The Italian Institute of Technology (IIT) has unveiled the ergoCub robot, a new humanoid robot designed to minimize the risk of musculoskeletal disorders (MSDs) in industrial and hospital settings. This innovative robot builds upon the legacy of the iCub, a child-sized humanoid robot that served as a platform for earlier advancements in humanoid robotics research at IIT.
Design Philosophy of ergoCub
The ergoCub stands 1.5 meters (4.9 feet) tall and weighs approximately 55.7 kilograms (123 pounds). Unlike other humanoid robots like H1 robots designed for tasks requiring strength or speed, the ergoCub prioritizes ergonomics. Its design minimizes the energy required for humans and robots during collaborative lifting tasks. This focus on ergonomics aligns perfectly with the project’s core objective – preventing injuries caused by repetitive or tiring physical labor.
Capabilities of the ergoCub Robot
The ergoCub is equipped with several features that enhance its ability to collaborate with humans in various workplaces:
Artificial Intelligence (AI):Â
The ergoCub utilizes AI to assess, manage, and reduce the risk of physical strain on workers. This allows the robot to adapt its movements and assistance based on the specific task and the worker’s physical limitations.
Wearable Technologies:Â
The ergoCub project integrates easily with wearable technologies designed to monitor worker biomechanics. The robot can provide targeted support and intervene when necessary to prevent injuries by analyzing real-time data on posture, muscle activation, and strain.
Arms and Object Manipulation:Â
The ergoCub possesses two dexterous arms capable of precisely holding and moving one object. This allows the robot to lift, hold, or transport materials, reducing the physical burden on human workers.
Advanced Sensors:Â
The robot has various sensors, including an Intel RealSense camera for depth perception and LiDAR for navigation. These sensors enable the ergoCub to operate safely and effectively in diverse environments.
High Payload Capacity:Â
Despite prioritizing ergonomics, the ergoCub can still carry loads of up to 10 kilograms (22 pounds). This allows it to assist with a wide range of tasks requiring advanced object management.

Applications of ergoCub Humanoid
The ergoCub’s capabilities make it a valuable asset in various industrial and hospital settings. Here are some possible applications:
- The ergoCub can assist with repetitive tasks on assembly lines, reducing the risk of MSDs for human workers.
- The robot can help lift and transport materials, minimizing strain on construction workers.
- It can assist medical professionals with patient care tasks, particularly lifting or moving patients.
While the primary focus of the ergoCub lies in preventing physical injuries, the researchers at IIT envision broader applications for this unique technology. The AI capabilities and sensor data collected by the robot can be used to:
- By analyzing worker movement patterns and identifying potential risks, the ergoCub can inform the development of personalized training programs to improve worker ergonomics and further reduce injury risk.
- Data collected by the ergoCub can provide valuable insights into workplace layout and task design. This information can be used to optimize workplaces for better ergonomics and worker safety.
- The ergoCub is a valuable platform for further research into safe and effective collaboration between humans and robots in various work environments.
Team Behind ergoCub
The ergoCub project is a collaborative effort between IIT and INAIL (Istituto Nazionale Assicurazione contro gli Infortuni sul Lavoro), the Italian National Institute for Insurance against Accidents at Work. INAIL has provided significant financial support for the project, reflecting the organization’s commitment to workplace safety and preventing occupational injuries.
