Round 2 | Devpost

Inspiration

As technology evolves, athletes are increasingly in a position to benefit from these advances and improve their skills. Due to challenges, athletes are sometimes not able to physically be present in a gym with a trainer. Round 2 enables them to continue to train using our device, anywhere, anytime.

What it does

Round 2 measures the acceleration of the user's punches, and displays the intensity and type of punch on a screen in front of the user. It also provides a record of the maximum intensity for reference, to motivate the user to continue to improve.

How we built it

We used an accelerometer to measure the acceleration of each punch, and an ESP32 to communicate between the accelerometer and the computer. We processed and displayed this acceleration data in an interface using Processing.

Challenges we ran into

Initially, we were going to use Bluetooth to connect the ESP32 to the computer in order to make our technology wireless. However, we could not maintain a stable connection. Thus, with the time constraints we had, we decided to instead connect the board to the computer via USB. We also were not able to 3D print our wearable wrist attachment, causing us to change plans and instead use velcro to secure the device we well as customize the attachment size.

Accomplishments that we're proud of

We are proud of the accuracy of the program to detect the type and power of each punch. We are also proud of our engaging way of displaying the data.

What we learned

We learned how to use an accelerometer, ESP32, and Processing. We also learned soldering and wire stripping.

What's next for Round 2

We would like to extend Round 2 to make it wireless, power the device using batteries, build better protection around the device, add physical speakers to provide more motivation to the athlete, and add more features such as heart rate monitoring to provide further information about the workout.
