China is all prepped to host the world’s first half marathon with 12,000 human participants and bipedal robots—or humanoid robots that can walk on two legs, similar to humans—from over 20 companies. Scheduled for April, the participants of the race compete across a 21-km course in Beijing’s Economic-Technological Development Area, also known as E-Town. This event is being hailed as a bold testament about the future of the tech world and of human-robot collaboration and its endless possibilities. The event will feature a diverse line-up of robotic participants, including humanoid robots, drones, and wheeled machines, each designed to tackle the 42-km challenge in their own unique way.
