The fifth annual World Robot Conference is being held in Beijing from August 20 to 25, attracting over 800,000 visitors. The event showcases more than 700 models of the latest robotic technologies and upgrades, and, this year, they can swim, fly and even perform brain surgery.

Created by German firm Festo, the ultralight flying drone was inspired by the herring gull. With a wingspan of two meters, the flight model can take off, fly and land using its own wings and just 23 watts of power – half the power used by some laptops.

Named XR-1, the cute commercial humanoid service robot is powered by a “constantly evolving cloud brain.” It can perform tasks like picking up objects, opening doors or even threading a needle, “making it perfect as a concierge, receptionist, business guide, or VIP service staff under different scenario,”according to its creator CloudMinds.
