Have you ever watched a dragonfly? They can hover almost as if frozen in space wings beating so fast they appear as a blur, land with delicate precision on a waving blade of grass, skim gracefully over a pond and fly off at speeds that defy sight. Surely a target for biomimicry and that of course is what has happened. A helicopter used by sea rescue services based on dragonfly flight would be wonderful. Hmmm, scaling up insects is tricky. The fossil record indicates that the largest flying insects existed some 275 million years ago had wingspans of only around 700 mm (28 inches). So may be a dragonfly based rescue helicopter is conceptually inept. So in this case biomimicry has to stay in scale. In which case if you could mimic a dragonfly or aspects of a dragonfly what would you mimic. Given the aerial dexterity of the dragonfly it’s not surprising that Animal Dynamics, an Oxford University spin off, has developed Skeeter a tiny flapping winged drone specially designed for covert surveillance. Weighing no more than 30g, and designed to cost less and fly for longer than other hand-launched drones, it could, its creators claim, help reshape urban warfare. Biomimicry transforming urban warfare! It’s not difficult to see biomimicry playing out in armaments developments. Should this be discussed in D&T lessons? On the grounds of the subject reflecting activities in the world outside school it is difficult to say ‘No’. But any discussion will move into tricky territory very quickly. A surveillance drone, even a tiny one, can easily provide targeting information and missile flight path data for larger weaponised drones. And without too much difficulty be developed into a lethal weapon in its own right. Some argue that the basic technology itself is has no moral compass. The guidance technology used in missiles can just as easily be used for autonomous farm equipment. Where does this leave the designer? And where does it leave the design & technology teacher? As always comments welcome.
