AGV - Automated Guided Vehicle System based on IoT

Automated Guided Vehicle (AGVs) is computer-controlled system; just another way to sort containers, move products from one location to another, manage short-term storage of items, and deliver them to assembly lines, shipping locations, and warehouses as needed.

The movement the vehicle is done with the help of high torque DC GEAR motor and L298 driver module and it is controlled by RFID reader as well over Wi-Fi operate IoT system. While a respective RFID tag is read at the start point the vehicle moves in the predefined path to the destination. Load cell is used to detect whether the AGV is over loaded. If in case over loading has occurred it give alter and a buzzer to indicate to the operator.

Every container on the vehicle bears an RFID transponder for its unique identification. Vehicles and containers are located in stations at different points in the work area, At the beginning the goods are loaded into the AGV the system checks for any overload if yes it sends an alert to the IoT operating system. If not, when the RFID tag is read the AGV starts to move from source to destination in the predefined path. If any obstacle is detected in the pathway, then also the alert message and buzzer is used to inform the operator. The AGV reaches the destination and goods get unloaded.

The operator can also control the vehicle over IoT system, TCP/IP network from any remote mobile/PC placed, from where the operator send them on their desire way online. As soon as a vehicle arrives at a branch point, a reader installed there detects the transponder and sends back its information to the operator .

(KL-114) RF Remote Controlled Dual Mode Robot for Multipurpose Task

This project propose a dual-mode robot that can be operated manually using a RF remote control and can also move automatically avoiding all the obstacles. The robot has some inbuilt intelligence to avoid obstacles by changing its path. It can be use in multiple applications like automatic vacuum cleaner. In such an application the vacuum cleaner will automatically clean the floor, or we can direct it using the RF remote while sitting relaxed on sofa.

The project design consist a RF based remote unit and at Robot side a microcontroller is interfaced to the RF receiver and motor drive circuit with obstacle avoidance sensors for robot movement. RF remote unit is built around encoder IC HT12E, 433MHz RF transmitter module and a few discrete components. Four Switches are interfaced with encoder IC for forward, reverse, left and right motions, respectively. When any switch, say forward, is pressed, the corresponding data is serially transmitted from DOUT pin through the RF transmitter module. A 9V battery is used to power this circuit. At the receiver end, this transmitted signal is received and decoded. The microcontroller unit compares the received code and drives the motors corresponding to the code received. Obstacle detectors detect any object in the way and intimate the microcontroller.

This robot is in manual mode by default. In manual mode, it can be directed by the remote. For each direction there is a dedicated button on the remote. When the robot encounters any obstacle, it stops moving forward. The robot will, however, be able to move in the rest of the directions. To make the robot work in automatic mode, press S1 and S2 simultaneously. In automatic mode, the robot will move in forward direction. If it encounters any obstacle, it will stop. To avoid the obstacle, the robot will automatically move a little back, turn to the right by 90 degrees, move forward, then turn left. After the obstacle is avoided, the robot will continue moving forward. To turn off the automatic mode, press S3 and S4 simultaneously. This algorithm can be further refined for different applications.

(KL-124) Border Security Robot using GPS-GSM System and Sensor Network

The ordinary border patrol system suffers from intensive human involvement. The major problem in protecting long stretches of borders is the need for large human involvement in patrolling. To monitor the border in real-time with accuracy and minimize the need for human support, multiple surveillance technologies, which complement each other are required.

The main objective of our project is to implement the general idea of boarder security robot with wireless sensor network architecture for border patrol system. Our Border security robot utilize the various sensors of network, A PIR sensor for human detection, a metal detector to detect the presence of explosives and an Ultrasonic sensor for obstacle detect.

Controlling the robot by using GSM Module is a most suggested mechanism for mobile robot which has the capability of changing directions for the long range distances. In our design, various sensor for detection and controlling method using robot is proposed. Upon detection by these sensors immediate SMS is sent to the authority’s mobile by using the GSM module. Then the user can control the robot by using GSM Module from remote location. The GSM Module also deals with a system of tracking the location of the robot using GPS and the GPS information is sent by the GSM module to authority’s mobile through a SMS which is read and then through a GSM device user can move and control the robot from any remote place.

This project can be further enhanced by involving the Mechanical control of robotic vehicle along with robotic arm with auto trigger gun and these also can be controlled from the remote station.

(KL-125) Wireless RF Remote Controlled Security Robot

This project is aimed to develop a robotic vehicle using RF technology for remote operation and sensors for security monitoring purpose. The robot is continuous move and monitor along with sensors for human motion sense and obstacle sense, up on sense of any human movement or obstacles, it sends alert to remote user through wireless RF transreceiver interfaced to a microcontroller and it alert with buzzer sound.

The project design involves an advance microcontroller interfaced to RF module and dc motor driver to drive the robotic vehicle. At the transmitting end using push buttons, commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end two motors are interfaced to the microcontroller where they are used for the movement of the vehicle. The RF transmitter acts as a RF remote control that has the advantage of adequate range with proper antenna, while the receiver decodes before feeding it to another microcontroller to drive DC motors via motor driver IC for necessary work. A PIR Motion sensor is used for monitor the human movement, up on sense any human movement it send interrupt signal to microcontroller and transmit alert signal to remote user through RF trans-receiver modules. Other sensor Ultrasonic sensor is used to monitor any obstacles upon sense robot stop and also send the alert signal to remote user. A buzzer is alarmed with different sound/tone train at the remote user side.

This project can be further enhanced using wireless night vision video camera. Further using DTMF technology, we can control the robotic vehicle by using cell phone. This technology has an advantage over long communication range as compared to RF technology.

(KL-126) Web browser Controlled Robot using Raspberry Pi

Internet technology provides a good way for us to develop an integrated computing network environment for the applications of different robotic systems. The concept of web based robots is new and it does not have the limitations of the range of operation. In traditional systems, the security forces need to patrol the remote areas in order to protect any illegal persons coming into our territory but it is not possible for them to patrol the whole area as it may be not possible to reach there. In traditional security ways, monitoring the areas is of only to a limited part. In such cases, we use the proposed robotic system which can be globally controlled from any remote place, whose working based on web browser using an advanced microcontroller (Raspberry pi 3).

The Raspberry Pi is a mini computer, which can be used in electronic applications or projects, and for many of the things that your desktop PC does, like browsing, text editing and games. The new and improved version, Raspberry Pi 3, is more powerful now due to the added advantage of having both Bluetooth and Wi-Fi . The special mention can be given to its on-board wireless capabilities, which works awesome with the default Raspbian operating system. The Raspberry Pi specific OS, Raspbian, makes Pi 3 easy to use when compared to standard Linux Os installations.

In this project, control of robotic unit is done from remote end with the use of Internet connected smart phone or PC. We are able to control the robotic movement in all direction like forward, backward, left, right and stop. A HTML Web page having GUI button panel is created, this web page can only be open with TCP/IP - user ID and Password through the internet operate smart phone or PC. DC motors and motor driver are being used for the movement of robotic wheels. IR sensor is used to detect obstacle in travelling path. The raspberry pi is powered through 3.3 volt of supply, which it takes with the help of linear regulator power supply fed through a 9-12 volt battery. DC Motors and motor driver are powered directly through the battery(9-12 Vdc). We use python programming to write the code into the raspberry pi.
