There are two Lego Mindstorm basic robot kits and 1 renewable energy kit in the Buley collection. The kits combine LEGO building systems and EV3 technology to provide a platform for learning about robotics and the principles of programming. The "brain" of each Buley Robot is an EV3 Brick. The Brick itself can be programmed simply, but it can also load complicated programs created with compatible software. The robot themselves can be configured according to instructions that create certain designs or in any way that can be imagined. Programming determines how the robot's sensors and motors operate in response to wireless communication.
