The search and rescue robot can change its shape and center of gravity to go anywhere

A new robot designed to manage search and rescue operations has adjustable wheels that allow it to reposition itself to cope with changing conditions. The RSTAR (Rising Autonomous Robot Autonomous Robot) can switch between flat surfaces, climb large obstacles and walls and crawl through tunnels, pipes and narrow spaces

"The RSTAR is ideal for search and rescue operations in unstructured environments, such as collapsed buildings or flooded areas, where it must adapt and overcome various obstacles to reach its target, "says David Zarrouk, of the 39, Ben Gurion Negriq University, RSTAR, in a press release

The robot was presented at the Conference International IEEE 2018 Robotics and Automation (ICRA) Conference in Brisbane, Australia Sprawl in its name comes from the robot's legs RSTAR's legs are adjusted down and away from the horn ps, but can be adjusted to change the robot's center of mbad. When a robot can change his center of mbad, he becomes more varied in the tasks that he can perform and the movements that he can accomplish.

"By moving its center of mbad forward, RSTAR can climb steeper slopes without tipping over. RSTAR can also climb vertically into pipe environments and even crawling horizontally pressing on his wheels Zarrouk told IEEE at the conference

The RSTAR comes from the Zarrouk family of STAR robots, which are also built for rescue operations. In a real search and rescue operation, a robot often has to overcome several successive obstacles of different types to reach its target. We have built RSTAR with the mind that it should be simple, reliable and safe. He should be able to overcome several obstacles generally available without any external mechanical intervention. "
