Place your instructions on the tile reader, press go and see your robot complete the program! The tiles can be placed either portrait or landscape depending on how the child wants to lay out their program and if they want to debug their program, simply swap the tiles and press 'go' to try their program again. Connecting to a Blue-Bot® or Rugged Robot couldn't be easier, turn the robot on, press connect on the Reader and wait for your robot to go blue to show it is connected! Key features: • Bluetooth connectivity • 10 position slots • Rechargeable • Speaker for audible feedback • Connect up to three units together • Compatible with both Standard and Extension tiles • Physically correct sequences and algorithms.
