I’m a sucker for remote controlled helicopters. They’re a blast whether you use them indoors to terrorize your colleagues or outdoors to terrorize your neighbours. But as cool as remote helis are, they don’t hold a candle to remote quadrocopters, or quad-rotors as they’re sometimes called.
Especially when said quadrocopters are remotely controlled by a computer to execute a complex yet beautiful set of manoeuvres. Did I mention there’s also music involved?
Check out this amazing video that demonstrates the potential of these tiny machines. The performance was created by Vijay Kumar and his team at the General Robotics, Automation, Sensing and Perception (GRASP) Lab at the University of Pennsylvania and presented as part of Kumar’s TED2012 talk. This group of engineers studies how swarms of robots such as these quadricopters can work together – sensing each other in real time and reacting appropriately.
I’m not the first person to make the connection between this performance and the zany musical exploits of perennial YouTube favourites OK Go, and for good reason: each takes music performance to a whole new level.
If you’re curious, do a few searches for quad-copter or quad-rotors on YouTube – you’ll be amazed at what you’ll find. These four-rotor machines are supremely maneuverable and can hover in one spot with a greater precision than a single-rotor craft.
When we attended CES 2012 earlier this year, we had a chance to see the latest version of the Parrot AR.Drone, a quadrocopter with some unique features and a price tag that is within reach of most hobbyists: Approx. $300 USD. While not quite as powerful or precise as the models being flown by the team from GRASP, the AR.Drone is still a fantastic piece of robotic tech.
Let’s just hope we never anger the computers controlling these flying machines, or we might be the next to be terrorized!
