Building an automatic entrance door

Let's build a door by following the building instructions given next. This is what our door should eventually look like:

Figure 9.2

We'll proceed as follows:

1. Let's start our construction by taking two 1x10 bricks to make the base, as illustrated here:

   Figure 9.3

2. Then, take six connector pegs and connect them to the bricks, like so:

   Figure 9.4

3. Now, take two 1x16 bricks and connect them to each other, as follows:

   Figure 9.5

4. Then, take four 1x2 plates and connect them to both ends of the brick, as follows:

   Figure 9.6

5. Take two 1x2 bricks and connect them to the plates, like this:

   Figure 9.7

6. Now, mount this whole structure onto the blue bricks with connector pegs. Then, take two tubes with double holes and connect them with connector pegs, as illustrated here:

   Figure 9.8

7. Take two connector pegs and two 2M cross axles with snap, and connect them to the brick, as shown here:
