Surgical robots are commonly used in minimally invasive surgery and their accuracy holds the key to a successful operation. CUHK researchers have developed a world-first AI system with a novel deep learning method to optimise the gesture recognition of robots. The intelligent cognitive assistance not only allows robots to operate with greater precision for a safer surgery, but also wins patients’ trust in robotic surgery.

But the charm of LEGO knows no bounds. In fact, more and more adults nowadays show an increased interest in tinkering with these brightly hued bricks.
