An Engineer in Wonderland – Hopping robot
For military use, and intended to be finished this year, the Precision Urban Hopper can jump over or on to as many as 30 obstacles that are 40-60 times its own height.
“Hopping mobility has been shown to be five times more efficient than hovering when traversing obstacles at heights under 10 meters, which allows longer station-keeping time for the same amount of fuel,” said Sandia.
“Researchers addressed several technical challenges, including appropriate management of shock forces during landing, controlling hop height from varying terrain including concrete, asphalt, sand and vegetation and controlling landings to limit tumbling.”

Technically fascinating but, if one was chasing you, potentially terrifying.
