Hi, We are constructing an hexacopter drone and we would like to set simple mapping and obstacle avoidance with some IRs, sonars and a radar sensor. Almost all the libraries we have seen (hector, mrpt_slam) use ladars and/or the information processing is slow for a drone. In addition, is there any library to get the position changes of the drone using only an IMU? Do you have any suggestion on how to start? We are a little bit lost since we have never used ROS before. Thanks in advance! :slight_smile: --- [Visit Topic](https://discourse.ros.org/t/mapping-and-obstacle-avoidance-with-ir-sonars-and-a-radar-sensor/2716/1) or reply to this email to respond.
