I am using ultrasonic sensor to avoid obstacles like glass in my robot. so i have added range sensor layer in costamp. when the obstacle is placed in front of the sensor layer is formed and after removal of the obstacle the layer is not getting removed. I have attached the hardware programming file and params files that I have used. Please help me solve this problem.
