Bicycle Shifting Indicator

This design, the Bicycle Shifting Indicator, does exactly what the name suggests: indicate when one should shift gears on their bicycle! This robot is used to make your life on your bike easier! Using a button sensor and modified cam design, the robot senses how many rotations your pedals make every 2 seconds. With this information, the robot either lights up red to downshift, yellow to stay in gear, or green to upshift.

At the end of a 2 week online, pre-college course called the Tufts Engineering Design Lab, we were tasked with creating a robot with all the coding skills we learned, and this is what I created! I recommend checking out my website for a full description and the code!

Note:

• This was designed for a Giant Talon 3, so adjustments to the design may need to be made for your bicycle
• Use some sort of lubricant between the cams and the button to avoid wear
• The robot was based off of a GoPiGo and Raspberry Pi
