It stands 1.6 meters tall, has a screen for a face, and spends its working life moving boxes from one hospital corridor to another. Workerbot9, built by Berlin robot maker Pi4_robotics, was presented at the Deutscher Pflegetag nursing conference in Berlin on Nov. 12 and 13 as the centerpiece of a research project aimed at pulling routine errands off nurses' schedules at Charité, one of Germany's largest university hospitals, according to Heise.
The robot already exists in series production as a general-purpose service platform, with a loading surface, multiple obstacle-detection cameras, microphones and speakers. The project, called MuRoC, pairs Pi4_robotics with the Fraunhofer Institute for Manufacturing Engineering and Automation and Charité to add a robotic gripper arm, additional sensors and new object-recognition software so the machine can handle supplies on its own rather than simply ferry items a person has already loaded.
Built around what nurses actually asked for
Rather than starting from the robot's capabilities, the project team began with nursing staff. Researchers ran workshops with staff from intensive care and standard wards to identify which tasks a robot could realistically take on without disrupting ward routines, landing on two core jobs: checking and restocking supplies such as gloves and bandages, and basic patient interaction, including displaying information, reading aloud and monitoring vital signs on a screen.
Denny Chakkalakal, head of operations at Charité Healthcare Services, summed up the design philosophy bluntly: "A robot can only truly relieve nursing care if it fits meaningfully into station routines." That emphasis on workflow fit, rather than raw capability, distinguishes the MuRoC approach from humanoid-robot pilots elsewhere in hospital automation that have tended to showcase dexterity before proving ward-level utility.
From conference floor to trial ward
After its conference appearances, Workerbot9 moves to a trial ward at Charité for real-world testing, where the added gripper arm and sensors will be evaluated against the routines nursing staff described in the earlier workshops. The project sits alongside a broader wave of hospital-automation pilots in Germany and beyond, as hospitals facing nursing shortages look to robots for logistics rather than clinical decision-making.
Germany's hospital sector, like much of Europe, is contending with a persistent nursing shortfall, and MuRoC's backers are betting that offloading supply runs and basic monitoring, rather than attempting more ambitious clinical tasks, is the more defensible near-term use case. Pi4_robotics has not disclosed a timeline for deploying the upgraded Workerbot9 beyond the Charité trial ward, nor pricing for hospitals interested in adopting it.
