A device, system, and method may orient a device in-vivo. A ballast or other weight may be rotatable or otherwise movable within a ballast chamber within a device. An induced magnetic field may be used to shift and/or rotate the ballast weight. Rotation and/or shifting of the ballast weight may position the in-vivo device in a specific orientation. The rotation and/or shifting of the ballast may be controlled by circuitry within the in-vivo device and/or by external signals transmitted to the in-vivo device.
