**Problem**

American football is a sport comprising two teams of eleven played on a field of 120 yds by 53 and ⅓ yards. One team attempts to either score touchdowns or field goals by either passing or running the football, an oval ball. The offense, or the team attempting to score the ball, has four downs to move ten yards from where they started. If they accomplish this goal, they get a new set of downs based on where they were stopped. This is decided by the referees, specifically the line judge, and is done through sight. This has some obvious issues, such as the accuracy of the referee in question. In this day and age, when other sports are able to do away with much of the inaccuracy in deciding scoring, we believe that there should be a solution to the most important part of football and the subjectivity surrounding it.

**Solution**

Sensors in the football will be able to provide real-time data and will have the ability to publish the data to remote servers. The data will include 4 key data measurements including geolocation, pressure, acceleration and gyroscope sensors which will allow us to track free-fall and impact during game play, as well as its precise location. We also want to measure the speed of throws, grip strength of the person throwing and catching. The final part is using some sort of indicator to make sure without a doubt that the requirements have been met for either a new set of downs, or touchdown.

**Subsystem 1:**
_Sensor suite_

This subsystem consists of a 9 axis motion sensor(accelerometer, gyroscope, magnetometer), GPS, and pressure so that we can track metrics of different plays and throws while simultaneously always knowing where the ball is
Components:
ESP32 Microcontroller
6 system ICM-20602
9 system BMF055
GPS system using ESP32 UltraWideband technology with 3 anchor points to track location down to the centimeter. (DW1000)

**Subsystem 2:**
_Power and Charging_

Lithium ion battery that we can charge using a power strip
Components: PRT-13851 Lithium Ion Battery and Charger

**Subsystem 3:**
_Actuation_

Variable leds that light up depending on downs, out of bounds or touchdowns
Components: LEDS Grove - Variable Color LED
Green for touchdown
Blue is for passing the down marker.
Red is for out of bounds

**Criteria For Success**\
Checkpoint 1: We want the tracking system enabled to check positioning on the football field\
Checkpoint 2: include the accelerometer and gyroscope tracker\
Checkpoint 3: air-pressure sensor to track pressure of the space within the ball \
Checkpoint 4: Ensure general weight and size parameters conform with NFL standards

Smart Frisbee

Featured Project

The idea of this project would be to improve upon the 395 project ‘Smart Frisbee’ done by a group that included James Younce. The improvements would be to create a wristband with low power / short range RF capabilities that would be able to transmit a user ID to the frisbee, allowing the frisbee to know what player is holding it. Furthermore, the PCB from the 395 course would be used as a point of reference, but significantly redesigned in order to introduce the transceiver, a high accuracy GPS module, and any other parts that could be modified to decrease power consumption. The frisbee’s current sensors are a GPS module, and an MPU 6050, which houses an accelerometer and gyroscope.

The software of the system on the frisbee would be redesigned and optimized to record various statistics as well as improve gameplay tracking features for teams and individual players. These statistics could be player specific events such as the number of throws, number of catches, longest throw, fastest throw, most goals, etc.

The new hardware would improve the frisbee’s ability to properly moderate gameplay and improve “housekeeping”, such as ensuring that an interception by the other team in the end zone would not be counted as a score. Further improvements would be seen on the software side, as the frisbee in it’s current iteration will score as long as the frisbee was thrown over the endzone, and the only way to eliminate false goals is to press a button within a 10 second window after the goal.
