Alternating Swinging Arms (Mechanisms) - Page 129, Build #170
Did I mention I like moving things? I especially like watching the gears move. So, this one was just perfect for today.
Parts we're going to use today:

Simple Rack-and-Pinion gears (Mechanisms) - Page 115, Build #155
This is what we're building today - Rack-and-pinion gears.
Have a great day!
Rack-and-pinion gears are used to change rotational movement (the yellow and gray gears with the rubber band going around it) to linear movement (the side-to-side movement going across the white pieces or racks). The steering system in cars is a good example of rack-and-pinion gears at work.
Parts I'm using today:
I'm making do with what I have. I'm pretty sure they'll work fine. If not, we'll just have to figure things out as we go.
Let's build:
1st design for the motor support.
In this state, it wasn't the white rack that moved from side-to-side, but the gears moving awkwardly.
So, I removed some support pieces, and stuck the motor on a bigger, anchoring piece. But this still moved things enough that the video didn't turn out very well. So, when I was recording the video, the gray platform had to be held down.
It was still neat to watch.
Here's a video. Enjoy!

Scissor Lift 1 (Mechanisms) - Page 212, Build #237
I love things that move, and we're making this Scissor Lift today.
Just like the previous Claw Gripper, I was trying to build a vehicle and put this on top with Mindstorm controlling it, but I didn't have enough time. So, I guess I'm going to have to build this in stages, too.
I had a lot of fun building this. I hope you get a chance to build it, and see it work. I like watching the worm gear work as the Scissor Lift goes up and down.
Enjoy!
PS - updated with videos!
