Introduction to the Structure Subsystem, continued
VEX square holes are also used
as “alignment features” on
some components. These pieces
will “snap” in place into these
square holes. For example, when
mounting a VEX Bearing Flat
there are small tabs which will
stick through the square hole and
hold it perfectly in alignment.
This allows for good placement of
components with key alignment
requirements. (It would be bad if
a bearing slipped out of place!)
Note that hardware is still
required to hold the Bearing Flat
onto a structural piece.
Hardware is an important part
of the Structure Subsystem.
Metal components can be directly
attached together using the
8-32 screws and nuts which are
standard in the VEX kit. The
8-32 screws t through the
standard VEX square holes.
These screws come in a variety
of lengths and can be used to
attach multiple thicknesses of
metal together, or to mount
other components onto the VEX
structural pieces.
Allen wrenches and other tools
are used to tighten or loosen the
hardware.
Note: There are two types of screws that are part of the VEX Robotics Design System.
• Size 8-32 screws are the primary screws used to build robot structure.
• Size 6-32 screws are smaller screws which are used for specialty applications like
mounting the VEX Motors and Servos.
