Notes

  • Booster sells K1 in three editions — Geek, Education, Professional — shown side by side on one product page. Height (~95cm), weight (~19.5kg) and degrees of freedom (22) are identical across all three. Compute, battery and runtime differ per edition: compute 48/117/200 TOPS; battery 2Ah Geek vs 5Ah Education/Professional; runtime while walking at 0.4 m/s 30min Geek vs 80min Education/Professional.
  • Total DoF (22) is broken down on the page as: legs 6 DoF per leg, arms 4 DoF per arm, head 2 DoF (6x2 + 4x2 + 2 = 22).
  • Booster's own K1 page offers all three editions for sale through the manufacturer's online store; no price is shown.
  • Booster describes K1 as "RoboCup 2025 KidSize champion & runner-up" and cites a customer case with the HTWK Team (Germany) and a stage-performance case at the "2025 World Humanoid Robotics Games"; these are competition and demonstration results, not a named industry category.
  • Booster Robotics' press release of 30 October 2025 (PR Newswire, reprinted by Tirto) announces the official launch of Booster K1 at its 2025 ecosystem conference in Beijing.
