Shown is a rough sketch of a Repstrap design using 80/20. It utilizes 80/20s linear motion with the single unibearing system. The main reasoning behind using 80/20 is to construct a flexible system that we can easily modify and build upon. It will also give us the knowledge needed to build a larger systems.
The size is 24''x24''x18''(wxlxh)
The current design is ~ $ 180 which can be further reduced by decreasing the size. Check back for further details.
