We are enrolled in the ENGR 103 Robot Symphony Class.

In this class, we are going to design an instrument that is controlled by a robot. The robot is computer-coded and tasked to perform certain functions.

The project requires us to design and build a robotically controlled instrument to play notes on command. At the end of the term, the entire class will perform as a group orchestra to play a piece that people will recognize.

We plan to use a xylophone in this project. Our initial ideas were to use balls to hit the keys on the xylophone. The xylophone would have to be tilted at an angle for the balls to roll off due to gravity. There will be a ball pit at the bottom and a conveyor belt mechanism to transfer the balls back up to the top so that they are ready for the next note. The balls will be released by a slot that will open on command. We were thinking of using a slight incline or a slide to point the balls in the right direction. The slide will move by a servo that will rotate on an axis. The conveyor belt will need to be continuously running in a loop, but we do not have any ideas on what motors to use for this yet.

Here is our initial sketch:
