# Mobility

## Using the Grid for Motion

Motion components are also designed to work within the Robits system. The 1 × 1 inch Robits tube profile includes bushing holes at 1.5 inch intervals, providing mounting locations for motion components such as drivetrain and arm assemblies.

Robits carriers provide additional support for rotating shafts. Shaft carriers incorporate a hex feature for transferring torque, while bushing carriers allow hex shafts to rotate with low friction. Mounting brackets allow for interfaces between actuators and structural components. 

These components share the Robits design language, so you can easily change the location of a pivot, gear, or support while keeping the surrounding structure largely unchanged.
