Australia's Robotronica spectacular: Drones, humanoids and agbots

On Sunday, big and small robots took over the Queensland University of Technology in Brisbane, Australia for Robotronica, in a celebration of futurism and technology

The event featured everything from a robot playing Connect Four against kids determined to thrash it, to speakers like Ian Bernstein, the founder of high-tech toy company Sphero, who designed a new droid for the upcoming film Star Wars: The Force Awakens. There was even a performance by a robotic marimba player.
