In many warehouses and e-commerce fulfillment centers, automated mobile platforms (AMPs) follow predetermined travel paths while moving payloads from one area to another. Because of the increasing prevalence of AMPs in industrial and material handling environments, Underwriters Laboratories published UL 3100, the Standard for Safety for Automated Mobile Platforms (AMPs), to help ensure AMPs can safely perform automated functions.
Mobile platforms covered by UL 3100 are intended for lifting, carrying, product picking, towing and similar activities. These actions may be provided by a gripping attachment, suction attachment, scope attachment or similar mechanism to lift or carry the load.
The first edition of the Standard provides requirements for applicable safety risks in industrial environments including hazard and injury prevention, as well as object detection and avoidance, risk assessment, functional safety, robotic payloads and product integration.
UL 3100 provides requirements intended to reduce fire risks, including containing any fire which occurs inside the product until it can be extinguished. Additional requirements help limit human contact with moving parts, pinch points, sharp edges, and components that would present a potential shock hazard.
The Standard also provides requirements for batteries and battery management systems (BMS) to help mitigate thermal runaway. AMPs use either lead-acid batteries or lithium-based batteries which, if rechargeable, are charged through a conductive system while either on-board or off-board the device. When the battery management system is included as part of a battery pack, the applicable battery standards (UL 2580, UL 2271 and UL 62133) will address the BMS.
Additionally, the Standard provides requirements for object detection and avoidance, to help ensure an AMP is able to mitigate the risk of injury and other hazards by detecting people and objects in its travel path.
Standards Technical Panel (STP) meetings
Members of the STP for UL 3100 include individuals representing companies and organizations from the United States, Canada, the United Kingdom, Denmark, South Korea, Austria, India and China. We aim to maintain a balance of participants, with no interest category comprising more than one-third of the STP membership balance. To improve the current balance for STP 3100, membership is still open to participants in the following interest categories: Authorities Having Jurisdiction (AHJ), Commercial/Industrial Users, Consumer, General Interest, Government, Supply Chain, and Testing and Standards Organizations. If you are interested in applying for STP 3100 membership or are aware of potential candidates for this STP, please contact the STP Project Manager.
The UL standards development process is open to anyone, and comments and proposals can be submitted at any time through our online Collaborative Standards Development System (CSDS). If you would like to propose changes to UL 3100, submit a Proposal Request at csds.ul.com.
UL 3100 is available for purchase and free digital access in English and French on the UL Standards Sales Site. The creation of a free account is required to access the digital view.

ANSI/CAN/UL 3100 was published on May 26, 2021.
STP 3100 members met several times, virtually and in person, from May 2019 through May 2021, to collaborate and revise the original document.
