This upgrade kit has been developed together with the HSP@IIT research line as an optional plug-in support to improve iCub perception and facilitate it in grasping tasks iCub. For reference, see also the page design holder realsense.
The holder has been designed to be compatible with the following RealSense models:
|INTEL_REALSENSE_D415||Intel Realsense D415, range from 0.3 to 10m, FOV 70 de||13038|
|INTEL_REALSENSE_D435i||Intel Realsense D435i with IMU, range from 0.2 to 10m, FOV 90 de i||14567|
|INTEL_REALSENSE_D405||Intel RealSense D405 with IMU, range from 7 cm to 50 cm, FOV 87°×58°||17231|
Not all the RealSense cameras have the same interface, some of them connect by using a different cable.

The RealSense holder can be mounted on the top of iCub head by replacing two side screws fixing the face cover, and in the kit are included and USB Type-C cable, screws and cable ties. The kit does NOT include the RealSense. It is recommended to replace the short cable included in the RealSense retail package with the longer one provided with the upgrade kit.
The following instructions are provided for assembling the D435i model of RealSense camera.
Perform the assembly sequence as shown in the following images.
- First step, remove the two screws V4-12--_-_U5933_C from the side of the face cover as can be seen in the image. Set them aside, just in case you want to successively unmount the RealSense holder.
- Second step, fix the holder IG_027_P_010 with the respective screws V4-16--_-_ISO7045_CZ as shown in the image, and fix the hook to the backward cover air vents.
- Third step, fix the chosen RealSense model to the holder usign the screws V3-8--_-_U5933_C. At this point is possible to plug the USB Type-C cable cod. 15365 and use the cable ties cod. 531 to fix it around the head.
As mentioned above, the RealSense D405 uses a different cable too.
