The world’s first full-size, purely electric running robot, Tiangong from China, has gone open source. Tiangong, developed by the state-backed Beijing Humanoid Robot Innovation Center, is a versatile humanoid robot capable of maintaining a steady speed of 3.73 miles per hour (6 kilometers per hour). The open-source project includes two versions of the humanoid robot, “Tiangong 1.0 LITE” and “Tiangong Pro,” with software and structural design documents already available.
