At the 2026 World Robot Conference, parcel sorting and bin handling were among the most crowded embodied intelligence exhibition tracks, with more than a dozen humanoid robots sorting express parcels. The article notes that in the first half of 2026 there were 322 financing events in China's embodied intelligence sector, totaling about 935 billion yuan, 5 times that of the same period last year, while most prominent robotics stories remain in laboratories and demo scenes. It cites Denver International Airport, whose plan to eliminate manual luggage handling led to luggage sent to wrong destinations, jammed shuttles, crushed parcels, a 16-month opening delay and more than 1 million US dollars in daily interest and maintenance fees for an idling facility, and Tesla's Fremont Factory in 2018, where a robot placing a soft fiberglass pad on the battery pack often failed to grasp or mispositioned it, dragging down production, before Elon Musk asked whether the pad was necessary and comparative tests showed installing or removing it made no difference to in-vehicle noise. The article says both cases show that when a single unit or single thread cannot match the pace of the entire system, advanced technology becomes a burden, and asks how far Physical AI is from real implementation as task bases and environments scale.
