I wrote a node arduino that publish rpm and subscribe to cmd_vel with ros serial, and i can control my robot with teleop_twist_keyboard. and also i create a package with hector slam that visualise a map. now i want to add odometry to hector_slam for autonomous mapping . what can i do please? this is the file.launch of hector slam:
