After debuting its four-legged robot dog, Spot, on the market in 2020 for $75,000, it's now showing off the commercial version of Stretch, a warehouse box-moving robot that is available for purchase. > Stretch arrived in prototype form in March 2021, and after a year of on-the-job trials and more development, it was refined into a commercial product. The purpose of the bot is still the same: it's a box mover. Stretch is a warehouse worker that is meant to quickly take over unloading trucks, depalletizing boxes, and building orders without any need to build additional infrastructure.
