Hi me and my team are beginner with ROS, we have some questions and we will be grateful if you could give us a little help.

our main work:

deminer robots ( contains two robot: one seeker robot that search area for mines and then calls another robot to grab it with a gripper and take it out from the map, note that the map has obstacles in it and robots must avoid them )

our gears:

1) kinect v1 , 2) rplidar a1 , 3) two wheel robots with encoders , 4) mini-pc with ubuntu 14.04 and ros indigo, 5) arduino nano

what we did till now:

reading and working on ros, rtabmap (Kinect + Odometry + laser and Kinect + Odometry + fake laser), gmapping, hector slam, navigation stack, object recognition kitchen, find object 2d/3d


1) best way to detect mines with kinect v1 ( we tried find object 2d/3d and ork )

2) best way to autonomous navigate and avoid obstacles/path planing ( most important problem, we stuck in this )

3) how to get encoders data/odometry from the wheels and use it in ros

4) best way to communicate between two robots in ros ( help about publish and listen )

in general we mostly need some insights about our main work, we partially know about our main work but we do not know how to connect all of this stuff together

Welcome! You are asking four very different questions here so you should split them up into four questions (vs. creating one question for four).
