As humanoid robots continue developing in labs worldwide, one mobile robot has already made a tangible impact in healthcare. Diligent Robotics, based in Austin, Texas, recently announced that its Moxi robot has completed a remarkable 110,000 autonomous elevator rides in health systems across the United States. This achievement is a testament to advancements in artificial intelligence and robotics, particularly in the challenging, unstructured environments of hospitals.
The Moxi robot, described as a mobile manipulator, is equipped with a single arm enabling it to perform tasks such as opening doors and operating elevators. According to Andrea Thomaz, CEO of Diligent Robotics and a veteran of artificial intelligence with over two decades of experience, achieving robotic autonomy in a healthcare setting is no small feat. "Navigating elevators may seem mundane, but the dynamic and often unpredictable nature of shared spaces makes it a challenging task for robots designed to operate alongside humans," Thomaz explained.
One of the critical aspects of Moxi's development has been its integration into existing healthcare workflows. Since its founding in 2017, Diligent Robotics has focused on embedding Moxi into hospital operations to help staff deliver supplies and transport laboratory specimens around the clock. This, the company claims, has contributed to improved operational efficiency, allowing healthcare professionals to dedicate more time to patient care rather than routine transport tasks.
Diligent Robotics adopted a development strategy reminiscent of Tesla's approach to innovation. Instead of deploying a fully finalized product straight out of the research and development phase, the company opted to incrementally enhance Moxi's autonomy through real-world experience and remote supervision. "This milestone signifies that we've moved beyond R&D—our robots are now actively working in production environments," Thomaz stated.
Initially, deployments required Diligent staff to supervise the robots on-site closely, acquiring labeled data essential for refining AI models. However, as Moxi's capabilities expanded, the need for direct supervision diminished. Today, Diligent Robotics' fleet of 100 robots operates across 20 sites without the need for human presence, a testament to the advancements in their autonomous capabilities.
The journey to achieve this level of autonomy faced numerous challenges, especially concerning Moxi's ability to manipulate various elevator systems. From simple button pushes to badge-scanned access in secure areas, Moxi's capability to navigate these intricacies has been refined over time. "Elevators have become a roadmap for autonomy," Thomaz noted, emphasizing that nearly every delivery involves engaging with an elevator system.
The real-world application of Moxi's skills in handling different elevator models is helping Diligent Robotics develop specialized models for broader competencies in robotic manipulation. These foundational models pave the way for potential expansion into other skill sets, allowing Moxi and future robotic iterations to navigate even more complex environments efficiently.
Despite overcoming many technological hurdles, hospitals remain challenging settings for robots due to strict safety regulations and the constant presence of both trained personnel and patients. Diligent Robotics has thus approached these deployments with significant caution. For example, interventions are in place for healthcare professionals to pause or redirect robots in emergencies, such as urgent patient transport needs.
To address common challenges, Diligent Robotics recently introduced a feature allowing Moxi to display a screen message requesting assistance to continue its task if stopped. Additionally, data collected on elevator usage enables Moxi to avoid busy routes, optimizing its operations based on time-specific patterns.
The implications of Moxi's success extend beyond current applications. As the demand for automation escalates due to aging populations and workforce challenges, robots like Moxi highlight the potential for robotics to address essential human needs. Thomaz envisions a future where humanoid social robots will enhance care delivery across diverse settings. "We're only scratching the surface of what humanoid robots like Moxi might achieve," she asserted. "The trust and knowledge we build in healthcare settings today will be invaluable for future developments."
With Moxi already a familiar presence in many U.S. hospitals, the initiative by Diligent Robotics suggests an evolving healthcare landscape where human-robot collaboration might soon become the norm.
