# FPV Racing Drone

Team members:

- Griffin Descant (descant2)

# Problem
FPV Racing drones are usually very large and fast and thus require a large space. The Center for Autonomy Labs has a flying arena for lightweight drones such as the Crazyflie. However, the Crazyflie do not have a first person view.

# Solution
We propose to develop a small, lightweight FPV system for the Crazyflie in order to facilitate lightweight, small-space drone racing.

# Solution Components
## Power system
The system will draw power from the Crazyflie and use regulators to power each of the subsystems.

## Camera
A lightweight camera will be used to capture video from the drone.

## Transmitter/Receiver
A video transmitter on the drone will stream the video from the camera to a receiver connected to the headset.

## Video Processor
Microprocessors on the drone and at the receiving end will convert the camera data for transmitting and the received data back to video for the headset.

## IF LED Array
In order to track the location of the drone for the purpose of racing analytics, an infrared LED array will be attached to the drone to display a programmable pattern. This would allow the simultaneous tracking and differentiation of multiple drones in the future. This will be tracked using the labs Vicon motion tracking system.

# Criterion for Success
1 – The Vicon motion system should successfully track the drone using the IF LED array.

2 - The headset should receive a video stream of at least 30Hz.

3 – The Crazyflie should be able to maintain flight for 3 mins with the system running.

Recovery-Monitoring Knee Brace

Featured Project

Problem:

Thanks to modern technology, it is easy to encounter a wide variety of wearable fitness devices such as Fitbit and Apple Watch in the market. Such devices are designed for average consumers who wish to track their lifestyle by counting steps or measuring heartbeats. However, it is rare to find a product for the actual patients who require both the real-time monitoring of a wearable device and the hard protection of a brace.

Personally, one of our teammates ruptured his front knee ACL and received reconstruction surgery a few years ago. After ACL surgery, it is common to wear a knee brace for about two to three months for protection from outside impacts, fast recovery, and restriction of movement. For a patient who is situated in rehabilitation after surgery, knee protection is an imperative recovery stage, but is often overlooked. One cannot deny that such a brace is also cumbersome to put on in the first place.

--------

Solution:

Our group aims to make a wearable device for people who require a knee brace by adding a health monitoring system onto an existing knee brace. The fundamental purpose is to protect the knee, but by adding a monitoring system we want to provide data and a platform for both doctor and patients so they can easily check the current status/progress of the injury.

---------

Audience:

1) Average person with leg problems

2) Athletes with leg injuries

3) Elderly people with discomforts

-----------

Equipment:

Temperature sensors : perhaps in the form of electrodes, they will be used to measure the temperature of the swelling of the knee, which will indicate if recovery is going smoothly.

Pressure sensors : they will be calibrated such that a certain threshold of force must be applied by the brace to the leg. A snug fit is required for the brace to fulfill its job.

EMG circuit : we plan on constructing an EMG circuit based on op-amps, resistors, and capacitors. This will be the circuit that is intended for doctors, as it will detect muscle movement.

Development board: our main board will transmit the data from each of the sensors to a mobile interface via. Bluetooth. The user will be notified when the pressure sensors are not tight enough. For our purposes, the battery on the development will suffice, and we will not need additional dry cells.

The data will be transmitted to a mobile system, where it would also remind the user to wear the brace if taken off. To make sure the brace has a secure enough fit, pressure sensors will be calibrated to determine accordingly. We want to emphasize the hardware circuits that will be supplemented onto the leg brace.

We want to emphasize on the hardware circuit portion this brace contains. We have tested the temperature and pressure resistors on a breadboard by soldering them to resistors, and confirmed they work as intended by checking with a multimeter.
