Five years ago, French aeronautical engineer Edwin Van Ruymbeke successfully crowdfunded his Bionic Bird – it’s a remote-control model that flies by flapping its wings, just like a real bird. Now he’s back, with the insect-inspired MetaFly.
Reminiscent of the bioinspired robots made by Festo, the MetaFly weighs less than 10 grams (0.35 oz), is 19 cm long (7.5 in), and has a 29-cm (11.4-in) wingspan. The wing-flapping is handled by a mechanical coreless motor (with an aluminum heat sink), which is in turn powered by a rechargeable lithium-polymer battery.
That battery is charged by docking the MetaFly with the included 2-channel radio remote control unit, drawing current from that device’s four AA batteries. One 15-minute charge should be good for eight minutes of flight time, with 15 flights possible on one set of the remote’s batteries. Users can also opt for a separate 1,500-mAh power bank, which reportedly manages 20 12-minute charges before needing a recharge of its own.
