Basilisk lizard is also known as “Jesus Christ Lizard” because it can run on water. Developed by a team at Ben Gurion University in Israel, amphistar, inspired by serpentine lizards, is the latest member of the school’s star robot family. < / P > < p > the original Fstar (flying sprawl tuned autonomous robot) robot is characterized by an adjustable angle of spread arm, one side is a wheel, the other side is a propeller. This allows it to roll along the ground like a car or fly like a quad. < / P > < p > the subsequent rstar (rising sprawl tuned autonomous robot) robot retained the round wheel on one side, but replaced the propeller with a non spoke wheel on the other side. It uses round wheels to move on flat terrain, but actually turns itself over and uses spoke wheels to drive on rough ground. < / P > < p > < p > “palm size” amphistar retains outrigger deployable arms and now has a total of four propellers – two at the bottom of each arm. When moving on a surface such as grass or gravel, the angle of the arm makes the propeller blades function like the rimless spokes of rstar, digging and pulling the robot forward. This configuration allows it to crawl at a top speed of 3.6 meters per second. < / P > < p > after reaching the water, it continues to use the propeller, and now the angle of the propeller allows it to “run on the water” at a maximum speed of 1.5 m / s. In other words, it can also move across the water in a slower, more boat like manner, keeping it buoyant with a pair of buoyancy tanks. Future plans include the ability to swim underwater. < / P > < p > “we envision amphistar for agricultural, search and rescue and mining applications where both crawling and swimming are required,” said Dr. David Zarrouk, director of the University’s bioinspired and Medical Robotics Laboratory.
