BACKGROUND OF THE DISCLOSURE
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] At least in the Indian context, lanes are typically printed manually on roads, wherein a first person pushes a lane printing machine and a second person is needed to control flow of thermoplastic fluid (liquid) that is stored in a container in the machine to print it on the road. A third person is also needed for walking in front of the machine with a thread that keeps the lanes in a straight line. Even in other countries, there are many machines that can partially automate the process, but they tend to be very bulky, large in size, and costly to the tune of at least around INR 30 Lakhs.
[0004] There is therefore a need in the art for a gesture controlled robot to print lanes on road that overcomes the above issues and is compact, cost-effective, reduces manual intervention, and has higher accuracy during the printing action.

[00044] FIG. 1 illustrates an exemplary constructional architecture of the proposed gesture controlled robot in accordance with an aspect of the present disclosure.
[00045] With reference to FIG. 1, the present disclosure relates to a gesture controlled robot to print lanes on a road using a liquid, said robot comprising: a transmitter (100) comprising a microcontroller (102), an accelerometer (104), an encoder (106), and an RF transmitter (108) that are configured such that when the robot is powered on, said accelerometer (104) is continuously monitored to generate data based on orientation of the accelerometer (104), said data being captured by said microcontroller (102) and transmitted to said encoder (106), wherein said data received by the encoder (106) is converted into serial data and transmitted by the RF Transmitter (108); and a receiver (200) comprising a RF receiver (202) that receives the serial data from the RF transmitter (108) and transmits said received serial data to a decoder (204), wherein the decoder (204) converts the received serial data into parallel data, said parallel data being transmitted to a motor driver (206) in a manner such that, based on the parallel data, movement of encoder motor (208) that is operatively coupled with the motor driver (206) is controlled.
[00046] In an aspect, robot of the present disclosure is a wireless operated robot.

Transmitter End
[00047] In another aspect, the microcontroller (102) can be an Arduino Uno based open source microcontroller board. In an exemplary aspect, the microcontroller board can be based on Microchip ATmega328P microcontroller, wherein the board can be equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The board can be configured to have, for instance, 14 Digital pins, 6 Analog pins, and programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable. It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts.
[00048] In yet another aspect, the accelerometer (104) can be a MPU6050 sensor. In an aspect, function of the accelerometer is to sense orientation of users’ wrist, wherein the accelerometer measures acceleration including acceleration due to gravity 'g' as well. The accelerometer (104) can be configured to sense orientation of the users’ wrist by measuring component of 'g' in any particular axis. Due to tilt of hand, X and/or Y axis' angle with vertical changes and hence a component of 'g' acceleration acts upon them as well which can be measured and thus indicates the orientation of the hand. In an exemplary and non-limiting aspect, the accelerometer can measure up to 3g of acceleration and can be interfaced with the microcontroller (102) by connecting its axis pins to Analog pins of the microcontroller (102). During its operation, the accelerometer can output voltage values proportional to acceleration. In an aspect, the accelerometer (104) can be connected to the microcontroller (102) and can be attached to the palm of a user/entity/person. The outputs voltage can range from 0 to Vcc (Applied voltage usually 3.3V) and can be read by the analog pins of the microcontroller (102). In an exemplary instance, for a user, values in range from 0 to 1024 (10-bit ADC) can be obtained. Different orientation can be configured to yield a different analog value for each axis, which is then mapped to different robot movements.

Receiver End
[00049] In an exemplary and non-limiting aspect, motor driver (206) can be a RC motor driver such as L298N that can be an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 package. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic level sand drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs can be provided to enable or disable the device independently of the in-put signals. Emitters of the lower transistors of each bridge can be connected together and the corresponding external terminal can be used for connection of an external sensing resistor. An additional supply input can be provided so that the logic works at a lower voltage.
RF Transmitter Receiver
[00050] RF transceiver module (comprising RF transmitter (108) and RF receiver (202) can be configured to work in a pair so as to send and receive data. A transmitter (108) can only send information, and a receiver (202) and can only receive it, and therefore the data can always be sent from one end to another and not the other way around. The transmitter (108) (also interchangeably referred to as transmitter module (108) can include three pins namely Vcc, Din and Ground. The Vcc pin can have a wide range input voltage from 3V to 12V. The transmitter (108) can, in an exemplary instance, consume a minimum current of 9mA and can go as high as 40mA during transmission. The center pin can be the data pin to with the signal to be transmitted is sent. This signal can then be modulated using ASK (Amplitude Shift Keying) and then sent on air at a frequency of 433MHz (only an exemplary embodiment). The speed at which it can transmit data can be around 10Kbps. The receiver (202) (also interchangeably referred to as receiver module) can include four pins namely Vcc, Dout, Linear out and Ground. The Vcc pin can be powered with a regulated 5V supply. The operating current of this module can be less than 5.5mA. The pins Dout and Linear out can be shorted together to receive the 433Mhz signal from air. This signal can then be demodulated to get the data and can be sent out through the data pin.
[00051] An RF module (radio frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly. This wireless communication may be accomplished through optical communication or through radio frequency (RF) communication
Encoder Decoder
[00052] In an exemplary and non-limiting aspect, encoder (106) can be HT12E and can be used to encode data for RF Transmitter (108), whereas decoder (204) can be, for instance, HT12D that can be used to decode data received by the RF receiver (202). The Encoder ICs can be series of CMOS LSIs for Remote Control system applications, and can be capable of encoding 12 bit of information which consists of 8 address bits and 4 data bits.
[00053] In another aspect of the present disclosure, the receiver (200) can be positioned on the robot, said receiver (200) being operatively coupled with the encoder motor (208) (also interchangeably referred to as rotary encoder).In an aspect, the rotary encoder (208), also interchangeably referred to as a shaft encoder (208), can be an electro-mechanical device that converts angular position or motion of a shaft or axle to analog or digital output signals. In another aspect, the encoder motor can be configured to control movement of the robot in a manner such that said robot moves in a straight line and does not move left or right.
[00054] In yet another aspect, the robot can include a container (210) that stores the liquid, said container being operatively coupled with a sprayer (222) that in turn is connected to a switch that controls flow of the liquid on the road, and wherein said sprayer (222) prints the lanes on the road.
[00055] In an aspect, the robot can include a container (220) that facilitate movement of the robot.
[00056] In another aspect, the robot can further include a servomotor that is a rotary actuator or linear actuator and allows for precise control of angular or linear position, velocity and acceleration. The servomotor can include a motor coupled to a sensor for position feedback. The servomotor can, in an exemplary aspect, also require a controller.
[00057] FIGs. 2A-2F illustrate exemplary views and representations of the proposed gesture controlled robot in accordance with an aspect of the present disclosure.
[00058] As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other or in contact with each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously. Within the context of this document terms “coupled to” and “coupled with” are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[00059] Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refer to at least one of something selected from the group consisting of A, B, C ….and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[00060] While some embodiments of the present disclosure have been illustrated and described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
