Hi! Here are the instructions to the multiple arm lift.
Here's a video: http://www.youtube.com/watch?v=0IF4ZdzzzVs
This isn't the exact same as the video though, because I forgot to make the instructable when I made this.
Step 1: That section there... ?
Nah, this has a name. This part holds the ball dispenser, I just can't summarise it into a title.
Step 2: Extra safety to that part
This section fits on top of what's been built so far.
It should give a clear view where the arm comes to.
Step 3: The ball dispenser
As the name explains.
Step 4: Adding the dispenser
Again, self explanatory.
Step 5: Roll into dispenser part 1
This section will hold the path coming into the dispenser.
Step 6: Roll into dispenser part 2
Here's the actual track the ball goes on.
Step 7: Putting that part together
Here's the side bit attached to the dispensor bit with the path on it.
Step 8: Adding 4 red rods
Just get 4 red rods and add them like in the picture.
Step 9: The real part beggins!
It's just a hexagonal prism, only with a bumper at the front. I'll stress it in the picture.Y
Step 10: Adding it in
This fits in to the four red rods. All together it didn't fit into the picture, so that's why it's split into 2 steps.
Step 11: Layer 1
Layer 1 excluding the main base. There should be a missing blue rod (that's where the lower arm comes).
Step 12: Sticking it on
Now stick that layer to the rest of the lift.
Step 13: Layer 2
Now the second layer. This time there are 2 missing red rods. They get in the way of the crankshaft.
You might realise extra parts sticking out, they're to hold the motor.
Step 14: Adding the second layer.
The bit on the side should help with the orientation.
Step 15: Layer 3
This is layer 3, as the name says. Like layer 1, it's missing a blue rod.
Step 16: Adding layer 3
Sorry about the photo, the side bit should clear things up.
Step 17: The motor
This part is for the motor (of coarse).
Step 18: Adding the motor
This motor attaches to the side part.
Step 19: Motor's rod
The picture is of the rod that clips into the motor with gaps where the motor, white connector and the orange connector go.
Step 20: Adding that rod with spacers
Here is a demonstration where the rod goes.
Step 21: The crankshaft
This is a doulbe crankshaft which is why there's no room for two extra red rods. (an excuse to save pieces).
