Product Overview

Overview

KAI Hand is a next-generation, highly dexterous and anthropomorphic robotic hand developed by Kinetix AI, featuring a hybrid direct-driven and tendon-driven actuation architecture. It offers passive compliance, thermally balanced design, and modular construction. Engineered specifically for embodied intelligence, it delivers manipulation capabilities approaching those of the human hand.

Core Capabilities

• High DoF and High Anthropomorphism： Human-like kinematics simplify motion retargeting and human-to-robot data transfer.
• Passive Compliance Design: Superior Operational Experience，Reliable Under Collision
• Thermal-balanced design: Self-locking transmission supports sustained grasps while reducing heat and extending actuator life.
• Modular design: User-replaceable fingers simplify maintenance and reduce downtime.
• Multimodal Perception: An integrated vision and tactile sensing system supports open-source datasets and enables more informed decision-making.
