摘要:Body language is an important part of human-to-human communication; therefore
body language in humanoid robots is very important for successful communication
and social interaction with humans. The number of degrees of freedom (d.o.f)
necessary to achieve realistic body language in robots has been investigated.
Using animation, three robots were simulated performing body language gestures;
the complex model was given 25 d.o.f, the simplified model 18 d.o.f and the
basic model 10 d.o.f. A subjective survey was created online using these
animations, to obtain people's opinions on the realism of the gestures and to
see if they could recognise the emotions portrayed. It was concluded that the
basic system was the least realistic, complex system the most realistic, and the
simplified system was only slightly less realistic than the human. Modular
robotic joints were then fabricated so that the gestures could be implemented
experimentally. The experimental results demonstrate that through simplification
of the required degrees of freedom, the gestures can be experimentally
reproduced.
