The Builder is essentially a large print-head on legs that is used by the Ai to create the garden artefact. The bot produces the grid by depositing materials in layers – it is told by the Ai what to print and where. The Builder is constructed from wood, and uses simple mechanical processes to move around. Altho it has sensors onboard, its movement is controlled by the Ai which communicates with it wirelessly.
The Builder will move on a hexabot base (the clip shows an octant base but the principle is moreorless the same):
The bot parts will be created using wood
