Prepare the External Encoders

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:

• (2) Sharp infrared sensor (#350-00038)
• (2) Cable for encoders (#805-28107)
• (2) Encoder bracket (#721-00031)

Asemble the right and left encoders to be mirror images of each other.

• Place an encoder sensor on each encoder plate, with the cable socket facing the hook end.
• Secure each sensor to its plate with a black 1/4" screw.  It will not need a nut to secure it - the plastic plate will hold it in place.
• Push the white plug end of an encoder cable into each sensor's socket. It should only insert one way; make sure it seats all the way in.
