Kids' tech: the best children's gadgets for summer holidays

With the long school summer holiday well under way, you may need a bit of help keeping the kids entertained. From walkie-talkies and cameras to tablets, robot toys and fitness trackers, here are some of the best kid-aimed tech to keep the little (and not-so-little) ones occupied. Lots of tech toys are fads but my longtime favourite has stood the test of time as a modern update to remote control fun. Sphero is a ball you control using a smartphone or tablet, and has hidden depths, with games and educational elements also available. The mini Sphero ball is a lot of fun to drive around and small enough that overexuberant indoor excursions won't result in broken furniture and scuffed-up paintwork.
