BALLU, the Buoyancy Assisted Lightweight Legged Unit, is a unique legged robot with a helium balloon body and articulated legs \fig{fig:fig1}. Since it is buoyant-assisted, BALLU is inherently stable, never falling over, while being able to walk, jump, and interact safely with people. The BALLU art installation builds on this playful platform to express fluidity, serendipity, and connection. It transforms robotic motion into an artistic visual and acoustic experience, merging technology and creativity into a dynamic, interactive display. This exhibition intentionally does not have a physical boundary for the robots, emphasizing the harmony of the technologies and humanity. This work significantly extends BALLU's existing permanent exhibition in the Seoul Robotics & Artificial Intelligence Museum, Seoul RAIM (https://anc.masilwide.com/2261), emphasizing the harmony of robotics and humanity through visual, acoustic, and physical expression.

The National Museum of Emerging Science and Innovation has made "aging" a centerpiece of its new permanent exhibitions that opened to the public on Wednesday. The museum in Tokyo's Odaiba district, popularly known as Miraikan, has completed work on four new permanent exhibitions, all of which are in line with its vision to help visitors confront various social issues and find ideas on how to overcome them, Miraikan CEO Chieko Asakawa told reporters Tuesday. In addition to the exhibition devoted to "aging," there are two new exhibitions that let people experience life with "robots," and one that showcases "planetary crisis," brought on by climate change and other global issues. "Aging is a rare topic to be handled by a science museum, but we have worked hard on creating an exhibit on this theme, thinking it's important for Japan," said Asakawa, a former IBM engineer and accessibility technology expert who assumed the current role at the museum in April 2021. "We want to convey the message that Japan's superaging society can lead the world by making the best of technologies and social systems to deal with aging."
