For a top world congress on humanoid technology, hundreds of robotics experts and their whirring, flashing robot creations gathered in Madrid on Wednesday.
One of the guest exhibits, which is a 1.65-metre (five-and-a-half-foot) humanoid robot weighing 80 kilos (176 pounds) said, "Hello human friends, I am Reem-C."
Robots of different size, big and small, showed off their skills at dancing, cooking and even training accident victims to walk again.
One of the participants Frederik Bengtsson, a Swedish student said, "There is quite a big explosion of robots currently."
430 participants from 31 countries joined the congress on humanoid technology. Bengtsson entered a competition at the congress to programme some of the robots and he said, "The technology is getting cheaper and faster so it`s a really fast-growing area, like computing a few years ago."
Santiago Martinez from Carlos III`s Robotics Lab said that the researchers are now trying to program emotional responses in robots.
"But making a machine that can think is complicated, We will not see it in the near future," he added.
The 2014 International Conference on Humanoid Robots held until Thursday at Carlos III University in the Spanish capital.
