The DexCap is a high-precision exoskeleton teleoperation platform. It employs a lightweight, heterogeneous exoskeleton architecture integrated with a high-density sensor network (9 DoF per arm, 21 DoF per hand, 5 DoF for waist), achieving millimeter-level motion capture and kilohertz-range responsiveness (>1000 Hz). The system supports multi-modal interaction, including five-level tactile feedback and millisecond-level low-latency communication, ensuring precise 1:1 action mapping. Featuring a modular design, it is compatible with mainstream robotic arm protocols and Windows/Linux operating systems. This makes it suitable for remote operations in special environments, VR interaction, and scientific R&D. With ultra-long battery life offering up to 8 hours of operation on a single charge, it supports all-day, long-duration operations. The DexCap provides a comprehensive, high-fidelity data acquisition solution for fields such as human motion data collection and robotics.
