ECE students create handheld, self-stabilizing camera platform
As an ECE 4760 project, Cornell ECE students Evan Chen, Geo Xu and Zequn Huang, created a handheld self-stabilizing camera platform using two high-torque servo motors, a gyroscope, an accelerometer, and a wooden frame.
As avid outdoor enthusiasts, they often find themselves taking action shots of their adventures, only to discover a very shaky and nauseating video of their endeavors at the end of the day. So, for their project, they decided to create a handheld self-stabilizing camera platform. The device will keep a camera in a steady neutral position even if the user is not holding the device steadily while in motion.
The device consists of a gyroscope and an accelerometer mounted on a platform, allowing the device to accurately determine the pitch and roll of the platform. This platform is connected to two servo motors, where one motor controls the pitch of the platform while the other motor controls the roll. Once the sensors detect a disturbance in the position of the platform, it sends the data to a microcontroller, which then controls the motors to counteract the disturbance and keep the platform in the level position.
Their project has been published in the September 2014 issue of Circuit Cellar Magazine. See it here: http://circuitcellar.com/inside-this-issue/
