Sanitizers are playing a major role in the covid crisis by allowing for waterless sanitization of hands. Sanitizer dispensers too require a hand or leg press. So to ease the task and promote use of sanitizers. I have develop an automated contactless sanitizer dispenser. This machine makes sanitizer dispensing fully automatic with sensor based sanitizer dispensing.

The AIM behind making this device is that as the rainy season approaches, the government starts cleaning the canale and people have to go down inside the canale for this work. So my robotic device is designed to clean the lake and protect people from dirt and disease.

I am introducing a Battery Based Crop Cutting Machine that is fabricated with very simple mechanisms at a very low cost. Cutting of crops is one of the important agricultural operations which demand a considerable amount of Labour. The availability and cost of labour during the cutting season are the serious problem. The Shortage of labour during harvesting season and vagaries of the weather cause great losses to the farmers it is therefore essential to adopt the mechanical methods so that the timeliness in cutting operation could be ensured.

Human lungs use the reverse pressure generated by contraction motion of the diaphragm to suck in air for breathing. A contradictory motion is used by a ventilator to inflate the lungs by pumping type motion. A ventilator mechanism must be able to deliver in the range of 10 – 30 breaths per minute, with the ability to adjust rising increments in sets of 2. Along with this the ventilator must have the ability to adjust the air volume pushed into lungs in each breath. The last but now the least is the setting to adjust the time duration for inhalation to exhalation ratio.

Municipal solid waste is increasing annually, primarily because of the rapid population growth and lifestyle developments. This results in millions of tons of m.
