Assembly Tips

In addition to the many tips which are provided in the build instructions, here are some additional general assembly tips which will assist you with your first robot.

Information on Parts

The VEX V5 system has many different types of parts. Substituting the wrong part for an instruction set in most cases does not work. An understanding of the V5 parts can be very helpful.

Structural - Structural metal parts include C-channels, U-Channels, Angles, Rails, Plates, and Bars. These parts can be purchased in steel or aluminum. The instruction sets within the Builds and the STEM labs should require no modifications to the structural pieces. However, custom-designed robots may require the structural parts to be cut and/or bent into custom pieces. For more information refer to, Design a Chassis - Structure for VEX V5.
Fasteners - Earlier versions of the VEX Educational Robot system utilized screws with a hex socket heads for tightening. The V5 system uses star sockets on the heads of the screws. Star sockets are less prone to stripping and allows you to firmly tighten screw and nut systems. For more information on fasteners refer to:
Wheels - There are many different options for wheels to use on a V5 Robot. The wheels come in several different sizes and are available in traction versions or wheels designed for omni-directional motion. For more information about wheels refer to, Drivetrain - Drivetrains for VEX V5.
Gears and sprockets - The gears and sprockets which are used on the V5 robot to transfer power from the Smart Motors are sized by their number of teeth. For more information refer to:
- Gear Ratios - Motor for VEX V5
- Spur Gears - Motor for VEX V5

Assembling Chain and Tank Treads

The VEX V5 system has chains and tank treads which can be used with sprockets. These parts are assembled by connecting individual links together and this allows for custom lengths to be used between sprockets. The links can be assembled by bringing two together at a slight angle, aligning the hole on one link with the boss on the next. Then twist the two links until they snap together as a unit.

Example of High-Strength Chain.

Example of Tank Treads.

To disassemble to chain/tank tread links, reverse the procedure.
