This is a project of a friend, not my project however I have been helping with the design and building process of this first prototype.
"A delta robot is a type of parallel robot. It consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector."
This video just shows some quick sample programs I wrote to test the movement and stability of the platform after final assembly.
