KaiBot
KAI
Product Overview
**World's Highest-DOF Humanoid Robot** Understanding the world means enabling the robot not only to perceive its current environment but also to predict upcoming environmental changes — this is the KAI World Model. If the World Model addresses understanding the world, then first-person datasets address learning the world. KAI’s approach is to observe and interact with the world from a human perspective and through human actions, thereby gaining experience that is closer to real-world scenarios. Chaowei Power has developed a large‑scale proprietary data‑capture terminal, the KAI Halo. This lightweight headband‑shaped device features “one chip, eight cameras,” enabling one‑stop collection of human‑world data. It can record first‑person perspective videos as well as reconstruct human poses and scene point clouds. Because the device is light enough to be worn naturally during daily activities, the data collection process does not rely on scripted arrangements, and the data is much closer to real‑world scenes. Compared to deliberately designed motion sequences, this type of data captures a wider variety of movements and is more suitable for humanoid robot training. In terms of physique, KaiBot stands 173 cm tall, weighs 70 kg, and has a head‑to‑body ratio of 1:8.5. Its overall body shape and mass distribution are close to those of an adult human, ensuring stability while resembling human proportions and center‑of‑mass distribution. In terms of physical capabilities, KaiBot has 115 degrees of freedom (DoF), giving it a shoulder lift range of –20° to 0°, a shoulder wrap range of –15° to 0°, a neck range of –15° to 50°, and a waist range of –15° to 75°. These ranges closely match the whole‑body motion space of a human and approximate how human limbs naturally move in complex environments. Additionally, KaiBot is equipped with a dexterous hand featuring 36 DoF per hand, consisting of 22 actively controlled DoF and 14 compliant DoF. This allows not only fine manipulation such as grasping and pinching but also impact buffering, resulting in safer and more natural interaction characteristics. In terms of strength, KaiBot is powered by a 1.7 kWh semi‑solid battery, supporting approximately 3 hours of dual‑arm manipulation tasks. At the same time, its custom compliant actuators not only help the robot achieve motion smoothness closer to that of a human but also give it a dual‑arm payload of nearly 20 kg, balancing interaction friendliness with operational capability. In terms of sensory perception, KaiBot is equipped with a full‑body tactile skin system featuring 18,000 contact points. In theory, it can perceive and respond to gentle touches as light as 0.1 N. This tactile system enables the humanoid robot to establish higher‑quality feedback loops in close‑quarters collaboration and companion interaction within real‑world scenarios.
