What Are Service Robots?

Service robots are robots designed to perform useful tasks for humans or equipment in settings outside conventional industrial automation, ranging from domestic households and healthcare facilities to retail environments and public spaces. ISO 8373:2021 defines a service robot as "a robot in personal use or professional use that performs useful tasks for humans or equipment," distinguishing the category from industrial robots by intended application rather than by hardware configuration. A service robot operating in a hospital performing medication delivery is classified as a professional service robot; the same platform configured for home assistance falls under personal use. The degree of autonomy ranges from partial, where a human operator monitors and intervenes, to full, where the system completes its task without active supervision.

Service robots draw from mechatronics, control theory, computer vision, and artificial intelligence. They typically operate in unstructured environments populated by untrained users, which imposes requirements for safe physical interaction and adaptive behavior that industrial robots, working behind safety barriers, do not face.

Mobile Service Robots

Mobile service robots navigate autonomously or semi-autonomously through physical environments to carry out tasks that require displacement rather than fixed-station operation. Applications include floor-cleaning robots that map interior spaces, delivery robots that transport packages or medical supplies along corridors, and inspection platforms that traverse outdoor infrastructure. The IEEE Robotics and Automation Society's technical committee on mobile manipulation defines mobile manipulation as the synergistic combination of navigation and physical interaction with the environment, noting that it demands autonomous solutions based on onboard sensors, generalization across varied scenarios, and robustness to the inherent uncertainty of large interactive spaces. Simultaneous localization and mapping (SLAM) algorithms form the navigational core of most contemporary mobile service robots.

Manipulation and Physical Assistance

Service robots that perform physical work on objects or directly assist human bodies require manipulation capabilities: end effectors, articulated arms, and perception systems that can identify, locate, and grasp items in cluttered, variable environments. Surgical robots, rehabilitation devices, and logistics robots that sort and retrieve items in warehouses all fall into this sub-area. Physical safety is a primary design constraint, as manipulators operating near people must comply with force limits and detect unexpected contact. The International Federation of Robotics service robotics report documents growing adoption across healthcare and logistics, where the volume of physically repetitive or precision tasks makes robotic manipulation economically viable alongside human workers.

Wearable and Collaborative Robots

Wearable robots, including powered exoskeletons and rehabilitation orthoses, attach directly to the human body to augment physical capability or support recovery from injury. Unlike free-standing service robots, wearable systems must continuously sense the wearer's intended movements and respond in real time, integrating compliance control and intention recognition. Collaborative robots (cobots) are a related category designed to share a workspace with human operators, using force-torque sensing and speed monitoring to avoid causing harm during joint tasks. Research on human-robot collaboration in service settings, including work highlighted through IEEE Innovation Spotlight on service robots, has identified environmental perception, compliance control, and intention recognition as the three core technical capabilities required for effective cohabitation.

Applications

Service robots have applications across a wide range of sectors, including:

• Healthcare and eldercare, assisting with patient transfer, medication delivery, and rehabilitation
• Home automation, performing floor cleaning, lawn maintenance, and security monitoring
• Retail and hospitality, managing inventory, guiding customers, and delivering food
• Industrial process control support, carrying out inspection and material transport in semi-structured facilities
• Education and training, serving as physical platforms for engineering and programming instruction
