Whether organizing parts, following a set of build instructions, or building a custom design, identifying a part correctly can be crucial to your success.
The VEX IQ Parts Ruler is a handy tool to help identify parts.
Note: when printing the .pdf be sure to set to 100% scale.
This article will explain:
Using the Ruler to Identify Parts
The VEX IQ Parts Ruler can be used to identify parts while organizing parts or following a set of build instructions. The scale on the ruler is 1:1, so parts can simply be placed on top of the ruler.
Measuring Beams and Plates. Example shown is a 2x7 Beam.
- 2 indicates a width of 2 pitch units.
- 7 indicates a length of 7 pitch units.
Measuring Standoffs. Example shown is a 4x Standoff.
Measuring Pulleys. Example shown is a 30mm Pulley.
Measuring Gears. Example shown is a 12 Tooth Gear.
Measuring Sprockets. Example shown is a 16 Tooth Sprocket.
Measuring Pins. Example shown is a 1x1 Pin.
Measure Specialty Beams. Example shown is a 30° Angle Beam.
Using the Ruler While Assembling a Robot
The VEX Plastic Parts ruler can also be used as a measuring tool to measure parts and distances. This can be very helpful when designing and assembling a custom robot which does not have specific instructions regarding the selection of parts.
Tip and trick: The .pdf of the VEX Plastic Parts Ruler can be printed out on a clear plastic transparency. This will allow the ruler to be overlaid on the robot and measurements can be made by measuring through the ruler.
Here are some examples of using the ruler while assembling a custom robot.
Measuring the distance between beams on a robot chassis. This example shows the distance between beams on the robot chassis measuring 11 pitch or 5.5 inches.
Using pitch to measure the length of a shaft. This example shows an 8 pitch shaft.
Using inches/millimeters to measure the length of a shaft. This example shows a 4" shaft (4 inches/102 millimeters).
Measuring the number of chain links in a chain/sprocket system.
