The coastal area beaches are main attraction for tourism, so in attracting tourist the beach must be kept clean. For the purpose of cleaning the beach, some cleaning machine must be used so we have manufactured a solar powered beach cleaning machine which is helpful in cleaning the beaches. The motor is responsible for driving mechanism of conveyor. The strainer attached to the conveyor will collect the wastage from the surroundings and transferred to storage bucket through conveying belt. As today’s era is moving towards being digitized and automated with a great speed, the youth want everything very easily and smart. The main aim of the project is to reduce the man power, time consumption for cleaning the beach. In this project we have automated the operation of beach cleaning with help of a motor and chain drive arrangement.

The utility model relates to an electromagnetic gear shift automatic speed changing device for a machine tool. There are disclosed an automatic gear change control apparatus for an automobile and a method of controlling such apparatus. A rotational output of an internal combustion engine is connected to drive wheels of the automobile and a load device. When a gear shifting-up of an automatic transmission is to be effected, the load applied by the load device is increased, or the load is connected to an output rotation shaft of the engine via a selectively connecting device, thereby reducing the rotational speed of the output rotation shaft of the engine to a required level. In our project, three electromagnetic coils are coupled to the gear rod of the two ends. The ultrasonic sensor is used to sense the wheel speed and this signal is given to the microcontroller unit. The microcontroller is activate the relay depends upon the vehicle speed. There are four relays are used, one for freely movement, second for Level 1 gear, third for Level 2 gear and another one for Level 3.

In modern era, opening and closing of doors is always a tedious job, especially in places like shopping malls, hotels and theaters where a person is always required to open the door for visitors. This project proposes a system of automatic opening and closing of door by sensing any body movement near the door. This is achieved with help of either sensor or switch control as per requirement. The door open/close signal is fed to a micro controller to operate a door motor through motor driver IC. When a body approaches within the operating range of the sensor, it sends a logical command to open the door. The door automatically closes with a fixed time delay.

Solar Powered River Cleaning Mechanism collect the floating garbage and solid waste from the water surface and collect it into its floating bin. It can be programmed, scaled up to any size and can operate remotely. In this project we have fabricated the android, remote or GSM messaging based operated solar power river cleaning machine. The main aim of the project is to reduce the man power, time consumption for cleaning the river. In this project we have automated the operation of river cleaning with help of a motor and chain drive arrangement. The work has done looking at the current situation of our national rivers which are dump with crore litters of sewage and loaded with pollutants, toxic materials, debris etc. The government of India has taken charge to clean rivers and invest huge capital in many river cleaning projects like “Namami Gange”, “Narmada Bachao” and many major and medium projects in various cities like Ahmadabad, Varanasi etc. By taking this into consideration, this machine has designed to clean river water surface.
