Robot arm & cobot joints
High-ratio joint modules (harmonic, cycloid and high-reduction planetary) for arms that need stiffness, precision and holding torque.
- High ratios give stiffness and holding torque but are hard to backdrive.
- Check whether a brake is available for joints that hold a load at rest.
