If your Propeller ActivityBot belongs to a school, it may have been put together already.
Replacement Parts: Most of the pieces in the kit are available for purchase individually online from www.parallax.com [2]. Or, email sales@parallax.com or call 888-512-1024.
This tutorial supports the original ActivityBot Robot Kit (#32500) and the ActivityBot 360° Robot Kit (#32600). What's the difference?
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."
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."
You will use these pieces during the hardware assembly.
These pieces won't be needed for the hardware assembly, so you can set them aside and save them for later activities.
Have Feedback 360° Servos? If yes, skip this step.
Go to Step 2 - Prepare the Tires [3].
These parts are bagged together as the ActivityBot Encoder Kit. Save the resistors, you will need them later for Electrical Connections.
Parts needed for this step:
Asemble the right and left encoders to be mirror images of each other.
For all ActivityBot robot kits.

Prepared chassis:
For all ActivityBot robots, whether you have HIgh Speed Servos with X-shaped horns (#900-00025) or Feedback 360° servos with O-shaped horns (#900-00360).
For all ActivityBot robots, but read carefully. Directions are slighty different for robots with external encoders.
Parts for this step:
Lock-nuts have white Nylon inserts that make a tight grip on screws so they don't loosen easily with vibration. But, they take a little more force to install.
As you work, press the closed end of the little black wrench over each lock-nut to hold it in place while attaching the screws.

Parts for this step:
CAUTION - the ends of the cotter pin may be sharp! If you have needle-nose pliers, you can bend the cotter pin ends into a circle to tuck away the points. But be aware that this makes the cotter pin more difficult to remove in the future if you ever want to do that.
This step is for all ActivityBot robots.
