R2D2, Part 2

 The second parts bag of the R2D2 set consists of the components to build up the droid's central 'foot'. 

There is nothing exceptionally difficult in the assembly at this stage, as all are standard plates, bricks, and slopes, with added small detail elements.

Once the foot itself is done, a long Technic beam assembly is built and attached. 

This beam then slides inside the Technic frame built from bag 1, interacting with the existing components to give the necessary forward/backward motion of Artoo's foot.

The only difficulties that could be encountered here are the proper insertion of the various Technic 'stop' pins on the beam, and orientation of moving parts. The instruction illustrations are quite crowded at this point, so the builder must pay extra attention to them.

Here is a pic of the completed assemby:
