Vorpal Hexapod Activity: Hexapod Musician
From Vorpal Robotics
In this activity you will write a Scratch program to play an instrument.
- An inexpensive musical instrument such as:
- Children's Xylophone or Glockenspiel
- Inexpensive children's keyboard
- Bottles or glasses with different amounts of water in them, as long as you can keep them stable on the desk or floor!
- For items like Xylophones or water glasses, something to strike with, such as a mallet or stick.
- Tape to secure the mallet or stick to Vorpal's leg, or secure instruments to the surface so they don't move.
- Tape the striking mallet or stick (if necessary for your instrument) to one of Vorpal's front legs
- Position Vorpal in a known spot in front of the instrument. Mark the surface with little bits of tape to indicate where the legs should start.
- Using Scratch, program leg motions to play the instrument. At first just see what you need to do to strike individual notes.
- The teacher may suggest a tune to play, like "Happy Birthday" or "Mary Had a Little Lamb".
- First find the angles to hit individual notes, write those down. Then string them together to make a tune!
- Keep most of the legs on the ground at all times so Vorpal doesn't shift with respect to the instrument.
Vorpal Hexapod Quick Links:
- Try having several Vorpal Hexapods form a band! One could keep beat on a drum, another could play the Xylophone, yet another a keyboard instrument.
