The US Army has wrapped up a structured study designed to shape the next phase of its Small Multipurpose Equipment Transport (SMET) program, gathering frontline feedback to refine how the robotic “mule” performs in the field.
The study assessed how troops interact with SMET Increment I, through unit outreach, surveys, and interviews, supported by analysis of operational data.
It focused on four core questions, including which aspects of the current SMET soldiers find most useful and how units employ the system in real-world operations.

It also examined what improvements are needed to make the system easier for soldiers to adopt and which enhancements would provide the greatest value in future missions.
The goal? To collect data across a wide range of units, producing a representative dataset for both quantitative and qualitative analysis to inform future procurement decisions.
Advancing the Robotic Mule
The S-MET is a single radio-controlled, eight-wheeled platform designed to transport payloads and supply power to organic electronic systems.
Its first increment can carry up to 1,000 pounds (454 kilograms) of equipment, supporting Infantry Brigade Combat Teams, Explosive Ordnance Disposal units, and Security Force Assistance Brigades.

The next increment aims to build on that baseline by doubling payload capacity while integrating upgrades identified through operational use and evaluation.
Planned improvements include increased exportable power to support systems such as unmanned aerial platforms and communications equipment.
Additional enhancements include reduced acoustic signature, a dismounted wireless mesh communications network, and compatibility with global grid charging systems.
