Abstract

The people in rural areas of Karnataka and Kerala mainly depend on agriculture for their livelihood. The main crops grown are Arecanut and coconut.
For harvesting the nuts, and for spraying and applying insecticides on the crown, skilled labourers have to climb manually up the tree. Such a process looks easy, in reality it is a laborious and dangerous task. It requires skill to climb a arecanut tree. Skilled arecanut tree climbers have become scarce and farmers are finding it difficult to harvest ....etc

Remote controlled screw jack is a modified form of the most commonly used screw jack. It uses the engine as a source of energy to lift the object and the gearbox is used to control the lifting jack. In this project, the usual motorized cylinder jacks is modified by adding additional rings in the Center to capture timing belt assembly.V belt pulley is added to the output shaft of a 12v DC motor the entire structure and Assembly is held in position by a angle iron Assembly. The entire project is managed by supply 5a.

Screwjack is controlled by t ....etc

A compressed-air vehicle (CAV) is powered by an air engine, using compressed air, which is stored in a tank. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot expanding gases, compressed-air vehicles use the expansion of compressed air to drive their pistons. One manufacturer claims to have designed an engine that is 90 percent efficient
Compressed-air propulsion may also be incorporated in hybrid systems, such as with battery electric propulsion. This kind of system is called a hybrid-pneumatic electric pr ....etc
