5 best cobot palletizers in 2025: TL;DR
What is a cobot palletizer?
A cobot palletizer is a collaborative robot system that automates the task of stacking products onto a pallet. These systems are designed to work safely alongside human workers, often without the need for extensive safety caging.
Unlike traditional palletizing robots, cobots use built-in sensors, force control, and vision systems to detect human presence and adjust their speed or stop when needed. This makes them ideal for small and mid-size production lines where space is limited and workers need to access the palletizing area.
They're easy to program through no-code interfaces, compact enough for tight layouts, and flexible enough to handle boxes, bags, or cartons of varying sizes. The result is reduced workplace injuries, lower labor costs, and continuous operation without the footprint or complexity of traditional robotic palletizing.
