![]() As such, SABERs can address various tasks relevant to extraterrestrial missions, including exploration, outpost building and equipment maintenance. This design allows several SABERs to work cooperatively, extending capabilities of their mechanics or enlarging the working area. The manipulator configuration enables the robot to manipulate objects using two robotic arms with changeable tools. The rail trolley configuration allows the robot to overcome gaps larger than its wheel diameter, climb steps as large as the wheel radius, and pass through passages smaller than the wheel diameter. The monowheel configuration provides locomotion with a speed up to 10 km/h. SABER is a Step, Assembler, Bridge, Explorer Robot comprising a platform and a reconfigurable rail it can work in three different configurations: monowheel, rail trolley, and manipulator. This study proposes a heterogeneous modular reconfigurable robot called SABER that is suitable for future autonomous extraterrestrial missions. These merits, together with the robot’s high load-carrying capacity (5 times its weight), low cost, obstacle-crossing capability (as high as ~50% its length), and pressure resistance (70 kg), allow for a wide variety of applications. In addition to linear motion (~20 mm/s) and turning (50°/s) on a flat terrain, the robot can also maneuver on various surface conditions (such as gaps, smooth slopes, sand, muddy terrain, and water). The soft compliant structure and four locomotion modes make the robot ideal for maneuvering in congested or complex spaces. Our robot can realize four distinct gaits: horizontal tumbling for distance, vertical tumbling for height, imitation of gastropod writhing, and inchworm-inspired crawling for cargo delivery. Here, we demonstrate an insect-scale soft robot with multi-locomotion modes made by Ecoflex and magnetic particles, which can be actuated by a magnetic field. Despite the development of biomimetic principles for soft robots, how their shapes, morphology, and actuation systems respond to the surrounding environments and stimuli still need to be improved. Compared to traditional rigid robots, flexible robots are more adaptable and terrain-immune and can even interact safely with people. These robots can perform various tasks, such as carrying medicines and collecting information, according to their movements. He has studied the area for three decades.ĭiscovery of Cebrennus rechenbergi and its ability to perform cartwheels was profiled in the journal Zootaxa.Inspired by the efficient locomotion of insects in nature, researchers have been developing a diverse range of soft robots with simulated locomotion. He told the press he started crying when he saw the cartwheels performed for the first time. Rechenberg captured the first samples of the insects before he first observed the animal carry out the unusual behavior. The somersaulting robot is named after the Berber word for spider, tabacha.Īmazingly, the tiny animals are also able to create structures to shade itself in the desert. In unusual conditions like collapsed buildings or mines, the action could help small robots avoid obstacles. It is able to either walk or tumble, depending on which offers the most efficient method of transportation in varying environments. Tabbot is designed to test the nature-inspired technology that could, one day, be used on robotic craft in the depths of the ocean or the surface of Mars. Rechenberg was so impressed by the ability of the spider to perform this act he designed a new robot, able to perform cartwheels. Although the spiders regularly acted out the behavior in the desert, the act was rarely performed in a laboratory setting. Golden wheel spiders, related to the flic-flac, can cartwheel downhill, but the newly-discovered species can perform the move while traveling upward, as well. So far, the new species has only been seen in the Erg Chebbi region where Rechenberg first encountered the organisms. These are known for their hunting abilities. ![]() ![]() The spider researcher conducted a careful analysis of the creatures.Īfter confirmation of Rechenberg's discovery, the species was classified as a new form of Cebrennus, or huntsman spiders. Rechenberg brought specimens to Peter Jäger, of the Senckenberg Research Institute in Frankfurt, Germany. When performing this strange behavior, the tiny creatures can travel up to 6.6 feet per second. ![]()
