Some robots, cranes and chutes for scenery. This set can help making maps that look in construction, with little robots moving blocks of road and other stuff around.
Most stuff (everything that is yellow) can be colored to white/blue/green/red/black using the in game color tool.
The base of the crane is designed to fit inside a circle hole block (like 5-1-1-2) + the ring from the moving items (official item 1-9-3-1)
