Abstract While effective miniature scale rocket motors have been developed, viable control surfaces at that scale do not exist. The goal of this project is to develop the necessary control system and actuators to enable autonomous millimeter to centimeter scale rockets. The proposed rocket control surfaces consist of electrostatic inchworm motors and planar linkages that are fabricated on a silicon-on-insulator wafer. These actuators will be driven by high voltage buffers and will be controlled by an electronic system consisting of a CMOS SOC, an inertial measurement unit, and a CMOS camera. We have developed preliminary simulations for the mechanics and control of the rocket, and we have fabricated the control surface actuators. These actuators were able to produce 1.575 uNm of torque, which corresponds to an equivalent aerodynamic force of 1.4 mN. Currently, we are characterizing the aerodynamic performance of these control surfaces using an integrated silicon strain gauge. We plan to integrate the control surfaces into a small model rocket to demonstrate their functionality.
