Small robots might get extra elevate after they hover by shifting their wings in a “treading water” movement as a substitute of flapping them like hovering bugs do.

In an experiment with a robotic wing, Swathi Krishna on the College of Southampton within the UK and Karen Mulleners on the Swiss Federal Institute of Know-how in Lausanne, discovered that flying micro-robots might hover as much as 50 per cent extra effectively in the event that they used a wing …
