It was a busy week of news for robots in the supply chain last week. That includes:

• Schnuck Markets in St. Louis piloting a store robot that looks for out-of-stocks and pricing errors

• The logistics arm of Chinese ecommerce giant Alibaba shows off a "smart warehouse" using what looks to be a Chinese knock-off of the Kiva Systems machines acquired by Amazon in 2012

• Amazon hosts its third Robotic Picking Challenge for piece picking robots - see what team won the $80,000 prize.

We have videos of all three, from a report excerpted from our weekly supply chain video news broadcast from our Supply Chain Television Channel and CSCMP.
