Not Robotic But had RP in 2001. 6 weeks later I sat on the saddle and got off it very quick. That was when I was introduced to the anatomical saddles with the cutaway- and 2 weeks later was doing a 25 mile offroad ride with only a bit of butt pain.

That was the good news---- For the next 5 years I had trouble finding a saddle that was comfortable for more than two weeks. The internal re-shaping meant that I was tender after about 200 miles on every saddle I tried.
