SuperBot is a modular, multifunctional and reconfigurable robot, designed by Dr. Wei-Min
Shen and his team at the Information Sciences Institute at USC. You might say that SuperBot is
really a set of individual robots that work together to move around and solve problems. Dr. Shen
has been awarded more than $8 million in grants from NASA, DARPA and the NSF to continue his
research, including constructing a 100 module prototype to demonstrate how SuperBot might be used
in space exploration.

Dr. Shen points out the limits of the current set of robotic devices used for space exploration:
One of the most challenging issues for human-centered long-range space exploration is performing
complex tasks in environments that are not human-friendly.... the traditional approach of building
separate robots for separate tasks (such as the Canada Arm and surface rovers) may no longer be
adequate for affordable space exploration as the required robotic tasks become diverse and the need
to pack many functionalities into a single launch volume increases.
Dr. Shen proposes the SuperBot modules as a way to meet this goal. Each module is a "robot" in its
own right, with microcontrollers, sensors, communications, power supply, three degrees of freedom
and six connecting faces to dynamically connect with other modules. At launch, or when landing,
SuperBot can pack itself into a minimum amount of space.

Upon arrival, SuperBot can unpack itself
and take any of a wide variety of forms. For example, it might form several exploration rovers, one
SuperBot capable of rolling down hill, another twisting "sidewinder-style" over level sand while another
forms a SuperBot climbing robot to take on more challenging terrain.

SuperBot will help NASA to reduce costs and simplify operations by reusing robotic components from
mission to mission. If the robotic modules are truly interchangeable and interoperable, the need
for redundant parts on a given mission can be reduced, thus lowering payload mass and cost. Mission
reliabilty and safety would be enhanced, since the modules themselves would know how to perform
tasks, and would require less active direction from astronauts or ground crews.
Dr. Shen hopes to have his 100 module SuperBot operational and ready for testing in a desert
environment by 2008.

how to link themselves with other modules.

Golden Age legend Jack Williamson wrote a great story titled The Infinite Enemy, published in Thrilling Wonder Stories in 1938, in which an alternate universe is found to contain a being comprised of metallic cubes.
