When the half inch steel shaft bends just a little, it gets stuck. The proper linkage with a robust hinge can be bent and still retract.
The other option here is to incorporate some kind of shock absorption system that absorbs impact. I recall doing something like that on our 2013 robot when we didn't want cylinder shafts to bend as we ran into the pyramid to start our climb.
