ADVANCED ROBOTICS IN DEFENCE AND MEDICAL APPLICATIONS

Abstract

Development of Swarm Bot for Defence and Medical Application Design of Swarm bot is an initiative towards the synchronized performance of multiple bots as a total system consisting huge numbers of plain real-time bots. It is observed that an expected groupwise behavior is expressed from the interactions between the bots and the master device. The head posture movement is used to send the signal from the master device to communicate the slave devices. This methodology has come out in the field of artificial swarm intelligence, as well as the bio-inspired researches of insects and other fields in nature with the occurrence of swarm behavior. This process depends on the master-slave concept to operate the whole system. The wireless communication utilizes the SPI (Serial Peripheral Interface) protocol with radio waves in the range of 2.4-2.5 GHz. The ISM (Industrial Scientific Medical) band is used for the communication purpose. Development of Verticle Climbing Camouflage Surveillance Bot Scientists are trying to make vehicles that can move through both vertical and horizontal planes simultaneously for a long time. Moving against gravity makes it very difficult because of wheel spin in a steeply inclined surface plane. In this paper, we are dealing with the design and development of a WI-FI controlled bot that can move on both horizontal and vertical surfaces. The air suction technique is used to hold the bot on a vertically inclined surface. This paper presents the design and development of a wall climbing bot using an ESP32 CAM microcontroller. The wall climbing feature is achieved by using a 2200kv BLDC motor and 600 mm propeller. When the propeller is rotated using the BLDC motor, the propeller sucks the air underneath the robot, creating a vacuum. As a result, outside air pressure works on the robot and makes it stick to the horizontal surface. The robot`s movement is done by using 4 100 RPM dc motors. The motors are connected to the ESP32 microcontroller via motor driver L298N and can be manually controlled using any ESP32 Android/IOS mobile application. We have used the TCS3200 colour sensor and RGB LED lights to change the colour of the body as per the surroundings. The robot can be used for any surveillance purposes from general surveillance purposes to surveillance of hostile areas.
