Firstly, the ONE controller from R:ED kit range has 16 ports which enables you to connect 2 motors and 14 sensors at the same time. Thanks to that, it is possible to design multifunctional robots that can simultaneously respond to sound, avoid obstacles, react to light and perform many other functions. Secondly, our kit is programmed in 5 languages, while other kits can only use 1-2 programming languages. Thirdly, R:ED has been developed in Russia, so the kit costs far less than its analogues with similar functions.
