This is just too cool. Someone has built a robotic grafitti artist that uses a spray can mounted on two cables. This is very, very cool.
Of course we did not call it Hektor from the beginning, it did not even have a shape, it was just an idea. There were dozens of decisions to take and problems to solve, but the basic idea was clear: Four step motors, mounted onto the wall in the four edges of a rectangle would move the can, which would be connected to the motors by something like robes, the motors functioning like winches. The can in the middle and the four robes connected to the motors would form an X, and when the can is moved by pulling or releasing each of the winches, this X is distorted.There would be so many advantages: The machine would be scalable, it would not spray within a predefined size only. One could mount the motors wherever possible and required, the only limitations would be the length of the robes, the accessibility of the locations for the motors and some other mechanical constraints. All the parts would fit into something portable, for
example a suitcase.
