The present invention relates to the field of robotics, more
particularly, related to an automated nursing robot for sick/ill person.
BACKGROUND
[002] Nursing of infected patients especially Covid patients results in
exposure of nursing staff to danger of getting infected. Due to advancement in
robotics, there is no need to go to patient for performing nursing tasks such as
providing medicine and food as such task can be done remotely with the help
of technology. Many wired and wireless robots are designed for the same. In
wired robots meshing of wire may require to nursing staff to enter Covid
ward. Similarly for wireless robots range may create a problem. Hence, there
is a need to address this issue.
[003] US8311731B2 relates to a robot is provided with a motion control
unit that avoids collision between segments of the robot or between segments
of the robot and other objects. However, the cited document is only for robot
collision avoidance and is entirely different from the present invention.
[004] US20190329421A1 discloses a wireless tag detection and
localization by a mobile robot. However, the cited invention consists of the
RFID tags and sensor to roam within a building, and can detect violations of
security policies by objects is different from the present invention as it does
not address the issue completely.
[005] The present invention addresses the above shortcomings of the
prior art. However, the present invention is entirely different from the prior art
in terms of novelty and technological advancement.

SUMMARY
[006] The present invention discloses a self-sustained robot capable of
identifying the destination position and serves the patient as required. The
present invention can be mounted with any assembly like medicine feeder or
food tray to serve the patient.
[007] In one implementation, the robot is programmed with the grid of
the beds in Covid ward, which is referred by the robot to judge its destination.
[008] In another implementation, the entries are fed to the robot with bed
number and the type of nursing required like food or medicine as per nursing
requirement.
BRIEF DESCRIPTION OF THE DRAWINGS
[009] The foregoing detailed description of embodiments is better
understood when read in conjunction with the attached drawing.
[0010] Figure 1 illustrates a) the bed grid where the beds are numbered
from B1 to B12 and b) the bottom view of sensors mounting on the robot.
[0011] Figure 2 illustrates the flowchart of the present invention.
[0012] The figures depict an embodiment of the present disclosure for the
purpose of illustration and better understanding only.
DETAILED DESCRIPTION
[0013] Some embodiments of this disclosure, illustrating all its features,
will now be discussed in detail.
[0014] The present disclosure relates to a self-controlled robot which is
destined to reach the intended location and perform nursing tasks such as
providing food and medicines to the required patient. The present invention
consists of four sensors employed in the invention. The present invention is to
develop a robot which is self-control on the basis of bed grid system and
generally used in hospitals.
4
[0015] In the present invention, the identification of bed in Covid ward
uses line drawn on floor according to the bed grid.
[0016] In one embodiment, the beds are given numbering from B1 to B12
and can be customized as per the size of the room/ward in the hospital.
[0017] In the present invention, as per nursing requirement, the entries are
fed to the robot with bed number and the type of nursing required like food or
medicine.
[0018] In another embodiment, as the robot is moving straight, sensor
1(S1) and sensor2 (S2) guides the robot in moving straight.
[0019] In another embodiment, in case the robot reaches the cross section
i.e. any of the position 1, 2 or 3, all the sensors gives the signal to robot.
[0020] In another embodiment, as per the signal received, the robot can
take turn to reach the bed and serve the patient.
[0021] In another embodiment, the home position of the robot is identified
by having green color from all four sensors.
[0022] In another embodiment, the robot uses simple coordinate geometry
calculation method the reach to the destined position rather than complex
technology like machine learning.
[0023] In another embodiment, the present invention can be mounted with
any assembly like medicine feeder or food tray to serve the patient.
[0024] In another embodiment, the robot is programmed with the grid of
the beds in Covid ward which is referred by the robot to judge its destination.
[0025] In another embodiment, the preset invention employs color sensor
to locate home position.
[0026] In another embodiment, the robot with the pre-programmed grid
reaches the destined bed and does the intended task.
5
[0027] In another embodiment, the robot returns to the home position
(identified by green color) after completing the task where it can be
desensitized for further use.
[0028] In one of the embodiments, the present invention is very easy to
use.
[0029] In another embodiment, the present invention is easy to implement.
[0030] In an exemplary embodiment, the present invention provides the
solution for nursing the patients without any human intervention using simple
coordinate geometry calculation method wherein the entries are fed to the
robot with bed number and the type of nursing required like food or medicine.
[0031] Referring to figure 1 indicates a) the bed grid where the beds are
numbered from B1 to B12 and b) the bottom view of sensors highlighting
sensors S1, S2, S3 and S4 employed in the present invention.
[0032] Referring to figure 2 indicates the flowchart of the present
invention explaining the step by step process employed in the present
invention.
[0033] Some of the embodiments may be further upgraded based upon the
study performed further.
