Mantis Standard

Blue Worm

China

Mantis Standard, nicknamed Xiaobai, is Blue Worm's modular wheeled humanoid, launched on 14 September 2026 from 9,800 yuan. It stands 1.4 metres - the company sized it against a middle-school student - and carries 22 degrees of freedom, with 7 DoF in each arm, a 7 kg rated payload per arm and repeat positioning accuracy of plus or minus 1 mm. The base is omnidirectional and wheeled rather than legged: it reaches 3 m/s, turns through a full 360 degrees and carries a lidar for navigation, which the company argues is the right trade for work that is mostly upper-limb manipulation, where wheels are more stable, more reliable and cheaper than legs. The head is a three-axis gimbal carrying a 4K 60 fps stereo camera pair, the waist lifts through 550 mm at 200 mm/s, battery life is three hours and control latency is under 10 ms. Its central idea is one brain, many forms: a single self-developed BW-Brain runs the Wormhole foundation model series on a VLA plus DRL plus WAM framework, so a detached arm has full sensing and decision-making on its own, the base works alone as a mobile handler, an arm plus a base can grasp and carry at once, and the assembled humanoid uses exactly the same intelligence. Every module joins through quick-fit interfaces that complete the mechanical and electrical connection in one action, so buyers can start with only the modules their scenario needs and recombine later instead of replacing the whole machine. Teleoperation covers vision, hearing, speech, force and control with VR support, and doubles as the data collection process, while the developer toolchain spans Isaac Sim and Genesis simulation, a ROS 2 interface, the BlueWorm SDK and LeRobot compatibility with pi-0.5, ACT and SmolVLA.
