Using the Ruler While Assembling a Robot

The VEX EXP 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 EXP 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.
