IOT connected hospital

To keep doctors and nurses attending to corona victims safe and reduce their workload

Given the rate at which we are losing our frontline warriors - our medical staff, who are being exposed to the dangerous Coronavirus during treatment, it is important for us to ensure their safety. Already, there is a lack of medical equipment and staff and hence a lot of stress on health workers. On top of that are indisciplined patients and the highly communicable nature of the virus. Most hospitals are understaffed and to cater to many patients at once is difficult. This is where the system I propose comes in.
I wish to make a ground wheeled bot to attend to and monitor patients based on the PSoC 6 WiFi/BT Pioneer development kit and AWS IoT.

To attend to corona patients for even trivial tasks like providing them medicine or checking their temperature, doctors and nurses put themselves at great risk to attend to them. To prevent this, I propose a ground robot capable of locomotion inside a hospital environment and attending to patients and fulfilling some basic needs and even raising an alarm in case of an emergency.
The floor of the hospital would have to be marked with black tape to make lines for the bot to follow with its IR line detector module. The lines need to make a map of the entire ward with each bed given a pre-assigned identification ID. The instructions to the bot would be sent to it wirelessly over Wi-Fi(if the hospital has a connection) by the doctors or nurses through an app that connects to a web application based on Node-Red, from the comfort of their homes Through an AWS IoT Events script.
Instructions like checking the body temperature, giving medicines and essentials would be given through the app. 
The main controller for the bot would be based on the PSoC 6 Pioneer kit which would control the rear wheeled bot. Since, it is a health-critical application AWS IoT Greengrass would run coupled with AWS FreeRTOS would be run on it.
Also, the patient may summon the bot at any time, through a calling button on the bedside. As soon as the bot receives a signal to attend to a patient, it goes to the specific bed and wakes up the IR LED on the bedside with the help of the magnet attached on it, that sends a coded message corresponding to that bed. If the codes match, then the bot proceeds with further actions. This setup was chosen purposely to ensure data security which is a critical issue these days. Also the wakeup mechanism ensures that the PSoC 6 board which is capable of drawing less power during sleep mode may not drain the battery too quickly.
A panel of buttons would also be providesd on the bedside, through which the patient may ask for some essentials like water or call for medical staff. If the doctor wants to see the patient, the bot may also give audio and video footage with relevant peripherals on the Pioneer board. The instructions to the patient would be given through the Display shield on the board. The logged temperature data would be used to control the windows in the ward and the air-conditioning.
Also, the module mounted on the patient`s bed may also trigger emergency messages for the doctors and help in case of an emergency, taking sensor data from ventilators or other monitoring equipment. In such an emergency, if the attending doctor is not available on-site, he may initiate certain basic tasks through external plug and play modules that can be mounted on the bot for things like fluid injections, or tweaking settings of life-support modules  like ventilators till competent staff can attend. 
The application would keep track of all willing, active and competent doctors on the platform, who would be issued a notification if the doctor attending to that particular patient is not available(something like Ola and Uber). Enrollment would be on a voluntary and competency basis. This would help reduce the workload on doctors at hospitals where the number of patients...
