The REPY-2.1 is an open source mechanical module for researching Modular Robotics. It is designed to be printed on a Low-cost 3D printer, like a RepRap. It improves the previous version (REPY-2.0) by adjusting the dimensions of the module and adding connectors on the sides of the modules, which allows to form modular robots with 2D configurations.
