This talk is an introduction and overview of a new and exciting field in robotics called Self Reconfiguring Modular Robotics (SRCMR). SRCMR is basically about modules, like Lego pieces, that can assemble themselves into anything you want (self reconfigure). You will hear how this makes a prosperous, growing, and environmentally friendly world accessible for all of us. This is possible because the stuff you need is assembled from the same modules, again and again, using no resources other than small amounts of energy. This drastically reduces the resources we use, and de-couples growth and environmental problems. Because the modules are programmable, SRCMR will also make the world completely hackable, introducing many interesting opportunities and challenges.
