Constructing a robot capable of solving a Rubik's cube "on its own" has been a popular challenge for engineers, with many different designs over the years.

Cube solving robots

"Full solve time" is the average solving time including inspection.

Name Creator Year Puzzle(s) Method Full solve time Mechanism Videos Notes
Robbie Rubik Daniel Talken, Douglas Rhode, Robert Sum 1982 3x3x3 ? ~12 minutes No cameras. Scrambled cube state is typed into a computer. Cube is repeatedly flipped and the top layer turned with stepping solenoids. - Made by 3 students at the University of Illinois. (Newspaper articles: 1, 2, 3.) Ideal Rubik's Cube Newsletter Vol. 1 No. 2 (Aug 1982).
Cubot Robert Dyer et al. 1982 3x3x3 ? ~4 minutes Uses cameras (a "color vision system"). Two orthogonal manipulators grip the cube edges. - Made by a team of ~20 people at Battelle's Pacific Northwest Laboratories. (1983 Paper). Cf. this Newspaper article. Solved "any scrambled Rubik's Cube in less than four minutes": [1].
Tico and Teco Rodrigo de Almeida Siqueira 1995 3x3x3 ? ? 2 robotic arms Created at the University of Sao Paulo, Brazil. The two robots "Tico and Teco" were also given the English names "Chip and Dale". (Original announcement on Cube Lovers: [2].) Website with videos: [3].
