Building your robot with modular subsystems saves hours during testing and events. Modularity means each mechanism can be treated like a black box—built, tested, and repaired independently. Standardization ensures that parts and tools are consistent across your design.
A modular subsystem is self-contained:
It bolts on with a few screws or brackets
Has a single set of wires or cables going in/out
Can be removed without disturbing unrelated systems
Examples: A fully removable arm module, drivetrain pods, intake trays, or even pre-wired electronics boards.
Faster Repairs: Replace a broken part without taking apart the whole robot.
Parallel Development: Mechanical and electrical team members can work on different modules simultaneously.
Easier Iteration: Test different versions of a mechanism without redesigning the whole robot.
Consistent Mounting: Use standard hole spacings and brackets (e.g., 16mm grid, extrusion mounts).
Use common motor types (e.g., all GoBILDA 312 RPM)
Stick to one bolt size per use-case (M4 for structure, M3 for electronics)
Use keyed motor shafts or set screw flats consistently
Design 2D brackets and spacers around common thicknesses (3mm, 6mm, etc.)
