Preface
This builder’s guide has been developed to provide students with positive experiences in robotics engineering. With the
assistance of this guide, students will learn to use the TETRIX PRIME parts and myRIO to design and construct three different
robots. After using this guide, students should be able to use the TETRIX PRIME parts to construct a robot of their own
design.
Safety Information
Mechanical
• Keep fingers, hair, and loose articles of clothing clear of gears and moving parts.
• Never pick up the robot while it is moving or the servo motors are running.
• Remove any burrs caused by cutting the metal beams.
Electrical
• Make sure the power is turned off when the robot is not in operation.
• Do not operate the robot in a wet environment.
• Always power down the robot before making any changes.
• Use caution when working with bare wires to avoid creating a short circuit situation.
• Route wires carefully and secure them if necessary to avoid damage to the wire or its insulation.
• Mount the battery pack and all electronic components securely.

Set Components
This section documents all the parts included in the kit, including images, quantities, and part numbers. The part number
of each part will match the part number noted on the label of each part bag. The part bags may contain one or more parts,
and there may be more than one bag of a particular type of part. Instructions for purchasing additional parts are found at
the end of this section.
The beams are named by the number of small holes on one side of the beam. Do not select beams by counting the larger
holes.
2x – 15-Hole Beam 40207
2x – 13-Hole Beam 40206
4x – 8-Hole Beam 40205
4x – 7-Hole Beam 40204
4x – 6-Hole Beam 40203
4x – 5-Hole Beam 40202
4x – 4-Hole Beam 40201
1:1 scale
To identify TETRIX PRIME beams, count the small holes. The
example above is a 4-Hole Beam.
