2020-02-07 13:59:57 -0500 marked best answer How to make roscd go to ~/catkin_ws/devel instead of /opt/ros/kinetic?

I have sourced the setup.bash in the devel folder of catkin_ws but still the roscd command takes to /opt/ros/kinetic

On env | grep ROS, the output is:

ROS_ROOT=/opt/ros/kinetic/
ROS_PACKAGE_PATH=/home/username/catkin_ws/src:/opt/ros/kinetic/share
ROS_MASTER_URI=http://localhost:11311
ROS_VERSION=1

Indeed how do you make sure that the min velocity (forward or backward) is enough to overcome friction?

Did you hack into move base to add the dynamic reconfig for these? If yes, could you please share that part of the code?

2018-07-09 14:07:13 -0500 marked best answer How to add a static frame with respect to odom at the place of another frame?

I want to add a fixed placed at the same location of the camera_frame. The camera is attached to the robot and so is the camera_frame. However the frame moves along with the robot. I can add a static frame camera_frame_fixed at the location using a ROS node. The node would listen to the transform between the odom and camera _frame once, store the values, and then publish a static transform between odom and the camera_frame_fixed using these values. Is there another way to do this without creating a ros node?

The navfn does not use the footprint of the robot for collision checking though, right?
