I cannot find a height that the field may be elevated to. Is there a specific height for VEX IQ competitions?
At VEX Worlds, the fields will be elevated 18 inches.
Rule <T5> from the Game manual
" At many events, the playing field will be placed on the floor. Some event partners may choose to elevate the playing fields. At the 2017 VEX Robotics World Championship the platforms will be 18” high."
