Quadbike: Bigger Is Better

[Tom Wilson] has finished his latest human powered quadcycle. The BigDog, as its called, seats 4 persons in lawn chairs who pedal to their destination. We say latest, for [Tom] also made a slightly smaller version called The DogSled. Some improvements include being taller (8 feet total), larger (11 feet by 6 feet), and surprisingly lighter (over half the weight, bringing it in to 450 pounds). The build process is just as impressive as the bike itself; using pneumatic disk brakes to golf cart axles to even drainage pipe, its a perfect fit for burning man. Catch a video after the divide.

Distributed Flight Array

Though it is in the beginning stages of development, the Distributed Flight Array is already looking very interesting. Each unit can scuttle across the ground using the down force from its prop, but when 4 or more join forces, they can take off and fly. The documentation shows that they should be smart enough to fly in random configurations, though in the video we only see the standard 4 prop layout. This is being worked on by the same people who produced the balancing cube.

Hexacopter


Quad copters have been pretty popular for the last few years, but this one is new to us. Take the same basic layout, but bump it to 6 rotors. Then you’ll have the hexacopter (google translated). With 6 rotors, built in GPS and stabilization and a camera mounted on the bottom, this thing is pretty well equipped. You can see how agile and stable it is in the video above. We know it isn’t necessarily new, but it is new to us. Of course, you don’t have to stop at 6 rotors. You could always just continue on to 8.
