Development of hospital steward robot

Project Title

Development of hospital steward robot

Project Area of Specialization RoboticsProject Summary

It  is  a  robot  which  will  guide  visitors  and  patients  to  the  different  paths  of  the  hospital.It  will  work  on  the  principle  of  line  following  robot.It  will  also  work  as  a  doctor  assistant.When  a  new/uneducated  people  visit  hospital,they  don’t  know  the  way  to  their  desired  destination.This  robot  will  help  those  people  and  improve  the  management  of  the  hospital  and  also  will  ease  the  patients  and  save  time. It  will  also  measure  the  Blood  Pressure  and  the  Temperature  .

Project Objectives

• To design compact and usable Steward Robot.

• To provide a solution by constructing a low cost robotic system.

• Easily accessible commercially 

           with lower costs.

• To help and guide visitors/patients in 

            finding their desired destination.

     

• To make a low-cost steward Robot 

            guiding visitors/patients.

Benefits of the Project

BENEFITS

• When a new/uneducated people visit hospital , they don’t know the 

      way to their desired destination.

• This robot will help those people and improve the management of the  hospital and also will ease the patients and save time.

• It will also measure BP and Temperature of Patients

• This cheap robot will be affordable by every hospital

Technical Details of Final Deliverable

TECHNICAL DETAILS

LM 298

This dual bidirectional motor driver is based on the very popular L298 Dual H-Bridge Motor Driver IC. This module will allow you to easily and independently control two motors of up to 2A each in both directions.

It is ideal for robotic applications and well suited for connection to a microcontroller requiring just a couple of control lines per motor.

ARDUINO

The Arduino Uno board is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM outputs, a 16 MHz ceramic resonator, an ICSP header, a USB connection, 6 analog inputs, a power jack and a reset button. This contains all the required support needed for microcontroller.

LM 324

The LM324 operational amplifier IC can be worked as a comparator. This IC has 4 independent operational amplifiers on a single chip. This a Low Power Quad Operational Amplifier and it has high stability, bandwidth which was designed to operate from a single power supply over a wide range of voltages.

LM741

IC 741 mainly performs mathematical operations like addition, subtraction, division, multiplication, integration, differentiation etc. IC 741 has three stages such as differential input, gain, and push-pull output. Pin 1 and 5 are “offset null” or “balance” terminals. The op amp is nothing but a differential amplifier.
