Speaking as someone who knows farmers- they do, in fact, consider going into the silo a dangerous task, because everyone knows some family that had someone die because of it. They do it anyway, because it needs to get done, but they are quite aware of the risk. Everything on a farm has to earn its keep in terms of ROI, and so will this robot. It may or may not be cost effective, and we'll see. But please don't downplay the very real danger, just because some folks have to manage it because of their job.
