![]() This prevents the BionicWheelBot from grinding to a halt and ensures that it can keep moving forward even on rough terrain. ![]() ![]() The two legs that are folded up during walking are then extended, push the rolled-up spider off the ground, and continuously push it forward whilst rolling. In order to start rolling, the BionicWheelBot bends three legs on each side of its body to make a wheel. Just like a natural spider, the BionicWheelBot propels itself with a tripod gait, whereby it uses six of its eight legs to walk. The BionicWheelBot: transition from walking to rolling mode He has now further developed the kinematics and drive concept of the artificial spider together with Festo as part of the Bionic Learning Network. On the basis of these extensive studies, Rechenberg and his team first constructed a number of prototypes for the BionicWheelBot. Since the spider’s discovery, Professor Rechenberg has been working on transferring its movement patterns to technological applications. It is therefore ideally adapted to its surroundings: on even ground, it is twice as fast in so-called rolling mode than when walking. The flic-flac spider can walk like other spiders however, it can also move with a combination of somersaulting and rolling on the ground. Professor Ingo Rechenberg, a bionics professor at the TU Berlin, discovered it there in 2008. The biological model for the BionicWheelBot is the flic-flac spider (Cebrennus rechenbergi), which lives in the Erg Chebbi desert on the edge of the Sahara.
