Robo Server for food management services
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryNowadays world becomes more autonomous and does its work with less human interference. We have seen that the whole world suffered a lot from the COVID-19 pandemic in last two years meanwhile in most of the countries the situation of this pandemic becomes worst. In these destructive circumstances, the only solution to overcome the increasing infective rate of this pandemic among humans is to avoid human interactions. In this situation, in the food industry waiter robot technology plays a vital role. Robo server is basically a robot that works on the principle of line following robot. It serves food in restaurants like a waiter and is controlled from the kitchen. In this project, the robot follows the track from the kitchen area to the particular table, where the track is drawn on the floor with the help of a black tap. The information about choosing the desired table from the group of tables is provided by the RF controller, which operates from the kitchen. Also, if the robot faces any obstacle or hurdle in its path, then a buzzer or alert will be activated that helps the management of the restaurants to make sure the smooth functioning of the robot. Weight of 3 to 5 kg will be carried in its tray, at the destination table robot will be stopped and wait unlit the customer picks up its meal and move back to the kitchen when the wait is removed. Arduino UNO, IR sensors, IR Obstacle detection sensor, 4V 1.2Ah Rechargeable Battery, Motor driver L293D, RF transmitter, RF receiver and weight sensors are the major building blocks of Robo server. This project is an effective application in the field of industry, innovation, and infrastructure.
Project ObjectivesIn Restaurants the number of waiters to serve food are enhancing day by day which is not appreciable as we have already seen the consequences of gatherings in the Covid-19 pandemic. Thus our objective is to minimize the human interaction in restaurants through ROBO SERVER which will serve food to the particular table by Artificial Intelligence.
It will also enhace the economic growth and will play a important role in providing a healthy and safe outdoor environment for the adults and children as well.
Project Implementation MethodStep 1: Provide input of the table to be served from RF remote.
Step 2: While following the black line on the floor the robot travels to its desired table.
Step 3: If there is any hurdle in its path then a buzzer will be activated.
Step 4: After reaching that particular table the robot waits until the customer picks up its meal.
Step 5: After serving food to the table the robot will itself take the decision to move back towards kitchen (After the weight is being removed).
Benefits of the ProjectWe know that as the years are passing technological inventions are increasings and the robots are replacing the humans. In manufacturing industries, in production and in many other processes robots and automation is on progress. Thus our project has a substantial role In food and medical industry and in future it could also enter in transportation industry as well.
Technical Details of Final DeliverableFor particular number of tables there would be a specific distinctive path defined for each table.
Our Robot will be programmed to retrieve the information or input provided for a particular table. Input will be provided to the robot through RF transmitter which would be controlled from the kitchen (distant place from table). After the RF receiver gets the signal the robot will start working.
Motor driver L298 will give input to the motors and the motors will start working. With the help of IR sensors the robot will detect the black lined path on the floor and will go to that particular table of which the input has been received. While going on its path if any hurdle comes the robot will indicate it through the ultrasonic sensors used in it and then alarm will be activated.
After reaching to that particular table the robot will wait until the weight will be removed from the robot by the customer.
When weight will be removed the robot will return to its starting position.
Coding will be done in Arduino IDE software and will be uploaded to arduino (hardware).
