the robot was finished doing so, it was able to differentiate their proper locations. for example, after examining the various shoe places in front of it, the robot was able to grasp where exactly the laces should go, allowing it to be able to tie shoes later on.
this might all sound too good to be true, but behold, science has won again! these robots may not be accessible to everyone, but the very thought of these coming to creation is beyond amazing.
