Humanoid robots wave, carry out household tasks and demonstrate different ways of moving at a robotics showcase in Brussels.

The event at the European Parliament highlights growing interest in robotics as Europe faces an ageing population and a shrinking workforce. Researchers say humanoid machines could eventually take on factory tasks without major changes to existing infrastructure, although the technology remains largely experimental.

Developers say AI is improving robots' ability to perceive their surroundings and handle objects, allowing them to work alongside people and adapt to changing environments.
