Untethered robots miniaturized to the length scale of millimeter and below attract growing
attention for the prospect of transforming many aspects of health care and bioengineering …

Nanotechnology has stimulated revolutionary advances in many scientific and industrial
fields, particularly in energetic materials. Powder mixing is the simplest and most traditional …

Heavier-than-air flight at any scale is energetically expensive. This is greatly exacerbated at
small scales and has so far presented an insurmountable obstacle for untethered flight in …

For centuries, scientists have explored the limits of biological jump height,, and for decades,
engineers have designed jumping machines,,,,,,,,,,,,,,–that often mimicked or took inspiration …

Mobility and robustness are two important features for practical applications of robots. Soft
robots made of polymeric materials have the potential to achieve both attributes …

Insects perform feats of strength and endurance that belie their small stature. Insect-scale
robots—although subject to the same scaling laws—demonstrate reduced performance …

Autonomous robots—systems where mechanical actuators are guided through a series of
states by information processing units to perform a predesigned function—are expected to …

INTRODUCTION Mechanical power, whether for launched missiles or running humans, is
limited by the universal, physical trade-off between force and velocity. However, many …

Fleas can jump more than 200 times their body length. They do so by employing a unique
catapult mechanism: storing a large amount of elastic energy and releasing it quickly by …

The jumping motion is adapted by Earth's creatures to achieve rapid maneuverability and
energy-efficient hurdling over uneven terrains or large obstacles. Herein, the continuous …
