Mark Tilden has set himself the aim of constructing robots which are able to exist autonomously in the real world. His research mainly focuses on the fields of construction, design and cooperative behaviour studies. In "Tilden's Laws of Robotics" he summed up the guidelines for the construction of these autonomous robotic devices. With his work he aims at providing basic instructions according to which autonomous mechanisms can be constructed for various different ranges of application.
Although current technology has made great strides in building artificial reasoning machines, there has yet to be any definitive way of interfacing such "brains" with robot bodies capable of surviving real-world complexity. Almost every attempt to make truly autonomous robots has resulted in failure. Exceptions have usually involved fantastic sums of money, thousands of man hours, usually both.
