A Turing\u2019s machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model&#8217;s simplicity, it is capable of implementing any computer algorithm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 1961, &nbsp;Marvin Minsky proved which tag systems are computationally universal. A Post machine can perform any algorithm as well and its substitution system is simple in essence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This robotic Post machine is built with modular robots (Cubelets) and is the first known physical implementation of such machines. Similarly, a <a href=\"http:\/\/www.comunidad.escom.ipn.mx\/ALIROB\/CULET\/).\">previous UCL and ALIROB collaboration<\/a> was the first robotic Turing machine also built with modular robots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The success of this result has been acknowledged in the recent <a href=\"\/www.wolframscience.com\/gallery-of-art\/Robotic-Tag-System.html\">Stephen Wolfram&#8217;s book &#8220;Twenty Years of A New Kind of Science&#8221;<\/a>. The Post machine robot is referred to in the book and in the virtual gallery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, Eric Schweikardt, founder of Modular Robotics, refers to this result as &#8220;A No Longer New Kind of Science&#8221; in <a href=\"https:\/\/modrobotics.com\/uncategorized\/a-no-longer-new-kind-of-science\/\">his blog post<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project is a collaboration with the UCL, led by Professor Andrew Adamatzky and ALIROB, led by Professor Genaro J. Mart\u00ednez.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Professor Genaro Mart\u00ednez commented on the project: This international collaboration has been very productive for more than 20 years. This interchange between both laboratories include topics in: computer science, cellular automata, robotics, complex systems, art and artificial intelligence.
