First, the ONE controller from the line of R:ED robotics sets has 16 ports, which can handle 2 motors and 14 sensors simultaneously. This enables multifunction robot designs that can be sensitive to sound and light, able to go around obstacles, and perform other functions at the same time. Second, the kit can be programmed in 5 programming languages, where other products can only use 1 or 2. Third, R:ED is made in Russia, which accounts for a significantly lower price than other functionally comparable kits.
