Autonomous navigation, am I missing something ?
Hello everyone,
I'm trying to build an autonomous mapping and navigation robot with rplidar, arduino ( controlling the motors and ROS)
So far I I have got lidar, hector slam, hector exploration planner, and run the simpleexplorationcontroller and of course rosserial working fine
first question , I'm not sure if that all I need ?
Second question , generating the map and running hector exploration planner, and run the simpleexplorationcontroller,
I run rostopic echo cmd_vel
but I get zeros and values do not changes !
Any help will be appreciated , thank you

Please split into two questions. Have you worked through the navigation tutorial

I think the tutorial is different than what I'm trying to do, I don't think I need odometry with hector slam

True, but the tutorial won't give you a fully working anyway. The main point here is the understanding how thinks work. I'ld start with odometry and gmapping and later try to replace them with hector mapping.

Hi @hamzh.albar@gmail.com "I run rostopic echo cmd_vel but I get zeros and values do not changes !" I have this issue as well! Did you managed to solve it?
I had this 2 error info on my terminal![ERROR] [1594609714.183423593]: Received plan with zero length [ERROR] [1594609714.183452743]: Could not transform the global plan to the frame of the controller
