Romeo is a 1.46-meter tall humanoid research platform developed by Aldebaran Robotics (now SoftBank Robotics) designed to explore and develop capabilities for assisting elderly and disabled individuals. The robot features 37 degrees of freedom, advanced sensors including cameras and sonars, and hands capable of grasping objects. Romeo serves as an open research platform for universities and research institutions working on autonomous assistance, human-robot interaction, and mobility aid technologies.

Released: 2016

Overview

Romeo represents Aldebaran Robotics' ambitious venture into full-scale humanoid robotics for real-world assistance applications. Standing at 1.46 meters tall and weighing 40 kilograms, Romeo was designed as an open research platform to advance the state of autonomous personal assistance for elderly people and those with loss of autonomy. The project brought together a consortium of research institutions and industrial partners across Europe to tackle the complex challenges of bipedal locomotion, object manipulation, and safe human-robot interaction.

Unlike consumer-focused robots, Romeo was explicitly developed as a research tool to explore cutting-edge technologies in areas such as cognitive systems, navigation in human environments, and physical assistance tasks. The robot's human-like proportions and articulated hands enable it to interact naturally with environments designed for people, from opening doors to picking up objects. Romeo serves as a testbed for algorithms and behaviors that could eventually be deployed in practical assistance robots.

The Romeo project emphasizes openness and collaboration, with the platform made available to research laboratories worldwide. This approach has enabled diverse research groups to contribute to advancing humanoid robotics while sharing insights on locomotion control, perception systems, and task planning for assistance scenarios.

Key Features

37 degrees of freedom: Enabling natural, human-like movement throughout the body including articulated fingers for grasping
Bipedal locomotion: Walking capabilities designed for navigating home and care facility environments
Multi-modal perception: Equipped with stereo cameras, RGB cameras, and sonar sensors for environment awareness and object recognition
Anthropomorphic design: Human-scale dimensions allowing interaction with standard furniture, doors, and household objects
Advanced hands: Multi-fingered hands with force sensors enabling delicate object manipulation and handover tasks
Open research platform: Accessible SDK and development tools for academic and industrial research collaboration
Inertial measurement unit: Ensuring balance control and stability during walking and manipulation tasks

Applications

Romeo was specifically conceived for research into assistance robotics for dependent individuals, particularly elderly people and those with physical disabilities. Target scenarios include helping with daily living activities such as fetching objects, providing mobility support, monitoring well-being, and enabling greater independence for people in home care or assisted living facilities. The robot's ability to navigate typical indoor environments and manipulate everyday objects makes it suitable for exploring practical assistance tasks.

Beyond direct assistance, Romeo serves research institutions investigating fundamental challenges in humanoid robotics including bipedal balance control, whole-body motion planning, human activity recognition, and natural human-robot interaction. Universities and labs worldwide use Romeo to develop and validate algorithms that advance the broader field of service robotics and autonomous assistive systems.

Technical Highlights

Romeo's technical architecture reflects the complexity of creating a capable humanoid research platform. The 37 degrees of freedom are distributed throughout the body, with particular attention to the hands which feature multiple articulated fingers with integrated force sensors for controlled grasping. The sensory system combines multiple camera types with sonar and inertial sensors to provide rich environmental perception necessary for autonomous navigation and manipulation in unstructured human environments.

The robot's bipedal walking system represents significant engineering achievement, incorporating dynamic balance control and adaptive gait algorithms that allow Romeo to walk on various surfaces and recover from disturbances. The open software architecture, based on NAOqi framework and compatible with standard robotics middleware, enables researchers to implement and test novel algorithms for perception, planning, and control while benefiting from a robust baseline system developed through the collaborative Romeo project.
