This self contained slow rolling robot was invented in Denmark (released last year) and is being sold in the USA by Pitsco. No screens or external devices are required. The system uses interlocking jigsaw puzzle pieces (called "TagTile") to make a track -- each part represents a command. So you can make simple programs by laying out the commends in sequence. The robot reads the tiles by using RFID technology. The set includes a KUBO robot, one printed activity map, one blank map, and a charger.

Also available to teachers is KUBO Education (KEDU), an online delivery portal with teaching materials and "12 hours of content in which students earn their license to code."
