Disney Research has unveiled a groundbreaking bipedal robot that can navigate the ramps, stairs, and other uneven terrain common to theme parks.
“The legged robot has achieved impressive results in dynamic locomotion on challenging unstructured terrain,” the team said.
While legged robots have proven adept at navigating difficult terrain, designing and controlling them for entertainment purposes is an entirely different story, the researchers stressed.
To captivate human audiences, robots need more than agility and balance: they need to be expressive, engaging and evoke emotion in the viewer.
“Our goal is to bring expressive and dynamic movement to bipedal robotic characters and explore the intersection of legged robot design, control, and character animation,” the team added.
Disney’s innovative creations seamlessly blend expressive, artistic movement with robust, dynamic maneuverability, marking a major advancement in entertainment robotics.
Technological advances
The robot, which is largely 3D printed, was developed in less than a year by a team led by research scientist Moritz Becher at Disney Research in Zurich.
The technological innovation associated with this bipedal robot is remarkable: its character-driven mechanical design prioritizes expressive movement, allowing the robot to convey a wide range of emotions and connect with audiences in a more meaningful way.
Moreover, the reinforcement learning-based control system enables the robot to smoothly and naturally execute artistic movements in response to command signals.
Meanwhile, an advanced animation engine generates these signals by seamlessly blending multiple animation sources, resulting in dynamic, realistic movement.
Additionally, an intuitive operator interface allows operators to control the robot in real time, enabling live performances and interactive experiences.
Creative intent and collaboration
“We introduce new robotic characters with mechanical designs driven primarily by creative intent and simplicity, rather than functional requirements,” Disney Research said.
What is noteworthy is that the robot’s expressiveness, achieved by movements such as swinging its antennae and tilting its head, does not detract from its excellent walking and balancing abilities.
This was made possible through close collaboration between roboticists and animators, ensuring the robot’s movements were expressive and stable.
This new bipedal robot represents a major step forward in entertainment robotics.
Beyond anthropomorphism and animalization
The integration of expressive movements and agile locomotion offers the potential to enhance human-robot interaction in a variety of contexts, not just within theme parks.
Disney’s expressive bipedal robot offers a glimpse into the future of entertainment robotics, where robots can seamlessly integrate into different environments and engage audiences in new and exciting ways.
As technology continues to advance, we can expect to see even more sophisticated and expressive robots in the future.
“Our research enables the creation of expressive robot characters that go beyond typical anthropomorphic or animalistic forms, paving the way for more general and fantastical robot characters,” the team concluded.
