Abstract:The Robird is a robotic bird made by Clear Flight Solutions (CFS) to scare off birds in areas where they cause harm. In order to further develop and evaluate design changes of the Robird and to inspect unmeasured states a representative simulation model is needed. This study presents a port-based modular model developed in 20-sim with use of an iterative approach, where themodel ismade and improved over six iteration that each specialize on a certain subject of interest. These subjects include rigid body dynamics, basic aerodynamics, motor and drive train, and compliant wings. The results of each iteration are evaluated using on-flight measurement data and visual simulations. Due to the quality of the measurement data it was not possible to guarantee the performance or accuracy of the model, however the simulations look promising and the model behaves as expected. In order to prove the model’s effectiveness for testing and evaluating design choices, the model is used to successfully evaluate a proposal for reducing the overall power requirements of the motor. This is done by adding a passive energy buffer that is parameterized by using optimization functions in 20-sim.
