Pickle Robot is building trailer-unloading robots into parcel dock operations

Pickle Robot raised a $50 million Series B in November 2024. The company said six customers had ordered more than 30 production unload robots in Q3 2024 for delivery in the first half of 2025, including pilot conversions, customer expansions and new customers. Source

Pickle unload systems had been operating at production capacity in distribution centers since summer 2023 and had unloaded more than 10 million pounds of merchandise by the November funding. The robots handle floor-loaded freight with mixed package shapes and irregular stacking patterns, the kind of dock work fixed automation has struggled to reach.

UPS said it was using Pickle unloading technology to make trailer unloading less physically demanding for employees while improving package care and reliability. Pickle says the robot unloads floor-loaded freight in as little as 90 minutes and moves dock-to-dock with setup under five minutes. Source

The Cambridge company grew from Andrew Meyer's MIT CSAIL research on truck unloading, with the target set on messy floor-loaded trailers. Tote lines and pallet flows are cleaner automation problems; Pickle is built for irregular package stacks where freight arrives without stable patterns or predictable orientation. The Series B added strategic investors including Teradyne Robotics Ventures, Toyota Ventures, and Ranpak, funding product features, commercial capacity, and geographic expansion.

Pickle’s dashboards show picks per hour, unload times and package mix to operators and supervisors while trailers are being unloaded.
