Product overview
About HighTorque Xiaopai
Xiaopai (小派) is HighTorque Robotics' Mini Pi plus, a small commercial biped for education, research and competitions. HighTorque uses both names in its official 2026 competition report. A founder interview describes the robot as mass-produced and says it uses swappable batteries.
The current official 22-DoF product page lists a height of 680 mm, weight of 15.15 kg including battery, maximum load of 10 kg and peak joint torque of 21 N·m. The 24 V removable battery is rated at 4,500 mAh and 97.2 Wh, with about 90 minutes charging and more than one hour of rated endurance. Official development documentation supports a public SDK and secondary development.
HighTorque's pages describe multiple configurations. A newer hardware reference describes a 27-DoF, roughly 75 cm and 13.84 kg configuration, while the international store text describes an older 26-DoF, 65 cm and 10.9 kg configuration. The structured specifications therefore follow the current 22-DoF product page and identify the conflict. The store lists Mini Pi plus at US$5,500; the founder separately quoted lower domestic starting prices for some configurations.
The founder said Xiaopai covered about 10 km in the 2026 humanoid robot half-marathon and reported a 12-hour internal continuous-running test with battery swaps. That test is not used as the per-charge runtime.
