| Robot-version             | Minimum Software Version |
| ------------------------- | ------------------------ |
| **CB-Series (>= CB 3.0)** | **3.11**                 |

To install the URCap, the supplied USB stick must be inserted into a USB port of the UR\
(e.g. on the teach pendant). Via the main menu in the upper right corner, labeled with the hamburger button, the robobrain® URCap can be added using the "***+***" button in the\ <mark style="color:blue;">Settings -> System -> URCaps</mark> area. Afterwards a restart of the robot is necessary.

After successful installation, the system in use needs to be configured. Via the Installation tab in the upper bar of the UR user interface, you can access the settings area of all installed URCaps. Under the **Configuration** drop-down menu in the robobrain® URCap, you can enter the static IP address of the robobrain® you want to communicate with and then test the connection. The settings must be saved via the **Save** button. After these steps, you can leave the installation area.
