Pololu 5" inch Robot Chassis RRC04A - Transparent Gray

RRC04A with Arduino Duemilanove USB Board

This Transparent Grey chassis base plate is a round piece of 1/8" (3 mm) acrylic with a 5" (127 mm) diameter and cutouts for building a differential-drive robot chassis based on our micro metal gearmotors and 42×19mm wheels. The chassis has assorted general-purpose holes and slots that support many configurations of sensors and other robot components.

 This chassis has a lot of holes in it to allow for many different mounting options. The picture below shows where different microcontrollers can be mounted.

Some Compatible Components

There are lots of holes so a lot of things can be fitted to this chassis and because it is acrylic plastic it is easy to saw, drill and glue if you need to.

• The Orangutan SV-328 robot controller with six different mounting options.
• The Arduino Duemilanove controller board with four different mounting options.
• The QTR-8RC reflectance sensor array (both six and eight sensor options) with four different mounting options.
• The Pololu carrier with Sharp GP2Y0D810Z0F digital distance sensor 10cm with eight different mouting locations.
• The 3pi expansion kits.
•  Pololu 1" and  Pololu 3/8" ball casters.

You might find our premium jumper cables helpful in connecting various components.

Included Spacers

The laser-cut chassis is designed to work with the Pololu encoders. If you do not use the encoders, you can use the two included spacers that keep the chassis at the same height. The spacers are cut out of 1/16" clear acrylic.

Using the chassis

The motors can be mounted on either side of the chassis (top or bottom). With the motors mounted on the bottom, the chassis will be roughly 1" from the ground, and you can use the Pololu 1" (or 3/4" with spacers) ball caster as a third point of contact with the floor. With the motors mounted on the top, the chassis will be a roughly 0.4" from the ground, making the Pololu 3/8" ball caster with the included 1/16" spacer the best fit.

There are many different ways to connect the compatible components to the chassis. You can refer to the diagram showing where compatible components can be mounted for further information about where you might mount various components. Some configurations require standoffs. You can see additional pictures of examples in the pictures viewer above.
