Undulation forces from longitudinal fins also let the BionicFinWave maneuver itself forward or backward. Knowledge gained in this project could also find use in the manufacture of soft-robotics components. Swimming autonomous robots such as the BionicFinWave could eventually find practical application in inspection, measurement, and data acquisition in water, wastewater, and other process industries. Its propulsion mode lets the underwater robot autonomously maneuver through water-filled acrylic tubing. Deft underwater navigation by soft-finned robotįor the 15-oz BionicFinWave, the Festo Bionic Learning Network team found inspiration in the undulating fin movements of marine animals such as the polyclad and cuttlefish. The robot rolls faster than it walks and can roll up a 5% incline. An inertial sensor lets the robot track its current pose so it accurately times its next push-off sequence. Two lower-middle legs are folded up during walking then extend and push the rolled-up spider off the ground to propel it forward. To start rolling, the BionicWheelBot bends three legs on each side of its body to form a wheel. Just like living flic-flac spiders, the Festo BionicWheelBot propels itself with a tripod gait using six of its eight legs to walk. The biological model for the BionicWheelBot is the flic-flac spider Cebrennus rechenbergi) - a species that lives in the Erg Chebbi desert on the edge of the Sahara. ![]()
