sonar sensor ?

Open Arvrairobo opened this issue 4 years ago • 28 comments

First of all great book and learnt many concepts from it but still somethings are confusing which i have listed below, if you can give me insights on it, that would be great.

i have seen the code and i am not getting some things in the code, if you could shed some lights that would be great.

  1. i do see the sonar sensor that we are reading from arduino and receiving that in launch_node.py file and also publishing the sonar data on topic, but i dont see where it is subscribed and where that reading is been used?

  2. there are 3 cliff sensor joint used in the xacro file which is left, right and front joint, what is that used for and how it is used in the real robot? also i dont see sonar sensor used in the xacro or urdf.

  3. when i tried to run the the code on gazebo simulator with hotel map and viewed that on rviz, robot was able to move to the goal but it was taking lots of time and sometimes its just stuck on its place, spinning many times and then find new goal and then it goes to end goal but it was not that great, what is wrong with it?

Looking forward to hear from you.
