We named our robot “Minnie Fay,” and she can dance like a ballerina. We have programmed her to play some classical music and dance along. She can turn around, open/close her arms, and move each of her legs separately.
We use a large EV3 motor to turn a turntable that attaches to both her body and her body-movement motors.
The body-movement motors are each EV3 medium motors: one medium motor facing up to turn a worm gear that opens and closes her arms, and two medium motors connected to piston-like mechanisms to raise her legs to multiple heights.
We also created a “record player” using a color sensor and touch sensor. Once the touch sensor is pressed, the color sensor will detect the color of each “record” placed underneath the sensor. The program plays a specific song and dance, depending on the color of the record the user selected. The red disc plays “Tea” from Tchaikovsky’s The Nutcracker. The green disc plays “Dance of the Sugar Plum Fairy” from Tchaikovsky’s The Nutcracker.
We have already programmed two songs and plan to add more! We loved making this robot because both ballet and robotics are things that are important to us. We hope to use this robot to inspire other girls to get excited about STEM and robotics.
