The physical module is the essential building block of all the modules the we created. It unifies everything together and creates a unique design and multiple configuration possibilitys. The specially aligned holes allow for custom cuts and the material that was used, wood can be manipulated however it is needed to be by using tools. Additionally, all of the files are open source so any additional peices that need to be created can be. The building blocks I have used can create 3d or 2d objects very easily and does not require a 3d printer or any first hand knowledge for assembly. Some of the items in the kit are teethed and this adds structural integrety to the robot that is being created. Also, the teeth also allow for a solid connection with wood glue or screws. In all, I created an all purpose robotics kit.
