Their findings were published earlier this month in the peer-reviewed journal Bioinspiration and Biomimetics in an article entitled "A novel wave-like crawling robot has excellent swimming capabilities."
The robot has potential applications in search and rescue, especially during natural disasters such as floods and tsunamis. It also has potential applications in marine agriculture and fish feeding as the robot attracts fish instead of repelling them.
Whether on land or in the water, the robot moves quite quickly. On land, the robot crawled at 1.5 body lengths per second (B/s) and swam at 0.74 B/s. It can be outfitted with legs or wheels at the front which increases its crawl speed, especially over uneven terrain.
"The single motor and bioinspired design contribute significantly to the robot's efficiency and the relative simplicity of its design means it is scalable to any size," explains Dr. Zarrouk.
His research goal is to produce robots that can complete complex maneuvers yet use very little power to run and are straightforward to produce.
In addition to Dr. Zarrouk and Omer Guetta, Dan Shachaf, and Rotem Katz also contributed to the project.
The study was supported in part by the Pearlstone center for aeronautical studies and by the Helmsley Charitable Trust through the Agricultural, Biological and Cognitive Robotics Initiative, and by the Marcus Endowment Fund, both at Ben-Gurion University of the Negev, and by the Israel Science Foundation, Grant No. 1279/18 and the Ministry of Science and Technology, Grant No. 3-16645.
