Simpson
Simpson refers to a whole category of 3D robots. THOR (THe ORiginal) Simpson built in 2013 by Nicholas Seward in Hot Springs, Arkansas, USA. The Simpson name comes from George Gaylord Simpson who came up with the idea of Quantum Evolution, the theory that evolution can happen in abrupt burst just like the Simpson robots. Simpson robots are characterized by a delta infrastructure with only simple revolute joints. GUS Simpson and LISA Simpson are the current models.
Typical Characteristics
- No spherical joints
- Delta arrangement
- High level of symmetry
- Minimizes number of components
As a new category of printers it will be awhile until we know exactly what is and what isn't a Simpson.
Family
- THOR Simpson obsolete
- GUS Simpson
- LISA Simpson

Future Developments
- Go back to single arm design if possible. (Increase the torsional stiffness.)
- Enable auto leveling by using the extruder as a probe..
- Add coordinate transformations in firmware.
