TOKYO, Jan 29 (News On Japan) - A Japanese-developed humanoid AI robot known as “cinnamon 1,” standing about 170 centimeters tall and weighing roughly 70 kilograms, has drawn attention as a next-generation “physical AI” robot designed to understand real-world environments and act within them. This year is increasingly being described as the starting point for physical AI, and cinnamon 1 is being positioned as a potential challenger to the dominance of the United States and China in robot AI development. Cinnamon 1 is a full-scale humanoid robot built to perform practical work rather than entertainment-focused tasks. While its outer body is manufactured overseas, its core intelligence is powered by AI developed in-house by a Japanese robotics company. This gives cinnamon 1 a practical advantage over AI robots that rely solely on voice interaction.
