A delta robot is a three-legged device, capable of precise control, and well suited to the fast execution of light-duty tasks. It has potential for controlling shade structures as well as apertures in surfaces.
The delta modules track the sun between 30 and 45 degrees from surface normals. Then they slowly return to their home position.
Here is an individual module:
The definition below mathematically computes the position of a robotic arm that is restricted within a two-dimensional plane of movement.
It uses basic trigonometric equations instead of parametric relationships between geometric forms.
