Hardware · `UR18g-950` · verification: source checked

The UR18g-950 is a six-axis collaborative robot arm from Universal Robots' Generation 7 g-Series, with an 18 kg payload and a 950 mm reach. It is IP65 rated, reaches a maximum TCP speed of 4 m/s, and repeats poses within ±0.05 mm per ISO 9283. An integrated force-torque sensor and power, I/O and Ethernet connectors at the tool flange let cameras, sensors and end effectors be connected without external cabling.
