Overview of the Humanoid League
The Humanoid League, a segment of RoboCup 2021, is set to unfold virtually from 24-27 June. This league features autonomous robots designed with human-like attributes, competing in soccer matches.
Understanding the Humanoid League
Maike Paetzel-Prüsmann, a member of the executive and organizing committees, provides insights into the league’s dynamics, its typical physical setup, and adaptations for the virtual event.
Humanoid Robot Specifications
The Humanoid League imposes strict regulations on robot design, aiming for human-like features. Robots must adhere to human body proportions, utilize bipedal locomotion, and employ human-like sensors, such as a maximum of two cameras.
Hardware Development
Teams in this league are responsible for developing their robots, often from scratch. While some may modify commercial platforms, most opt for custom-built solutions, making hardware innovation a key aspect of competition.
Evolution of Participation
Previous Participation Levels
In the 2019 physical event, the league featured three sub-leagues based on robot sizes: kid size, teen size, and adult size, totaling around 25-30 teams.
Streamlining for Efficiency
In 2020, the decision was made to merge the teen size league into the kid and adult size categories due to overlapping participation, resulting in two primary size classes.
Match Dynamics
Match Duration
Standard matches consist of two 10-minute halves with a five-minute halftime break. Knock-out stages may include extended time and penalty shootouts, extending matches up to 45 minutes.
Technical Considerations
Camera Placement
Teams are limited to two cameras placed within the robot’s head, adhering to specific field of view requirements. While some teams experiment with dual-camera setups, challenges in calibration often lead to reliance on a single camera.
Hardware and Software Diversity
Teams exhibit significant diversity in robot hardware, software, and methodologies, particularly noticeable in adult-size robots. Various approaches are employed to address challenges like stability and mobility.
Personal Involvement
Entry into the League
Maike Paetzel-Prüsmann joined the league in 2010 as a bachelor’s student, initially participating in the Standard Platform League (SPL) before transitioning to the Humanoid League in 2012.
Through these insights, the complexity and innovation within the Humanoid League become apparent, highlighting the ongoing evolution of robotics in competitive sports.
Evolution of the League
Over the years, the Humanoid League has undergone significant transformations, reflecting advancements in technology and competition dynamics.
Historical Changes
From the introduction of distinct field markers to alterations in field elements like goals and the ball, the league has witnessed substantial shifts. The transition from physical poles to artificial grass and the removal of localisation aids mark notable milestones.
Adapting to Challenges
Early stages of adaptation weren’t without hurdles, such as the struggle to resolve symmetry issues and instances of software failures during matches. These challenges spurred innovation and problem-solving within the league.
Transition to Virtual Environment
Addressing the Pandemic Challenge
The onset of the COVID-19 pandemic prompted a fundamental reevaluation of competition formats. With restrictions on physical gatherings and lab access, the league pivoted towards a virtual model.
Simulation as Solution
Embracing simulation technology offered a viable alternative. Leveraging partnerships with simulator developers like Cyberbotics, the league transitioned to cloud-based, 3D simulations for competition.
Virtual Competition Dynamics
Mimicking Real-World Constraints
To maintain authenticity, the virtual environment replicates real-world limitations. Strict sensor restrictions and limited information access ensure parity with physical competitions.
Enhanced Engagement
Through regular software updates and interactive features, teams remain actively engaged throughout the virtual event. Mock competitions and collaborative problem-solving sessions foster a sense of camaraderie and competition.
Future Outlook
Long-term Integration
The success of the virtual format prompts consideration for its continued integration post-pandemic. Options include establishing a dedicated 3D Simulation League or organizing intermediate virtual tournaments to complement physical events.
Sustaining Collaboration
Central to the league’s ethos is the spirit of collaboration and shared learning. Efforts to maintain this exchange between teams, both virtually and physically, remain integral to its future direction.
As the league navigates the complexities of virtual competition, it remains steadfast in its commitment to innovation, inclusivity, and the advancement of robotics research.
Pursuing the Humanoid League’s Ambitious Goal
The aspiration for robots to compete and potentially win the human world championship by 2050 seems lofty, but within the realm of possibility, according to insights from league experts.
Assessing Current Progress
Significant Gaps Remain
Observing the current state of robot performance, particularly in the adult-size category, reveals substantial disparities from the envisioned goal.
Incremental Advances
Despite existing gaps, the past decade has witnessed remarkable strides in research and development within the Humanoid League. This steady progress instills optimism for future advancements.
Path to 2050
Incremental Improvement
Sustaining the current pace of development could lead to significant achievements by 2050. While outright victory may be a stretch, the prospect of robots competing against humans becomes feasible.
Milestones on the Horizon
Attaining the capability to engage in competitive matches with humans by 2050 would represent a monumental milestone, even if victory remains elusive.
Reflection on Progress
Tangible Evolution
The visual nature of the league provides tangible evidence of progress. Comparing games from a decade ago to the present vividly showcases the advancements made in robot capabilities.
Inspiring Public Engagement
The transparency of progress within the league serves as a captivating narrative for the public. The tangible evolution of robot performance fosters intrigue and enthusiasm among audiences.
Continued Development
Embracing Challenge
The league continually evolves its rules and standards to challenge participating teams. This approach not only stimulates innovation but also provides opportunities for both new and established teams to advance their research.
Visual Representation of Progress
The league’s emphasis on visual progress serves as a compelling tool for public engagement. The stark differences observed over the years serve to inspire and captivate audiences, fostering support for ongoing research and development efforts.
As the Humanoid League navigates its journey towards the ambitious goal of competing on par with humans by 2050, the steadfast commitment to innovation and progress remains paramount. Through sustained dedication and collaboration, the league aims to push the boundaries of robotics research and propel the field towards unprecedented achievements.
