At last year's Toy Fair, Innovation First - the creator of the hugely successful Hexbug creepy crawly robot range - branched out by introducing Bobble Bots, helped no end by a tie-in with Moshi Monsters. This year it has adapted its Hexbug nano technology for another new brand, Tagamoto.Tagamoto is the collective name for a range of miniature robot cars and playsets, which take the mild scariness away from the traditional cockroach-like nanos, but add all-new technologies to make them, possibly, even more fascinating.The playsets build roads and junctions in much the same way as many other car-related toys, but with a major difference. At points in the road, a child can place barcode stickers and these are read by the travelling cars.Each barcode will effectively make a car do different things. Some of the cars feature headlights, so when running over specific barcodes they can be forced to switch them on or off. Other barcodes mean a car horn can be activated, a vehicle forced to stop, and so on.The cars come in all manner of different shapes - although not sizes as they need to fit on the track - and there are 26 planned to be available in time for launch later this year. Some will come with the track playsets, others as standalone collectibles.Prices will range from \u00a37.99 for the vehicles with "Light & Sound", while playsets will be available at different price points up to \u00a329.99.We can see these being huge for Christmas. Bigger than Hexbug even.
