What is URCap?

UR's official plugin platform. Ubiros on board.

URCap is Universal Robots' official plugin platform for integrating third-party hardware directly into the UR cobot ecosystem. Once installed, your Ubiros gripper appears as a native device inside Polyscope — with visual program nodes, force and position control, and full grip feedback, all without writing a line of code.

The plugin supports the full UR e-Series lineup and uses the same 24 V DC power and data interface your robot already provides. No external controller boxes, no compressed air, no infrastructure to add.
