Robots and Emotion Prabhas Chongstitvatana CRIT 2012

Future Robots and autonomous agents will increase in number. They will serve more roles in human society.

Perceiving human emotion can be one of stimulus in communication between human and robots.

Conclusion A robot that can express and perceive human emotion Sociable Robot

Need Robots perceive our need. We command robots. Robots adapt their behavior.

Robots situated in human world Learn by trial and error Inventing and mixing up its stock behaviours to response to a new situation

Human emotion has been studied in term of arts and design

Robot Perception N. Auttanugune and T. Horprasert, Head Pose Estimation using Motion Matching. in 15 th International Workshop on Advanced Image Technology, (Ho Chi Minh City, Vietnam, 2012)

Open-end design achieves with design by evolution

Evolutionary Algorithm

Genetic Algorithm Create population While not terminate – Evaluate – Selection, recombination, mutation

Lead-free Solder Alloys Lead-based Solder Low cost and abundant supply Forms a reliable metallurgical joint Good manufacturability Excellent history of reliable use Toxicity Lead-free Solder No toxicity Meet Government legislations (WEEE & RoHS) Marketing Advantage (green product) Increased Cost of Non-compliant parts Variation of properties (Bad or Good)

Sn-Ag-Cu (SAC) Solder Advantage Sufficient Supply Good Wetting Characteristics Good Fatigue Resistance Good overall joint strength Limitation Moderate High Melting Temp Long Term Reliability Data

Combine with Genetic Programming

Experiments Thermal Properties Testing (DSC) - Liquidus Temperature - Solidus Temperature - Solidification Range 10 Solder Compositions Wettability Testing (Wetting Balance; Globule Method) - Wetting Time - Wetting Force

Human in the evolution loop

Evolution + Emotion Perception = Sociable Robot
