RH3-Y, Western Switzerland Univ. of Appl. Sc., Yverdon-les-Bains, Home 2008, Suzhou-China 4 Models for emotions  Emotions  Result from changes in perception and consequences  Related to convergence/deviation between status and goals  Lead to strategic changes  Experts suggest 2D or 3D emotional space  Arousal: activity level (re. Energy, quantity of perceived information, urgency and intensity of desired changes, of planned actions). Always positive. Or zero.  Valence: happiness degree; can be negative (re. Also benefits and costs)  (Stance)  References:  Goris 2008, Lim 2007, Garcia-Rojas 2006, Russel 2005 and 1997

Flashing signal Out 1)  Shout (re. RH2-Y barking in Atlanta)  Move (dance?)  Waive arm?  Those who know RH-Y also know its motor voice or how the right wheel tends to lag behind when batteries run tired
