Ignore the fact that catch usually means exceptions which usually means some kind of failure. A piece of code is running and it just started some work that’s going to take a long time in the background, there’s no point waiting and the program can do something more useful while the stuff happens in the background. It “throws” an exception that is caught by a scheduler multiple layers of function calls up the stack. The scheduler saves the return address into a list of pending work to get back to, and then goes to find something that it can make progress on. Eventually it completes the other work and is signalled that our background task is complete. It pops the return address off the list and jumps to it, continuing the function call exactly where it left off as though nothing happened.

问题在于，具身智能没有大模型那样的数据体量去覆盖所有光照变化。但换个思路，如果模型能关注局部信息——比如只锁定每瓶水的外观特征，而不关心背景、光线、桌子颜色——就能避免被全局变化干扰。这正是我们做“热力图”的出发点：让模型聚焦操作对象本身，而不是整个画面。
