Flexible and user-friendly robots. The UR-3, UR-5, and UR-10 by Universal Robots are a lightweight, 6-Axis robot arm. Universal Robots comply with the RIA safety specification R15.06 – This simply means that, for most cases, there is no requirement for safety guarding. Programming is done intuitively: simply grab the robot arm to the desired positions and save each waypoint. The robot is controlled from a handy, touch-sensitive screen with a graphic user interface.
