The 15mm profile of the Extrusion has slots on on all four sides that accept standard M3 hardware. Rather than using a T-nut, which is more expensive, slide a M3 hex head screw along the slot and adjust brackets and other build materials as needed. As illustrated in the image above, the ends of the Extrusion also have a 5mm hole pitch that can be M3 tappped.

The flexibility of the 15mm Extrusion makes it a great option for arms, lifts, and other robot manipulators and mechanisms. This is one of the most compact structure pieces and allows for compact designs. Depending on the design and use case, you may wish to add additional supports to avoid twisting under high loads, also known as torsion.
The point of the extrusion system is to offer more flexibility in design than would come in a fixed pitch system. The in the extrusion allow brackets and other components to be slid along the 15mm Extrusion to an infinite number of positions
The illustration above shows how easy it is to swap, adjust and iterate designs. This works for gear mating, chain tensioning, and bracket adjustments as you are iterating.
To help with joints you may need Extrusions with beveled edges. To learn more see the section.
The REV DUO Build System has two major structural components, Extrusion and Channel. REV Extrusion is a rectangular structure rail with slots for M3 hardware on all four sides. The slots in the Extrusion allow for brackets and other items to be adjusted to any position along the rail. REV Channel is a larger structural member featuring a pattern for actuators, brackets, and other elements to be placed at set intervals. Channels have a combination of a fixed pitch based system (known as the Extended Motion Pattern) and an extrusion system for design flexibility.
All REV DUO structural components are M3 hardware compatible.
The 15mm extrusion system allows for a more flexible, iterative process than fixed pitch systems. Fixed pitch based systems have a set pattern of holes to use for mounting; everything that is mounted is spaced on a multiple or a set fraction of the standard pitch. In contrast, the 15mm extrusion system allows for flexible mounting positions along the slots. Simply slide any brackets that need to be mounted into the appropriate slot and adjust to the desired position.
We believe that the easier it is to adjust your design, the easier it is to iterate and improve that design.
See any of the pages linked below to learn more about how to use the extrusion system.
While the 15mm Extrusion does not have a fixed pitch other components in the REV DUO Build System do. have M3 holes on an 8mm pitch. While have the Motion Pattern, a circular M3 hole pattern on a 16mm diameter is used to mount to REV Robotics shaft accessories.
, , and feature the Extended Motion Pattern, a modified circular M3 hole Motion Pattern on a 32mm diameter. This repeats down the length of channel to mount bearings, shafts, brackets, and more.
The Extended Motion Pattern starts with M3 holes on an 8mm pitch down the center of the Channel. Each of the holes on the center line pitch forms the "base" for an equilateral triangle with 8mm sides that extends outward towards the edges of the Channel. Every 16mm a center hole is opened up to become a 9mm bearing seat to attach shafts and bearings.
REV 45mm Flat Plate is a 45mm wide, bendable metal featuring the Extended Motion Pattern. This product comes in various lengths. The Extended Motion Pattern supports M3 hardware for attaching brackets, extrusion, and channel.
Material: 5052 Aluminum
Length: Various Lengths
Width: 45mm
The alloy of aluminum used in the flat plate makes it more malleable than other structure pieces in the 15mm Build System. Utilize the flat plate to create curved aspects for your robot like a shooter hood, an intake, or a bumper.
Step 1: Approximate the diameter of the curve you want.
Step 2: Find an object, like a can, that is close to the diameter you need.
Step 3: Adjust the flat plate around the object with your hands or hand tools until you reach your desired curve.
has a 45mm x 45mm square profile, and is designed to work seamlessly with existing . It can be used in locations where additional torsional strength is required. On the sides of the channel is the Extended Motion Pattern which uses for attaching brackets, extrusion, and channel together. Locations for mounting bearings, shafts, motors, and servos are available every 16mm. Slots on the top of the channel accept standard M3 hex-head bolts or nuts, rather than expensive t-nuts. The top of the channel also has the Motion Pattern with M3 holes on a 16mm diameter circle pattern repeating down the channel.
Material: 6063-T6 aluminum
Width: 45mm
Length: Various Lengths
Channel can be cut to length if necessary, but care should be taken to ensure cuts preserve the necessary portions of the motion pattern for the overall robot design
Similar to the C Channel, the U Channel is great for applications that need additional torsional strength. The advantage of the U channel over the C Channel is that the shape, combined with the Extended Motion Pattern, allows for two points of shaft support. This reduces the need for additional support brackets in different applications, such as drivetrains and arms.
Use the U channel in places where you need a high level of torsional strength.
The combination of the pitch and extrusion systems featured on the U channel allows flexibility in design and iterations. The extended motion pattern featured allows for easy placement of moving parts, for additional constraint and support of motion.
The major use applications are that Core Hex Motors (REV-41-1300) and Servos (REV-41-1097) can fit completely within the U Channel and be mounted flush against the channel without the need for brackets. Simply attach build components with M3 hardware.

L Beams are a structural element for small load applications or as a supporting component on a larger load application. They’re compact and lightweight and provide more strength than a Flat Beam. Use them to create a corner between plates, attach channel to extrusion, or for fastening your own creations.

The C Channel uses a combination of a fixed pitch system and an extrusion system to make it easy to iterate robot designs. The Channel system overall is compatible with standard M3 hardware , and is designed to work seamlessly with existing 15mm Extrusion and 15mm x 30mm Extrusion. The extrusion system has slots that allows flexible bracket positions for easy Channel to Extrusion connection.
The 45mm wide side of the channel features the Extended Motion Pattern which uses M3 hardware for attaching brackets, extrusion, and channel together. Locations for mounting bearings, shafts, motors, and servos are available every 16mm. Slots on the 15mm sections of the channel accept standard M3 hex-head bolts or nuts, rather than expensive t-nuts.

The C Channels are great for creating a sturdy or for use in areas where additional torsional strength is needed.
The combination of the pitch and extrusion systems featured on the C channel allows flexibility in design and iterations. The extended motion pattern featured on the 15mm x 45mm C Channel allows for easy placement of moving parts, for addition constraint and support of motion. The extended motion pattern can also allow easier replacement or swapping of parts on interior portions of the robot than the 15mm Extrusion, depending on robot design.
