Core Skill: Robotics
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Extending the Shaft of the Microgear Motor
If you are looking for a way to extend the microgear motor's shaft to add an encoder, feel free to use the Shaft Coupler - 1/4" to 3mm [ https://www.sparkfun.com/products/12412 ]. You would just need to find a shaft length that is suitable for your project. Here's an example from ServoCity using a shaft coupler with a micro gearmotor => [ https://www.servocity.com/media/catalog/product/cache/1/image/438x280/602f0fa2c1f0d1ba5e241f914e856ff9/c/o/coupler_on_gearmotor_with_shafting.jpg ].
