Bringing science fiction to life through robotics has always been a captivating pursuit. The desire to create machines mimicking human actions, performing complex tasks, and even exhibiting artificial intelligence has driven countless innovations. However, real-world robots often fall short of their fictional counterparts in movies, television, and literature.
Bridging the Gap Between Science Fiction and Reality
Dennis Hong, a mechanical and aerospace engineering professor at UCLA and director of the Robotics and Mechanisms Laboratory (RoMeLa), is a prominent figure striving to close this gap. His diverse work includes lightweight, floating robots and powerful humanoid soccer-playing machines. Recently, Hong undertook a unique project, creating a real-life version of Cosmo, the robot from the Netflix movie “The Electric State.”
From Star Wars to Robotics: The Spark of Inspiration
Hong’s passion for robotics ignited at age seven after watching “Star Wars: Episode IV.” The film’s robots, C-3PO and R2-D2, captivated him, inspiring his lifelong dream of becoming a robot scientist. This early influence underscores the power of science fiction to inspire real-world scientific pursuits. Star Wars has significantly impacted robotics and other fields, inspiring countless engineers and scientists.
From Research Lab to Hollywood: Bridging the Divide
At RoMeLa, Hong’s team has developed a wide array of robots, including climbing, jumping, rolling, and even amoeba-mimicking robots. Their expertise extends to humanoid robots designed for complex tasks and human interaction.
Despite advancements in robotics, Hong recognized a disconnect between real-world robots and entertainment industry expectations. Filmmakers often favored CGI and green screen technology over physical robots. However, Hong saw value in creating tangible robots that could interact with audiences, enhancing realism in science fiction. This vision led him to collaborate with the Russo brothers on “The Electric State,” a film adaptation of a graphic novel.
Building Cosmo: A Unique Set of Challenges
Building a real-life Cosmo presented numerous challenges. Cosmo’s design prioritized aesthetics over practicality. Its large head and oversized boots made stable walking difficult, while its small body posed a packaging challenge for the necessary components. The tight eight-month deadline further complicated the project. This required a shift in focus from efficiency and functionality to capturing the character’s personality and expressions.
The BEAR Actuator: Mimicking Life-Like Movement
To achieve lifelike movement, Hong’s team developed the BEAR actuator (Back-Derivable Electromagnetic Actuators for Robots). Unlike stiff servo actuators, BEAR actuators are compliant, enabling natural and responsive movements, mimicking muscle function. This breakthrough allowed Cosmo to move with fluidity and expressiveness, and its applications extend beyond entertainment, potentially impacting assistive robotics and rehabilitation devices.
Cosmo’s Debut: From Premiere to Comic Con
Cosmo’s unveiling at “The Electric State” premiere was a resounding success, captivating audiences with its charm and lifelike movements. Cosmo subsequently traveled to comic cons and other events, further immersing fans in the film’s world. This success highlights the potential for robots in entertainment, offering immersive experiences beyond visual effects.
Humanoid Robots: A Reflection of Ourselves
Beyond Cosmo, Hong’s research explores practical humanoid robots. He argues that the human form is crucial for robots to interact effectively with human environments, using tools and navigating spaces designed for human dimensions. Humanoid robots can also undertake dangerous or difficult tasks, like disaster relief. Hong’s team developed THOR (Tactical Hazardous Operations Robot) specifically for such operations.
The Future of Robotics: A Blend of AI and Human Ingenuity
AI is increasingly crucial in robotics, enabling robots to learn, adapt, and make decisions. However, AI integration faces challenges, particularly the scarcity of data on robot motion, impact, and friction, hindering the training of AI algorithms for complex robotic systems. Despite these challenges, the development of large action models, analogous to large language models, holds promise for significant advancements in robot autonomy.
Robotics: A Force for Good
Hong views robotics as a force for good, designed to perform tasks humans cannot, should not, or do not want to do. Cosmo exemplifies this philosophy, demonstrating the potential of robots to enrich our lives in unexpected ways. Whether performing essential tasks or providing entertainment, robots can positively impact society.
The creation of the real-life Cosmo exemplifies the ingenuity and creativity in robotics research. By bridging science fiction and reality, Hong and his team have not only brought a beloved character to life but also advanced robotics technology. As AI progresses and our understanding of robotics deepens, we can anticipate further remarkable advancements, transforming how we live, work, and interact with the world.
