Product description
Integrated Cycloidal Joint Module with Direct Drive and Precision Alignment This next-generation joint module combines lightweight design, high burst power, impact resistance, ultra-high precision with low backdrivability, high-frequency communication, and superior integration in a single unit. Equipped with an advanced inertia and damping compensation algorithm, it withstands instantaneous overloads exceeding 5 times the rated torque while achieving repeat positioning accuracy better than 1 arcminute. The module integrates drive controller, reducer, motor, and dual encoders into one compact unit.Featuring a reducer with a built-in cross-roller bearing, its modular design ensures easy maintenance, upgrades, and seamless scalability. This greatly enhances robot expandability and customization potential. Powered by a self-developed hybrid communication architecture of Ethernet +CANFD, the system supports bandwidths exceeding 100 Mbps and delivers hard real-time communication at over 1 kHz, making it an ideal solution for high-frequency, dynamic robotic applications.
