Aussi mignon que la lampe Pixar et aussi agile qu&#x2019;un joueur de basket, ce nouveau robot a été [conçu](http://news.berkeley.edu/2016/12/06/wall-jumping-robot-is-most-vertically-agile-ever-built/) par des chercheurs de l&#x2019;université de Berkeley, en Californie, pour pratiquer l&#x2019;art du parkour. Une équipe chapeautée par Duncan Haldene a étudié les mouvements des galagos avant de mettre au point leur petit bébé de 25 cm de haut, appelé Salto &#x2014; diminutif pour « saltatorial locomotion on terrain obstacles ». Il bondit à une hauteur égale à trois fois la sienne et peut rebondit sur un mur comme un véritable athlète.

Si Salto n&#x2019;est pas le robot qui saute le plus haut, sa capacité à rebondit le distingue des autres. Dans une vidéo mise en ligne par l&#x2019;université de Berkeley, Haldene explique comment Salto pourrait être adapté pour des missions de sauvetage dans des zones difficiles d&#x2019;accès. Vous pouvez aussi y voir Salto en action.

Roboticists at UC Berkeley have designed a small robot that can leap into the air and then spring off a wall, or perform multiple vertical jumps in a row, resulting in the highest robotic vertical jumping agility ever recorded. The agility of the robot opens new pathways of locomotion that were not previously attainable. The researchers hope that one day this robot and other vertically agile robots can be used to jump around rubble in search and rescue missions.

Duncan Haldane, a robotics Ph.D. candidate at UC Berkeley, led the work. Haldane is a student in the Biomimetic Millisystems Lab of Ronald Fearing, a professor of electrical engineering and computer sciences.

To compare the vertical agility of robots and animals, the researchers developed a new metric to measure vertical agility, defined as the height that something can reach with a single jump in Earth gravity, multiplied by the frequency at which that jump can be made. Salto’s robotic vertical jumping agility is 1.75 meters per second, which is higher than the vertical jumping agility of a bullfrog (1.71 meters per second) but short of the vertical jumping agility of the galago (2.24). The robot with the second highest vertical agility that the team measured is called Minitaur (1.1 m/s).

“Developing a metric to easily measure vertical agility was key to Salto’s design because it allowed us to rank animals by their jumping agility and then identify a species for inspiration,” said Duncan Haldane, a robotics Ph.D. candidate at UC Berkeley, who led the work. Haldane is a student in the Biomimetic Millisystems Lab of Ronald Fearing, a professor of electrical engineering and computer sciences.

SALTO weighs 100 grams (3.5 ounces), is 26 centimeters (10.2 inches) tall when fully extended, and can jump up to one meter. Salto’s maximum jump height was roughly 1.008 meters (3.3 ft). For the wall jump, Salto attained an average height gain of approximately 1.21 meters (3.97 ft). Other robots can jump higher than Salto in a single leap. For example, TAUB, a locust-inspired jumping robot, can leap to 10.5 feet (3.2 meters) in a single jump.
