(December 22, 2015) In recent years, advanced robotic
platforms have provided assistance to crisis intervention teams in the wake of
man-made and natural disasters. The objective of such robots, in various sizes
and shapes, has been to intervene where humans cannot and send life-saving data
to rescue teams in the field.
Now, a miniature robot is poised to make a major
contribution to the field of advanced robotics. The new locust-inspired robot,
developed in Israel by researchers from Tel Aviv University and Ort Braude
College, is five inches long and weighs less than one ounce. It can jump 11
feet high — more than twice the height of similar-sized robots, according to
the researchers — and cover a horizontal distance of 4.5 feet in one leap. The
researchers believe the robot will perform well in search-and-rescue missions
and in reconnaissance operations in rough terrain.
Inspired by nature
“Our locust-inspired, miniature jumping robot is a beautiful
example of bio-inspired technological innovation,” TAU’s Prof. Amir Ayali, who
led the research, said in a statement. “Miniature robots are of special
interest in the robotics field, attracting a lot of attention and research. The
manufacture of tiny robots is cheap and efficient; their small size allows them
to traverse difficult and unknown terrain; and many can be used in any given
situation.”

The scientists printed out the body of the robot on a 3D
printer using plastic materials that can also be found in Lego blocks. The
robot’s legs were composed of stiff carbon rods, and its torsion was made of
springs of steel wire. A small, on-board battery powers the robot, which is
remotely controlled.
“Biological knowledge gained by observing and studying
locust, was combined with state-of-the-art engineering and cutting-edge
technologies, allowing biological principles to be implemented in a miniature robotic
jumping mechanism,” according to Ayali.
