Currently, on-orbit construction and maintenance work is primarily accomplished by astronauts, during extra-vehicular \"space walks\". These are expensive and pose risks to the astronauts' lives. In the future, it is expected that an increasing number of on-orbit construction missions will be performed by autonomous robotic systems. Large structures will be constructed using modules made of lightweight materials, and will be very flexible. In MIT's Field and Space Robotics Lab (FSRL), algorithms are being developed to optimize the transportation and assembly of large, flexible structures. To test these algorithms, it is necessary to have laboratory flexible beam modules with similar properties to structural space modules. This thesis presents a design for a set of flexible modules which have comparable properties to proposed space modules. These modules are designed to be manipulated by a team of laboratory robots. The design process and final design of the flexible beam, which comprises a majority of the flexible module is presented.
