move_base publishes a cmd_vel with linear.z =2,and the other parameter is all 0
When i try to do a path planning with move_base, the output twist is changing quickly. Sometimes the output is correct, only the values of linear.x and angular.z, but after issuing a correct speed command, it will be overwritten by many wrong commands, the error command will publish a value of linear.z , the rest of the values are 0
