Abstract:This thesis presents the design of a control system for the experimental setup of a wing from the Robird. The Robird is a robotic bird mainly used to scare off birds where they pose serious threats. It mimics the flapping motion of real birds through the use of 2 connecting rods mechanisms. They translate the rotational motion of the servomotors to the flapping motion of the wing. The twist angle of the wing can be created by having phase shift between the motors. The efficiency of the flapping depends on the frequency and twist angle. To increase the efficiency, experiments have to be done with different values for these parameters. The current experimental setup needs to stop the system in order to change the parameters. Designing a new “real time” control system to change the parameters while it is running would make it easier and faster to do the measurements. The control system takes in the frequency and the phase shift, and applies currents to the motors attached to the mechanism. The response should be under 4 seconds, the frequency should go up to 7Hz and the phase shift up to 10◦. It is designed using 20-sim and runs using 20-sim 4C. New components are chosen to better suit the new control system, they include the RaMstix to run the system and 2 motor controllers.
