A couple of years ago, UK-based product designer Witek Mielniczek turned to Kickstarter to fund B – a combination radio-controlled car and quadcopter.
Its ability to both fly through the air and drive along the ground was
certainly intriguing, although its ability to traverse rough terrain
wasn't necessarily phenomenal. That's why he's now created B-Unstoppable, which swaps wheels for neoprene tank-like treads.
Micro-drones may be versatile in the air, but carry one in your pocket or bag and you run the risk of damaging its propellers. While carry cases are available for a number of models, some are catering to the micro-drone class with arms that fold away for safe storage. Two Swiss roboticists are the latest to take this approach, with a palm-sized quadcopter that spreads its wings and springs to life in less than a second.
When people suggest possible uses for electric multicopter drones, it
frequently seems like they're forgetting something – presently, most
such aircraft can only fly for a maximum of around 25 minutes per
battery charge. Horizon Energy Systems, however, is developing a quadcopter that should do a lot better. Known as the Hycopter, the fuel cell-powered drone is hoped to be capable of 4-hour flight times once completed.
