Basic ‘Bot Guide for REV- Part 2
Revision 1: 10/29/2020
Introduction to this Guide
About This Guide
The Basic ‘Bot Guide is designed to be a resource for teams looking for a step-by-step instructional for building
a robot and a basic armature for the
FIRST
Tech Challenge competition. There are multiple versions of this
guide, previously called the “Push Bot Guide”.
This version the
Basic
‘Bot Guide for REV
-Part 2
has been created to use the new and differing parts in the
2020-
2021 season’s REV kit of parts and builds upon the 2020-2021 Basic ‘Bot Guide for REV- Part 1 which
was released earlier in the season.

the same time.

Tips and Tricks
•
Make sure that set screws are installed in every axle hub, motor hub, and axle collar.
•
Refer to the legend provided in the Kit of Parts, if any parts are unfamiliar.
•
Make sure that all assemblies are square. It is hard to drive a crooked robot straight!
•
The drive wheels are powered by two DC motors located on the back of the robot, which are relatively
heavy. This weight is needed to help the wheels grip the surface better.
•
Omni wheels should be located on the front of the robot, which allows the robot to turn more easily.
The omni wheels can slide sideways with very little friction due to the rollers.
•
Unless otherwise noted, the top image in each step shows the necessary parts; the lower image shows
