Product overview
About Noetix Bumi
Bumi is Noetix Robotics' compact bipedal platform for education, entertainment and home experimentation. The manufacturer's current specification lists a 98 cm height, an approximate 17 kg weight including the battery and 21 active degrees of freedom: nine in the upper body and twelve in the lower body. It also lists a top speed of 0.5 m/s and maximum joint-module torque of 70 Nm. These current official figures replace the smaller 94 cm and 12 kg measurements reported during the 2025 pre-sale period.
The robot uses a quick-release 48 V, 5.1 Ah battery and is rated for up to three hours of operation. Multiplying the published voltage and capacity gives about 0.245 kWh. Noetix publishes C++ and Python SDKs for high- and low-level control over DDS, making Bumi suitable for programming and robotics instruction as well as demonstrations.
Press coverage reported a CNY 9,998 launch pre-sale price and 523 JD.com reservations by late October 2025. Noetix later publicized an on-site Bumi delivery at AWE in March 2026, while press coverage reported first-user deliveries that month. The current official product page does not publish a retail price, so the recorded amount remains the reported launch pre-sale price rather than a verified current list price.
