"Mathematically, they're really interesting," he said.
"I watched a video solving a Rubik's cube and thought it was so fun."
Mr Pidden's robot uses dual webcams to scan the cube, a custom mechanism to manipulate the faces, and a fully self-built solving algorithm to generate efficient solutions.
The student now plans to study for a master's degree in robotics at Imperial College London.
The Rubik's cube is a combination puzzle invented by Hungarian sculptor Ernő Rubik in 1974.
The goal of the puzzle is to arrange the squares so that each of the faces of the cube displays a single colour.
The original version has three-by-three squares on each face. The four-by-four, also known as "Rubik's Revenge", was invented by Hungarian Péter Sebestény in 1981.
