Navigation with Localization Module
Hi There,
We are designing some mobile tricycle robots that move around in a known environment, with max 3 of them that will work at the same time; we are using a master ROS for the planning and specular nodes with different ID on the 3 robots. After 1 month of research and closed doors I'm here to ask for advices.
Actually we will not have LiDARs mounted on, because they would interfere with each other (can't find LiDARs with editable laser frequency), but there will be a map created before with random laser scan. They will be equipped with BLE localization modules, with max 10 cm error on actual position, plus inertial sensors and encoders data; we suppose to have an accuracy of 5-7 cm radial error. We spent a lot of time thinking on our own navigation algorithms, and we found some nice ideas, but at the same time we would like to be sure that no libraries or cross-cutting approach exists, before moving full time on that.
Are there any navigation libraries or approaches that uses just two planar coordinates to navigate in a map?
Is it possible to implement a smart anti collision software using 7 ultrasonic distance sensors (5 placed on the front 2 on the back)? Are there libraries for ultrasonic sensors?
