Drones are air crafts without a human pilot . They work with the help of arduino board . There uses are expanding in commercial, scientific, recreational, agricultural and other applications such as policing and surveillance, aerial photography, etc.


This device is used for cutting grass, it basically runs on solar power. It uses revolving blades for chopping grass evenly and for a particular height. It also has a provision for adjusting heights , in order to cut the grass to a desired level . It uses the object sensors to change its directions. It also aids other process like cleaning, sweeping, etc. It is a multitasker.


Smart cars ,smart locks, smart home,etc are some of the emerging category called IOT. It’s goal is to provide users with smarter and more efficient experiences. This model consists of a rectifier circuit and a step down transformer in order to power up the arduino board. A set of relays are used for switching purpose .  The central component of the circuit is wifi . Wifi is used for connecting devices to internet . IOT has many real life applications like home automations, air and noise pollution sensors, weather forecasting, etc.


It is based on the technology of controlling the robotic arm in free space by leap motion. It uses a leap motion sensor that captures the sub millimeter movement of your hands and fingers, by using infra red light and camera. This device when connected to PC , has the ability to track your hands in 3D space and dispays it on the monitor. These are used in places where human interference is dangerous.


Inspired by the two wheeled self balancing personal transport vehicle, students of CJC invented segway. It uses an arduino board ,electric motors,accelerometer or gyro sensors. Gyro sensors enable to keep the robot in balance by measuring and reporting the velocity, orientation and gravitational forces of the robot. It integrates the idea of a self balancing platform that changes the speed of the motor based on the data received from the accelerometer.


It is a device which is efficient in solving the 3×3 rubics cube . It uses sensors and scanners to scan all the sides of the cube. It then functions according to the different algorithms dumped in it . It  is useful in solving the cubes.


It is a human controlled device and operates according to the signals received by it .These tanks are very compact and have a long durable life . They can be dropped from the air crafts on the battle field. As they reach the ground they cover themselves with the digital screens and become stationary like rocks which cannot be tracked by the radars or sonars. These then execute their work according to the signals received by them.
