making robots more resemble humans

French robot maker Aldebaran sees a shift in robot-human interaction. 

Previously, robots were separated from humans and used mainly in factories for repetitive tasks. 

Old generation robots were dangerous and required protective measures like cages and fences. 

Industrial era of robotics comes to an end. 

Robots are now being used in academic research labs and robotic soccer leagues. 

New generation robots are smaller, more interactive, and capable of moving in the real world. 

The $16,000 NAO robot demonstrates the changing nature of human-robot relationships.
