RE-RASSOR, the Research and Education RASSOR, is a key element of the Florida Space Institute Robotics Initiative and is based upon the NASA SwampWorks Mini-RASSOR robot and UCF’s Student developed EZ-RASSOR software. FSI, UCF, USF and FSU/FAMU design teams modified the NASA designs for student use and developed 3D printed substitutions for high cost, mission focused, NASA components. This reduced the per rover cost from ~$15,000 per rover to ~$800 for the fully 3D printed excavator and ~$400 for the 4-wheel Cart version. The RE-RASSOR’s component architecture allows the substitution of commodity parts for mission oriented pieces if desired.
The initial release of RE-RASSOR is a 4-wheel cart. The NASA Control system was replaced with a Raspberry Pi and the control package for a 3D printer and the NASA Level Drive Gears have been replaced by 3D printed alternatives. The expected cost to build a RE-RASSOR Cart is under $400.
