Z1 .
6-DOF precision arm for mobile manipulation, research and automation.
Research-grade machinery for trained adult operators, not a toy. Read the Product Safety Notice before you order.
±0.1 mm Repeatability
Six harmonic-drive joints give the Z1 industrial-grade repeatability of about ±0.1 mm across a 740 mm reach — precise enough for grasping and insertion research, visual servoing, light assembly and repeatable sample handling. Its published kinematics and URDF models support calibration work and reproducible experiments.
