Imagine the LEGO bricks which can be assembled and connected in a myriad combinations. Each of a modular-robot is individually a complete robotic system and has a power supply, micro- controllers, sensors, communication, three degrees of freedom, and six connecting faces (front, back, left, right, up and down) to dynamically connect to other modules.
Implications - Called the Superbot, this mechanical wonder's ability to reconfigure in various shapes and systems allows it to perform different tasks. Examples include rolling, climbing or even burrowing in the ground. Despite it's solid shape, the design does allow "flexible bending, docking and continuous rotation," according to Eurekalert.org.
The Superbot was designed by Wei-Min Shen of the University of Southern California's Information Sciences Institute.
