Remote control: Same Ethernet Python SDK as xArm: XArmAPI('<ip>') from a laptop, or ROS 2 on a Linux host.

Overview

UFACTORY's industrial-grade arm, with harmonic drives and 17-bit encoders giving ±0.02 mm repeatability, a UR5e-class 850 mm reach and 5 kg payload at roughly a third of typical cobot pricing. It keeps the open SDK of the xArm family, which makes it a budget stand-in for UR-style arms in research and automation in small shops.
