SQuRo robotic rat to search for people under the rubble
A team of engineers led by Professor Qing Shi of Beijing University has designed a rat-like robot with enhanced mobility.
The SQuRo (an abbreviation for "Small-sized Quadruped Robotic rat") was the basis for the project. They took the body structure of rattus norvegicus (gray rat), which allows these animals to crawl into the narrowest crevices and climb through the rubble.
The robot has two degrees of freedom at the waist, the same on the head, and two more on each limb, allowing it to twist and squeeze through arbitrarily shaped crevices as narrow as 90 mm. Its turning radius is 0.48 body length.
SQuRo easily climbs inclined surfaces at a 15-degree angle, climbs over obstacles 30 mm high, and automatically gets up on its feet after a fall.
With its own weight of 220 grams, the robot rat can carry 200 grams of payload in the form of cameras and sensors.
Such a robot can penetrate through cracks in ruins and look for those who might be
