MOTION COMPONENTS
All REV Robotics Motion Components, including wheels, sprockets, gears, and pulleys, all have a uniform thickness of
15mm (Figure 47). The purpose of this is to improve the iterative design experience. Changing from gears to a solution
with chain and sprocket, or switching to directly driving a wheel, will not require any frame or spacer changes.
Figure 47: All Motion Parts Share Common 15mm Part Thickness
All Motion components have a M3 bolt hole mounting pattern that is on an 8mm pitch as shown in Figure 48. This makes
it easy to directly mount to brackets and extrusion.

Sometimes, it may be desirable to stack together multiple of the same gear or sprocket on a shaft. As a best practice, all
components should have the alignment notch (Figure 49) oriented the same direction on the shaft. The alignment notch
can be found on the raised hub on either side of the gear or sprocket.
