Impossible goal: This seemingly fun wiki entry on funky lacing types, got me thinking. Tying laces is really, really hard, it takes humans years to learn how to do it. You have to balance, stretch down to your feet, manage fiddly little holes, wobbly laces and tie knots.What hope a robot, I mean all these walking up stairs, balancing on slippery ice robots are uber cool, but get one to put on a pair of shoes and humans are history.
