I'm looking into slam, rgbslam and autonomous teleop. In some of the packages i explored there is only a variable for base width.

My robot currently has a differential drive setup with the wheels in the front and castors in the back. how would the robot know it is not going to crash the back end into something when making a zero degree turn (each wheel is counter rotating)? is there a package or topic i have to modify and/or subscribe to, to make sure it clears obstacles in the rear.

I'm using a Microsoft kinect (facing forward) to play with slam and mapping, currently. I do not have rotary encoders on the motors yet.

Thanks for your help.

I closed this question because as it currently is, it's not ROS-related. With over 37,000 questions we try to keep them ROS-related. Unless you can update this to make it ROS-related, then you should probably ask this on a more general site such as
