Hi, @ZacharyTaylor
May I ask if you could include a build instruction and how to run this with our own data? Having some issues with running it and unaware if I have build it correctly
Best Regards,

Thanks for your great work.
I want to use this package but I have a little confused about imu_bias
topic.
void OdomPredictor::imuBiasCallback(const sensor_msgs::ImuConstPtr& msg) {
tf::vectorMsgToKindr(msg->linear_acceleration,
&imu_linear_acceleration_bias_);
tf::vectorMsgToKindr(msg->angular_velocity, &imu_angular_velocity_bias_);
have_bias_ = true;
}
If referring to the imuBiasCallback
function, the angular velocity and acceleration of the imu seem to go into the value of bias as it is.
So is it correct that I understood?
May I know why the value of imu is included in the bias value without any bias estimation?
I'd appreciate it if you could give me an answer.
