Lego GBC Utility Modules
Lego GBC Utility Modules support a layout and help them run efficiently, these include Reservoirs, Trains, Bridges and Returns
Reservoirs
For stabilizing ball flow and ball storage while a downstream module is being fixed.
Layout Allowance
A minimum of 1 and then 1 every 20ft / 6m
See GBC Reservoir Lift in Yellow for details on this module
Trains
For returning balls to the start of a loop or filling gaps in layouts
See GBC EV3 Truck for details on this module
Layout Allowance
See GBC Table Layout, most layouts longer than 10ft / 3m will have a train in them for layouts longer than 40ft / 12m, a loop layout with a bridge is a better option
Bridges
For enabling easy access to the inside of table loops by bridging a gap in the table
Layout Allowance
Essential for loop layouts
- 1 for 40-80ft / 12-24m
- 2 for longer layouts
Splitters
Splitter modules split the balls into 2 paths allowing modules to run in parallel
Layout Allowance
Optional
Ball Returns
For making it easy (and fun) for people to return lost balls
Layout Allowance
Optional
Down and Up
A pair of modules used in a lowered area of a layout so that young children can see the modules
Using 12″/25cm milk crates as table legs will give a drop of around 18″/45cm this would require a Down module of 20″/50cm and and Up Module of 24″/60cm
Lowered areas need constant supervision due to the young target audience
Layout Allowance
Optional
Requires a lowered table and an additional person to watch
