serow_ros readme problem

[subetter]

hello, when I try to use reproduce your work, I met 3 problems.

1. in your README below serow_ros,there is no any publisher example for us. could you please provide some demo?
   Robot State Publisher (e.g. topic: /joint_states)
   IMU (e.g. topic /imu0)
   Feet Pressure or Force/Torque sensors for Center of Pressure (COP) computation in the local foot frame (e.g. topics /left_leg/force_torque_states, /right_leg/force_torque_states)
2. The link about valk_bagfile and nao_bagfile can't open.could you please provide a new link? many thanks.
3. could you please provide more details about gazebo sim?
   I am looking forward your early apply! Thanks very much again!!!
