Take a look at that thread. If you take a look at the 2nd image on the page (titled "Image 2 of 4"), you can see a black motor on the arm joint (2nd stage of the arm). Looks like they are probabaly using the Denso Window motors, because they would need 2. It can't be the Bosch Van Door motor because we only get to use 1 of them. The CIM motors would be overkill for this application. It makes sense that the window motors would be used because of their worm gear and you wouldn't want the secondary arm to lift up if you want to transfer weight.
If you look at the rear of the robot in that picture, you can see another black motor (unless that's poorly blended background). My guess is that this would be the Van Door Motor and it controls the wings together. This would be practical, because it can be backdriven and you wouldn't want to damage the wings. It also has lots of torque.
The 3rd stage looks as if it swings freely.
