So now the question is, who made the original Sentinels? If the Tenno found them, and Orokin versions exist, it must have been during the Great War, or shortly before that, because the Tenno didn't even get their Warframes all that long before/ right when the Sentients returned from Tau to kill the Orokin who betrayed them. Judging by how most of them look my guess is that they are actually Sentient drones made to maintain the insides of Sentients.
