I will agree with Andy - I see 7 joints in each arm. BTW I saw them in Hanouver Messe in spring and ABB disappointed me a little bit - the tool at the end of wrist _did move_ a little, when they did the moves in 00:22 - 00:24, so kinematics are not perfect. Genserkins definitely could handle such an arm, but I do not see a way to repeat the same moves in 00:22 - 00:24, because the tool is not supposed to move. I suspect that code for these arms is written in joint coordinates, not cartesian coordinates. And that means using expensive CAM programs with postprocessors, which also cost a lot. Other than that the design is incredibly agile and arm can manipulate in very space-limited conditions.
