How do you plan to determine a global pose for the robot? Using only wheel encoders will quickly lead to a lot of error in the pose estimate.

HI bribri. By far of my knowledge, it would be ok to perform the navigation as long as if the robot you are handling with is lidar installed. If lidar is installed, then localization such as the ndt_matching package will have the ability to detect the current location of the robot (however, you need to publish your robot's state manually, check our ndt_pacakges). Imu, however, will be aiding in generating local maps in advance which might hamper the performance of the navigation. In conclusion, you probably wanna need IMU for accurate navigation control for the future. Good luck
