David Icke Voice-command ovens, robots for pets on show at Berlin's IFA tech fair

'Europe's biggest tech fair, Berlin's IFA, is showcasing a flood of product launches until Wednesday. Here are five trends and gadgets making waves. California start-up Varram showcased a Pet Fitness robot, which plays with cats and dogs at home via smartphone instructions, even dropping treats as a reward, while the owner is at work. Sensors in the robot help it detect and stay away from furniture to not get stuck, avoiding bored pets. The robot can be timed to play with the family pet at different times and keep track of how much activity the animal has had.
