Star plot - MER ID sample designs

http://start1.jpl.nasa.gov/caseStudies/autoTool.cfm

 

In this star plot, four different design samples (MER IDD) are compared and sorted by seven metrics variables (accuracy, collision, trajectory completion, time, mass, actuator saturation, and link deflection).  According to the description underneath, in this star plot, the center represents the most desirable result. Each design represented on the plot has a different color; in red, they also added a handcrafted MER ID design, for comparison and validation purposes.  It is clear that each design has its setbacks and its advantages, so the way to determine the best design is to decide which metrics are the most important, and then to see which design fulfills these metrics the best.  In this case, the website description says design samples 3 and 4 fulfill the important metrics the best.
