Need help to obtain link masses of the ABB YuMi


we are two students using a ABB YuMi for our master thesis. For our last experiments we are in need of the masses of YuMi's links. Having searched "Product Manual - IRB 14000" , "Product Specifications - IRB 14000" and "Operating Manual - IRB 14000"  in addition to internet searches,  we are unable to find this information. Any help obtaining this information would be greatly appreciated.
