Overview

A record-chasing sprint quadruped from Zhejiang University's Center for X-Mechanics (XMECH) and Mirror Me, a Shanghai startup founded in May 2024 by ZJU professor Hongtao Wang and researcher Yongbin Jin. It was revealed as Black Panther 2.0 in January 2025. Mirror Me calls it Black Panther II, a CCTV show called it Black Panther 2.2 and the team's papers call it BP2. Springs at the knees, carbon-fiber shins inspired by jerboas and a gait built on Huygens' coupled-pendulum principle let a 36 kg robot reach sprint speeds. It follows a 10 kg Black Panther that ran 5 m/s in a 2022 Nature Machine Intelligence paper.

The early "100 m in under 10 seconds" headlines were an extrapolation from treadmill speed, not a measured run. In January 2025 it held about 10 m/s on a lab treadmill, with 10.4 m/s shown in a video. On July 6, 2025 it hit 10.3 m/s on a treadmill in Wuhan. The same day it ran 100 m on a track in 13.17 s from a standing start, peaking at 9.7 m/s. It later raced sprinter Noah Lyles for a MrBeast video and finished 100 m in 12.2 s. The team's September 2026 papers report 13.2 m/s on a treadmill, 11.65 m/s outdoors on concrete and a best 100 m of 11.67 s. The treadmill figure passes the 12.6 m/s record that Boston Dynamics' Cheetah set in 2012, though none of these runs is a certified record. The Guinness 100 m title belongs to its stablemate White Rhino at 16.33 s. Mirror Me's consumer Black Panther X is a separate 4 m/s kit it calls the legacy of this line, the closest thing to Black Panther 2.0 that anyone can buy.

Price and shipping

A research robot from Zhejiang University's Center for X-Mechanics and its spin-off Mirror Me. Mirror Me describes Black Panther II as a high-mobility quadruped for education and research, but no price, store or delivered unit has been found (checked October 2026). The company's only orderable quadruped is the slower Black Panther X kit.

Shipping: N/A. Not sold. Mirror Me lists no price or order option for Black Panther II and sells only its Black Panther X kit, which closed on Kickstarter in April 2026 (checked October 2026). Mirror Me ↗

LLM support	None · No LLM and no public SDK. Running is driven by learned locomotion policies built by the research team.
MuJoCo simulation	None found · Nothing public. The team's 2026 RA-L paper checks its policies in MuJoCo before running them on the robot, but no BP2 model has been released. arXiv 2609.13289 ↗
NVIDIA Isaac simulation	None found · Nothing public. The RA-L paper trains in Isaac Gym with 4,096 parallel environments, but no model or training code for BP2 has been released. arXiv 2609.13289 ↗
Gazebo simulation	None found · Nothing found. No URDF or robot description has been published. The lab's public IRRL code on GitHub covers the earlier 10 kg Black Panther, trained in RaiSim. GitHub (IRRL) ↗
