Price and availability
from evidence packWhat the K-Scale K-Bot can do
evidence by capability dimensionK-Bot is described with adaptable end effectors for different tasks; a company engineer on Hacker News says hands are easily swappable using a camera lens style mount. No dexterity demo or success rates were found.
Initial release was expected to have basic locomotion, balance control, voice commands, and app-based control using pre-defined command sets; full autonomy was projected for June 2028 with less than 1 human intervention per day. A low-latency teleoperation demo was reported, which is explicitly teleoperated, not autonomous.
The robot was expected to have basic locomotion and balance control at initial release. No walking speed, fall rate, or whole-body control demo was found.
The robot is equipped with RGB camera, stereo vision, ultra-wide FOV camera, far-field microphones, and stereo speakers. No perception benchmark or scene understanding demo was found.
Initial release expected voice commands and app-based control using pre-defined command sets. The robot includes far-field microphones and stereo speakers.
Battery life is listed as 4 hours. No operating hours, failure rates, or reliability metrics were found.
The robot is 1.4 m tall and 34 kg with a 10 kg payload, intended for household chores like mopping and preparing bread in toasters. No safety certification or home deployment evidence was found.
What is proven
source-backed highlights- Open-source RL library and sim2real pipeline released to developers (source 003).
- Modular compute and swappable end effectors (source 001).
- Hardware released under CERN-OHL-S-2.0 and software under MIT after shutdown (source 002).
- Low price point for a humanoid, even if ultimately not available (source 001).
Caveats
read before you trust a demo- Pre-orders canceled and refunded; no active purchase path. The shop URL may be inactive
- No independent benchmark, autonomy demo, or reliability data.
- No total DoF, hand DoF, battery capacity, walking speed, or compute model.
- Only a media report of Founder's Edition shipping; no customer names or unit counts.
About the K-Scale K-Bot
summary from sourced evidenceK-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
