Abstract: A toy for teaching the logical thought process of computer programming has a plurality of stackable blocks with each block having a memory for the storage of at least one computer programming instruction. When the plurality of stackable blocks are mechanically stacked, a plurality of instructions are electrically connected forming a computer program. A main block is configured so that the plurality of stackable blocks can be mechanically stacked on the main block. A computer is electrically connected to receive the computer program. A robot is connected to the computer, with the computer controlling the robot in response to the computer program.
