Foundation Phantom MK-1

Reported five-fingered hands, 19 upper-body degrees of freedom, 20 kg payload, and cycloidal actuators up to 160 Nm. Foundation told Reuters the MK1 helped build more than 24,000 cars in 2025. Mezha reports the MK-1 arms and wrists remain immobile, conflicting with the five-fingered hands description.

TNW describes an LLM-driven autonomy stack blending independent operation with supervised teleoperation. Mezha describes Cortex AI with reasoning and world models. The company says human operators retain final authority over lethal decisions but aims to reduce teleoperation needs over time.

Walking speed listed at 1.7 m/s. Humanoid Press directory lists capabilities including obstacle avoidance, stand-up-from-fall, running 100 m, walking stairs, and jumping and landing, but Mezha reports the MK-1 cannot rise after a fall. No independent mobility metric or demo transcript was found.

Camera-first perception with eight cameras, no LiDAR. Mezha says helmet cameras provide 360-degree view and Cortex's world model analyzes the environment. No camera resolution, FOV, or perception benchmark published.

The LLM pipeline translates natural language commands into motion, per TNW and The Robotic Life. Foundation's stated policy is human-in-the-loop for lethal decisions. No conversational or instruction-following reliability metric was found.

The Robotic Life lists 4 hours battery life. Mezha reports MK-1 has no battery and is not dust- or water-resistant. TNW says MK-2 adds larger battery packs and waterproofing. No independent reliability tests or failure-rate data were found.

Human-sized (175 cm, about 80 kg) biped. Mezha reports it is not dust- and water-resistant and cannot rise after a fall, indicating limited ruggedness for field use. No full-robot safety certification was found.
