LabHW7: Flipper

Description:
The goal of the assignment was to explore using the servo motors and to make a crawler.
I partnered up to make a two servo motor design. The original goal was to make a flipper. One servo motor would flip the device 180 degrees. This would place the device in the position for the second servo motor to flip the device again.
We tried to design a device that would be self-contained and house the Arduino with independent 9V power source.
However, as we designed the device, we discovered that the servo motors did not have enough torque to push the device up and over with the added weight of the electronics and battery. Also, it was a challenge to put everything in place in a self-contained device.
 
Components Used:
1- Breadboard
1- Arduino Uno
1-  9V Battery
1 USB interface cable to Arduino
2 servo motors
Various spare wood for container.
