Hexacopter: Similar to a quadracopter, except with 6 blades instead of four. Hexapod: A 6-legged robot which walks like a spider. Why not combine the two? These makers decided to combine the them into one horrifying contraption. It crawls like a spider and flies like a helicopter. See it in action:
To build it, they started with a standard hexapod electronics kit and replaced the structural components with lightweight, carbon fiber. Next, they added the a six-rotor configuration to provide stability during flight. As you can see, the results are eerie, but fantastic!
