I think that I got the basic of my ros project!
I have it such that it will tell me what the distance is at 180 degrees, will convert that to a string (a if >0.3, b if <0.2, c if in between) - figure a- and then a script to convert the string output published in the cmd_vel topic - figure b. rviz shows my data points appropriately. My rqt graph is what I was hoping it be -figure c. However I either get no movement on my robot, or a counterclockwise angular movement without linear movement. I think the problem must something with my callback script in figure b but I cant figure it out. I think its a simple syntatical error but I need some help
Thank you so much for any help. I feel that I am close!
