The following video is of our robot and bells playing Mary Had a Little Lamb:

 

 

Since last week, the design of our structure has been modified to be more stable.

Here is a photo of the structure of how the bells are held:

 

Over the past week, we have established the final design of how the bells are positioned:



Use of KNex, four different note bells, duct tape

We have connected all four Servos to the Arduino and breadboard:

Each Servo is labeled with the corresponding bell note that it will control

 

Design Update

The following design adjustments have been made:

• rather than a flat surface base (such as a piece of cardboard), fasten bells to a K Nex structure
• AA batteries have been determined to be the best power source unique to this design
