Matthew Sparkes writes: "A team of search-and-rescue robots have been developed, that are capable of collaborating to form a single larger robot when faced with certain challenges. Each of the robot's three detachable modules can function independently, but when combined the modules function as a single larger and more complex robot. It is possible to cover a search area much more quickly by dividing it between several independent units. Conversely, there are also benefits to working together. A larger robot can, for instance, span larger gaps and move larger objects."
