Which Servos/encoders do I have?

This tutorial supports the original ActivityBot Robot Kit (#32500) and the ActivityBot 360° Robot Kit (#32600). What's the difference?

Original ActivityBot Robot Kit (#32500)

This kit has HIgh Speed Continous Rotation Servos + External Encoders.  The servo has a white-red-black 3-wire cable.

Look for instructions mentioning "external encoders."

ActivityBot 360° Robot Kit (#32600)

This kit as Parallax Feedback 360° High Speed Servos.  This servo has a white-red-black 3-wire cable, and a separate yellow wire for sending feedback signals.  It does not use external encoders, as these servos have encoder sensors built right inside the case. 

Look for instructions mentioning "Feedback 360° servos."

Other Hardware

You will use these pieces during the hardware assembly.

Save for Later
