The Blue-Bot TacTile Reader is a unique and alternative way to program your Blue-Bot! Place your individual tiles in a row to build up a sequence of instructions. The tiles can be placed either portrait or landscape depending on how the child wants to lay out their program. Up to three readers can be connected together so children can build a program of up to thirty steps for an exciting alternative to using a tablet. Design and create complex algorithms and see where Blue-Bot ends up! This is also a rechargeable unit. 25 TacTiles included.
