The goal of this project is to create an affordable camera stabilizer (the “stabilizer”) for consumers to use with cell phones or GoPro cameras. The stabilizer compensates for two axes, pitch and roll, as well as vertical movement. The system (currently only compatible with one cell phone model) is handheld and uses a combination of brushless DC motors, an Inertial Measurement Unit (IMU), and a microcontroller to compensate for the operator’s movements, stabilizing the phone for nonshaky, high quality video recording. The stabilizer provides a lowcost alternative to professional stabilization solutions employed in the production of featurelength films; the system is designed for amateur video producers and enthusiasts to have access to physical camera stabilization. The final system is also intended to provide higher quality stabilization than the rudimentary physical (i.e. springs and counterweights) or software (postproduction) solutions available now. The stabilizer should run on 11.1V LiPo or NiMH batteries and require essentially no input from the user; only an “on” switch or plugging in the batteries should be necessary.
