prototype. Engineers would proceed to additional develop the expertise, plus laypeople would additionally have the option to take action by accessing the open-source plans for the machine.
The profitable entry turned out to be the plastic-collecting Robo-fish, designed by chemistry undergrad Eleanor Mackintosh – who’s coincidentally a University of Surrey pupil.

The robotic swims by flapping its tail, holding its mouth broad open to gather water (and microplastics) in an inside cavity because it does so. Once that cavity is full, the bot closes its mouth, opens its louvre-like gill flaps, and pushes the water out by means of these flaps by elevating the ground of the cavity. A nice mesh connected to the gill flaps permits the water to go by means of, however captures the plastic particles.
In its present bodily type, the 50-cm (19.7-in)-long Robo-fish collects particles as small as 2 millimeters. It additionally sports activities onboard sensors to observe turbidity and underwater gentle ranges, plus it makes use of an IMU (inertial measurement unit) to trace its actions throughout the water. Oh sure, and it glows at midnight.
That stated, future incarnations might conceivably seize a lot smaller particles. Other potential enhancements embrace a quicker, extra hydrodynamic physique form, a extra highly effective tail, and the flexibility to swim autonomously – the present prototype works by hard-wired distant management.

“Water air pollution, particularly plastic air pollution, is a large drawback. It’s not simply the ocean which suffers however rivers, streams, lakes and ponds. This makes it an issue with no one-size-fits-all answer,” Mackintosh instructed us. “My design was centered on having a versatility in its perform. What higher creature to deal with the problems in water our bodies than one which lives in them? Fish are tailored to their atmosphere, and gills are an unimaginable mechanism in nature which are specialised to filter oxygen into the bloodstream – so I tailored my design from that, with the aim of making a filter for microplastics as a substitute.”
