Pololu Zumo Chassis User’s Guide © 2001–2019 Pololu Corporation 1. Introduction Attention: If you are assembling a Zumo Robot for Arduino using the Zumo Shield for Arduino [https://www.pololu.com/product/2504], please follow the more specialized assembly instructions for that product [https://www.pololu.com/docs/0J57] instead of the ones in this document! The Pololu Zumo chassis kit contains the components you need to build a small, high-performance tracked robot platform.

Assembling the Zumo Attention: If you are assembling a Zumo Robot for Arduino using the Zumo Shield for Arduino [https://www.pololu.com/product/2504], please follow the more specialized assembly instructions for that product [https://www.pololu.com/docs/0J57] instead of the ones in this document! Please follow these instructions carefully to assemble your Zumo properly. 3.
Pololu Zumo Chassis User’s Guide © 2001–2019 Pololu Corporation Idler sprockets 1. Place an M3 nut in each of the two side slots near the rear of the chassis. The slots are sized so that nuts will not be able to rotate within them. 2. Place an idler sprocket on each shoulder bolt, followed by a washer. The protruding side of the sprocket hub should face the same direction as the threaded end of the bolt (in toward the chassis). 3. Insert the shoulder bolts through the side of the chassis into the nut.

Solder any connections you want to make to your motors (such as wires and bypass capacitors [https://www.pololu.com/docs/0J15/9]) before installing the motors in the chassis, as you will not be able to access the motor leads easily once the acrylic mounting plate is in place. 5.

Pololu Zumo Chassis User’s Guide © 2001–2019 Pololu Corporation Mounting plate There are two types of mounting holes sized for #2-56 screws in the rear portion of the chassis: • The middle four rows of holes have a recess for a nut on the interior of the chassis. These holes can be used to secure the mounting plate or other components directly to the chassis, as demonstrated by the screw on the left side of the picture below.

Note: if you are also adding a basic sumo blade [https://www.pololu.com/product/1410], you should place its mounting tabs on top of the acrylic mounting place so that its holes line up with the two front-tab holes and use the #2-56 machine screws to mount both the blade and the acrylic mounting plate to the chassis.

Note that the two individual contacts should be inserted into the chassis so that their solder tabs protrude through the holes in the top of the chassis and can be accessed from the exterior.
