We use an already known technology to achieve the required adhesion to the wall: A fast spinning impeller underneath the robot produces a strong vortex, which in turn causes a partial vacuum. We optimize the efficiency of the system using fluid dynamical simulation. Thereby, we achieve a considerably better performance than other robots of the same type. The resulting adhesion force reaches up to 40 Newton.


The jump off a low-rise building brings several technical challenges. Conventional systems are designed for higher altitudes and speeds than our robot will have to face. Thus, our solution contains a mechanism, which unfolds a paraglider already before the robot drops off the wall. Thin carbon profiles additionally support the opening of the paraglider. An elaborate control system provides for an optimal trajectory and a soft landing. In addition, a lightweight but robust shell out of fiber-reinforced plastics protects the robot against the impact.
