K-Scale K-Bot vs Tiangong

K-Scale K-Bot was an open-source humanoid robot from K-Scale Labs (Palo Alto) with reported specs of 1.4 m height, 34 kg weight, 10 kg payload, 4-hour battery life, modular compute, swappable end effectors, and a starting price of $10,999. It targeted developers with an open-source RL library and sim2real pipeline. The company shipped a small number of Founder's Edition units and demonstrated low-latency teleoperation, but canceled all pre-orders and refunded deposits in November 2025 after failing to raise funding, then open-sourced hardware (CERN-OHL-S-2.0) and software (MIT). No autonomous operation, DoF, walking speed, or independent benchmarks were found

Tiangong is the first full-size biped from the Beijing Humanoid Robot Innovation Center (X-Humanoid), publicly shown on 2024-04-27 as an open, research-oriented platform: 163 cm, 43 kg, fully electric, with a 48 V/15 Ah pack, 3D vision sensors, a high-precision IMU, six-axis force sensors and a claimed 550 trillion operations per second of onboard compute; a directory records 20 total DoF for the launch configuration. The public evidence is essentially locomotion — a claimed stable 6 km/h run and slope/stair traversal described as 'blind' — with no manipulation (the launch robot is reported to lack human-like hands), no task autonomy, no endurance or reliability data and no human-interaction evidence. It is research-only and not for sale, and has been superseded by later Tiangong variants (1.1 PRO, 1.2 MAX, Walker, Ultra, Omni, 2.0, 3.0) whose records must not be credited to this robot
