ROI per square foot, not per keynote. IAM Robotics' May 31, 2022 grant US11348066B2 claims piece picking and put-away with a mobile manipulation robot — navigation and grasping fused into a single autonomous unit.
Read the ROI in the architecture. The CPC tags span both worlds: B25J 5/007 and B25J 9/1692 mobile manipulators, B25J 15/06 grippers, plus G05D 1/0088 and G05D 1/0248 autonomous navigation. A fixed-base arm replaces a picker; a mobile arm replaces the picker and the cart that feeds it.
The capex read is that mobility multiplies the labor displaced per machine. A stationary pick cell still needs goods brought to it; a mobile manipulator goes to the goods. That changes the labor-replacement ratio, which is the numerator of every warehouse-automation payback calculation.
For a public-equities reader weighing fulfillment automation, the combined platform is the more capital-efficient bet — one robot doing two jobs amortizes better than two single-purpose machines. This patent is the architecture that makes that math work.
The honest limit: the grant describes the platform, not its throughput, reliability, or cost. Mobile manipulators are harder to build reliably than fixed arms. The ROI case depends on uptime the patent cannot promise.
The takeaway for the money desk: in warehouse automation, the returns concentrate where one machine replaces multiple labor functions. Mobility plus manipulation in one unit is where the boring-robot ROI actually lives.
