The Challenge:
The response time of emergency situations, like a heart failure, can be a big problem in sparsely populated communities, since a low number of ambulances covers these areas. To help these areas a number of stationary defibrillators has been placed around in the Danish communities. Unfortunately, in the fore mentioned areas there are quite some distance between neighbors. The result of this is that there can be far between the patient and emergency help, since there often only is the patient and one witness. The witness might only have time to make one phone call before it is necessary to perform CPR and therefore a third person would be needed to fetch the defibrillator and bring it back. So the problem description of our project was,” How can the time where an emergency patient is without a defibrillator be minimized”

The Solution:
First of all to make the solution manageable in the given time frame there where made some limits for the product. Instead of driving on the roads outside we limited the product to drive inside, the only major difference would be the navigation system and the obstacles. The product was also limited to be a driving vehicle and not flying because of the strict rules of autonomous drones.
Our prototype idea
Final prototype
The solution we came up with is an autonomous vehicle made by modifying a remote-controlled car and equipping it with a defibrillator. The vehicle utilizes a vision system to follow the road, and an indoor positioning system (IPS) to track and follow a specific route.

To make sure the vehicle doesn’t cause harm to people or materials when in response it has been equipped with ultrasonic sensors and a bumper which will make sure the vehicle stops if it is triggered. The ultrasonic sensors are also part of the obstacle avoidance system, where the car is able to drive past stationary obstacles a Lidar is also used as part of the avoidance system.

To avoid people standing in the way, the car has been equipped with sirens and emergency lights like an emergency response vehicle. The vehicle is fully autonomous after it has been started which can be done remotely via Wifi
Benefits of the NI platform
The reason we chose the NI platform is based on intuitive way the programming language is made, so that even newcomers in the programming world can make advanced and powerful programs. This comes from graphical interface, the large helpful community of the LabView forums and powerful build-in functions such as the Vision assistant, which makes complicated vision algorithms easy to build and implement. Coupling this with the ability to embed software in real-time onto the myRio, which in itself is also one of the main benefits of choosing the NI platform, creates an opportunity to make really incredible systems.
