It turns out that robots are excellent mimics. ___(2)___ unless engineers also program them to adjust to ___(3)___ possible bump and nudge, robots don’t necessarily know how to handle these situations. Now MIT engineers are aiming to give robots a bit of common sense when faced with situations ___(4)___ push them off their trained path. They’ve developed a method that connects robot motion data with the “common sense knowledge” of large language models. Their approach ___(5)___ a robot to logically parse many given household task into subtasks, and to physically adjust to disruptions within a subtask.
