KIT_004 iCub upper arm covers preventing skin breakage
The 3D taxels points are not yet available for both
right_arm limbs of iCub robots mounting this UKit (iCub HW version 2.7). For this reason,
skinManager may not work as expected. This information will be added in the near future. Instead, the 2D positions of the new patches have been defined such that
iCubSkinGui can work just fine.

In previous revisions of the covers, the mini cards were organized in the shape of hexagons. This largely caused the skin patch PCB to flex and break, because the patches took the high curvature of the cover (see image).
To solve this problem, we reduced the number of PCBs by arranging a strip with 5 PCBs (skin patch) on the flat surface of the cover. (see image)
First of all, it must be said that the electronic part of the upper arm covers is already supplied, that is, the MTB4 cards and the hexagon shape (skin) are mounted, glued and connected together.
Before starting assembly, check the orientation of the covers.
Assembly sequence :
Perform the assembly sequence as shown in the image, keep in mind that the sequence is the same for both upper arms (Right and left)
First step push the cover (RC_IIT_017_P_023) inwards so as to align the attachment holes, both positions (TOP and BOTTOM), as can be seen in the image. -
Second and third step, fix the cover using the respective screws as shown in the image. This applies to both positions TOP and BOTTOM.
- Fourth step, close the covers of the upper arm by pushing the Lover cover inwards in order to align the attachment holes. After that fix the covers with the respective lives as shown in the pictures. This applies to both positions TOP and BOTTOM.
