●Innovation Award Nomination●at World Championships

Final Challenge World Championships●Medical assistance through robot- Anomaly detection- Emergency call through Skype- Known information is sent by email- Robot control through Skype by doctor via voice commands

Emotion recognition●PCA projection●Logistic regression

Conclusion● Software is at least as important as hardware● Dynamic programming for real-life environment● Combining multiple approaches for higher 'confidence'● Improve on existing software if necessary
