+code for a [simulated robot][simulated-robot] which both supports the same
+programming interface as your physical robot and has a wide array of sensors.
 
 This allows you to use the simulator and the Virtual League to learn about
 writing code for a robot as well as developing the code for your physical robot
 before it's fully built. The Virtual League is thus a both a first test of your
 code as well as an early opportunity to explore strategies for competing against
 other teams.
