Next Level of Hospitalisation Through Smart ICU

Intelligent health applications are being developed using automation technology to help patients by providing smart health solutions. The proposed research aims to create an intelligent automated hospital infrastructure capable of performing a variety of smart tasks in an Intensive Care Unit (ICU). Using a robotic arm on an autonomous robot, the developed system will make food and medicine more accessible. Furthermore, the robotic arm can be controlled locally by the patient’s paramedics. The proposed intelligent robot will keep track of the patient’s health by automatically monitoring vital signs like sleeping, stress, and discomfort. This proposed system is especially useful for diseases like covid-19, where close proximity can spread the disease.

This study used an LSTM-based neural network to classify EEG data and compared the results to those of other machine learning algorithms. On a self-generated dataset, the proposed LSTM network achieves 94 percent accuracy. Other machine learning models such as SVM and Multilayer Perceptron are compared to the results obtained (MLP). The intelligent navigation feature is also introduced, allowing the robot to move around the ICU independently. In addition, it can set up a video conference between the patient, the staff, and the family members. In the event of an emergency, the robot can automatically notify the staff and provide assistance to the patient via an intelligent chatbot.


The proposed system consists of two modules, the first one is bed and arms control system using EEG signal classification through a state-of-the-art LSTM deep learning architecture. Fig. 1 shows the workflow of the first module.

The second module is an autonomous wheeled robot that can autonomously navigate the hospital and read the patients’ vitals through an RGB camera frame using OCR and update nurses and doctors. The workflow of the second module is shown in Fig. 2. The robot has two robot arms to assist the patient in their daily life routine like drinking water, taking medicines, etc.


Three states of the art machine learning and deep learning classifier are used and evaluated on the self-generated dataset among all LSTM network that performs best. The design and implementation of three classifiers are described below one by one.


Because of their high generalization potential, SVM (support vector machine) has gotten a lot of attention and has been effectively implemented for a lot of image classification tasks. These

algorithms initially map non-linearly divided specimens into a higher (possibly infinite) dimensional space, then use the maximum margin research to identify a separating hyper-plane. The SVM maximizes the least length from the hyper-plane to the nearest training specimen in this higher-dimensional space.


In recent decades the neural networks outperform in classification and regression problems. MLP have three types of layers. The first one is the input layer which is used to get inputs from the environment. The number of neurons in the input layer is equal to the number of features from the environment. The second type of layer is hidden layers, acting as feature extractor layers. The number of hidden layers can be more than one. The third type of layer is the output layer. The number of neurons in the output layer is equal to the number of classes.


Recurrent Neural Networks (RNN) are neural networks that deal with sequential data to extract temporal information. The Sequential data can be textual, audio and video. LSTM produces the current output by using the previous information in the sequence. Furthermore, weights and biases for all nodes in the layer are the same. It uses the previous step’s input as well as the current input.


After analyzing the loss and accuracy graphs of three classifiers, it is observed that LSTM performs best among all classifiers because of its stateful features. It remembers the previous states and used them to calculate features at time t.


This research has facilitated the medical industry for diseases where close proximity can spread the disease, such as the covid-19 situation. This research work proposed an intelligent robot to assist the patients in ICU and the hospital’s rooms. It will assist the patients through the brain-computer interface (BCI) by understating the EEG signal using machine learning and deep learning algorithms.

This research compares the three state-of-the-art machine learning and deep learning algorithms and finds out LSTM performs best because it achieves 94.0% accuracy on a self-generated data-set. The intelligent navigation system is proposed to make the robot autonomous using the map, Kinect sensor, and other encoders and actuators. We Believe that it will be a valuable addition in hospitals, health care centers that can enhance the capability of modern health systems.
