Hospitals Look to Robots as OR Pressure Mounts

A robotics acquisition highlights hospitals’ growing reliance on service robots to keep ORs running smoothly

21 Jan 2026

US hospitals are reassessing how operating rooms operate, and a recent robotics acquisition has drawn attention to that shift as staffing pressures persist across the healthcare system.

Serve Robotics’ acquisition of Diligent Robotics highlights what executives and analysts describe as a new phase of hospital automation. Rather than focusing on complex surgical machines, the deal underscores growing interest in service robots that support operating rooms by handling routine tasks and reducing workflow disruptions. Financial press reports say the transaction is expected to close in early 2026, though financial terms have not been disclosed.

Hospitals have struggled to maintain operating room efficiency as shortages of nurses and technicians persist. In many facilities, clinical staff spend large parts of their shifts on logistical work, such as delivering supplies, transporting instruments and resetting rooms between procedures. These activities can slow case turnover and add to staff fatigue.

Diligent Robotics’ Moxi robots are designed to take on such tasks. The robots deliver supplies, make trips to laboratories and central supply areas, and respond to on-demand requests, allowing clinical teams to remain closer to patients and operating suites.

Health systems including Northwestern Medicine and ChristianaCare have deployed Moxi robots to support perioperative teams. At these hospitals, the robots are used to deliver sterile supplies, retrieve medications and assist with room turnover during busy surgical schedules. Hospital leaders say the technology has helped reduce interruptions and improve consistency in operating room timetables.

Serve Robotics brings experience in managing large robot fleets using cloud-based software that monitors performance across multiple sites. Analysts say this capability will become increasingly important if hospitals move beyond pilot projects and deploy service robots across entire campuses. They argue that the long-term value lies as much in scalable fleet management as in the machines themselves.

The timing of the deal reflects broader pressures on hospital operations. Surgical volumes are rising as delayed procedures return, while labour markets for healthcare workers remain tight. Autonomous service robots are therefore being viewed as a way to improve efficiency without increasing headcount.

Industry analysts expect service robots to become a more common feature of hospital operations, particularly around operating rooms. As adoption grows, such systems are likely to play a low-profile but increasingly important role in supporting surgical care delivery.
