Abstract
An inertial measurement unit (IMU) device includes an IMU sensor, a controller, a temperature sensor electrically connected to the controller, a heat source, and a heat conductive member. The controller is configured to, in response to a temperature of the IMU sensor detected by the temperature sensor falling below a threshold temperature, control the heat source to generate heat. The heat conductive member is configured to transfer heat from the heat source to the IMU sensor, and includes an electrically insulating and thermally conductive material.
