The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.

第一是泛化：料箱颜色、尺寸、新旧程度都不同，能不能用同一个模型稳定完成识别、抓取与搬运。第二是导航：搬起之后从A点到B点怎么走，路径规划、避障，途中被打断后能不能续做。第三是策略理解：比如“从面前100个箱子里搬走50个”，机器人能不能理解数量、以及该选择哪50个箱子，到目的地怎么码放，以及放下后要不要把物体取出等等，每个环节都存在问题。。关于这个话题，爱思助手下载最新版本提供了深入分析
