Lesson 5: Designing with Gears

In the final lesson of this unit, students will retrieve a 3d printed "load" using their GoPiGo and their design skills.

1. Investigate: Gears

In lesson 4 we attached servo motors to our GoPiGo and had a lot of fun by creating moving parts with the rotating motion of a servo motor. In this lesson, we are going to explore how we can use 3d printed gears to make parts move in different ways. A set of gears working together is a "Gear Drive", where one gear is the driver and pushes the other gear which we call the driven gear.

The two types of gear sets we will explore in this lesson are:

1) Gear Train

2) Rack and Pinion
