Robots are very good at making small mistakes expensive. A misplaced cup is not just a misplaced cup. It can block the next object. A wrong order can violate a task constraint. A slightly bad coordinate can turn an elegant plan into a collision check failure. In software, you can often patch around the mistake and pretend this was always the architecture. In robotics, physics has a less forgiving product-management style. ...
