The only thing that differentiates this remote control safety cage RC helicopter from the one designed by robot researchers at the EPFL is an $80 price tag. Because you can actually buy this one from Kyosho, and don’t need a research grant to build your own.

Otherwise, you can crash this eight-inch sphere into the walls, the furniture, and even the people in your home. Its plastic 360-degree roll cage will shrug off any impact and prevent its spinning rotors from causing further damage. It’s basically the perfect flying toy for amateurs who’ve never piloted an airborne craft before, or who may never actually get the hang of it. Now if only there were full-sized cars as safe as this.
