Investigating spherical spiral forms through robotic tube bending, RobotSphere employs a robot to perform freeform bending of tubes in all dimensions with the precision required for complex geometric alignment. Each spiral transforms from a flat configuration into a double vortex pattern in the interior of the sphere.
The geometric challenge lies in the rotational alignment. The spirals rotate around the axis of the sphere, transitioning from the uniformly distributed flat elements into a three-dimensional spherical structure. Whether the system works or not depends on whether the alignment is correct in both states while avoiding intersections.
The attachment points where the spirals connect in the spherical state form the basis for a stable construction. The precision requirements drove the decision for the robotic fabrication approach: The spirals must be aligned so accurately that the folding transformation becomes technically feasible. The curved elements organize into spherical assemblies through rotational symmetry and controlled geometric transitions. The investigation remains ongoing.
