A robot fitout with real pigeon feathers flies like a real pigeon.
A robot fitout with real pigeon feathers.
A Robot resemblance with pigeon feathers may Point to the future of aerospace engineering a continuously morphing wings.
David Lentink and his colleagues at stanford university in california first looked at joints and how they control the spread of their wings.They develop pigeonbot using a set of biohybrid morphing wings with 40 underactuated pigeon feathers ,20 on upper side and 20 on lower side.
Lentink says: ' We attached a marker onto each individual wing and we were able to carefully measure the relationship between feather motion and bone ,we then just moved the wing,in and out.'
WORKING:
Birds can modify the shape of their wings by fanning out their feathers or shuffling them closer.those adjustments allow birds to cut through the sky more nimbly then rigid drones. Angles of two wings joint the wrist and the finger most affect the alignment ,the bird used its 'wrist' when wings was partly retracted and 'finger' when extended to control flight this movement allow the feathers to be in constant state of interaction allowing the birds wings to morph continuously mid-flight.
This reduces the number of variables_or degrees of freedom_required to model the wings.
LENTINK; "We let go of the idea that you have to control every degree of freedom and i think future aircraft will benefit from this finding.Future aircraft may not flap their wings ,but i think they change shape." Pigeon bot ,it is powered by a propeller and has wrist and feather joints in each wing that can be controlled remotely .its average speed is about 40 kilometers per hours which is a bit slower then average pigeon. Flight was only possible because certain molecules embedded throughout the feathers.these molecules which are just 10 micrometers across, allow feathers to move away from each other while ensuring they don't get too far apart .this in turn reduces the level of individual feather control required for accurate flight.
The Researches believe that the Divectional Velcro discovery is one of the more important finding from their study, surprisingly they are not pursuing any additional applications amd have decided not to patent the finding. So,that their discovery can benefit society at large.
