I'm with you until we get here. Attaching at the front of a long nose feels
like a bad idea. Any side force on the tow rope will tend to pull the robot off
course, and once slightly off course the force only gets worse. In any case, a
front-end tow rope attachment will want to be routed *under* the chassis and
drive axle, so that the "back flip" case doesn't turn into a spectactular
disaster.
At this point I'm going to quit speculating... I need to draw it out and write
up the equations to see it better. Or better yet, go build something.
