And while some of the droid’s functions may be a few years off, a new generation of helpful robots have arrived and can act as everything from personal assistants to camera operators.While they may be designed to do different jobs, a handful of the robots featured at the RoboBusiness conference in Boston have one thing in common – they are designed to follow their leader.A robot called Budgee is designed to follow elderly and disabled people to carry heavy items, such as shopping, Wired’s Tim Moynihan reported. Made by Five Elements Robotics, the robotic assistant looks friendly and features a netted basket.To make Budgee follow, its owner will wear a small device and uses an app to set the distance between them and the following robot.The helpful droid will be able to tail its owners at speeds of up to 2.4mph (3.9kph) and send them a text if it can’t keep up. Sensors prevent it from falling down steps or bumping into obstacles.Budgee will come in different sizes, be able to be folded up and weighs 20lbs (9kg), while it will be capable of carting around 50lbs (23kg). It will go on sale in January from $1,400 (£879).(dailymail.co.uk)Bakudaily.Az
