Nearly 40 teams of undergraduates in robotics and mechatronics at the Ho Chi Minh City University of Technology and Education showcased their robots in Dancing Robot at their school. The machines were required to have an acceptable appearance, stand on their feet while moving their arms with ease to imitate human dancing. Each robot danced first based on programmed patterns and then created their own choreograph in reaction to a mixture of different musical genres like electronic music and bolero, a slow-tempo type. “We ourselves designed the robot, created sequences of dancing movements, ran tests, and failed six times before eventually finding the optimal structure for it,” said Nguyen Duc Cuong, a junior. “Now our robot can perform lots of dances virtually without falling down. The nice-looking decorations it wears make its dance steps more interesting.” Six robots were selected for the international dancing contest at the school by the end of this year. Tuoi Tre News
