In recent days, the continuous use of non-renewable energy sources has resulted in global energy crisis and created in need of an alternative energy source. Solar energy with the features of being clean, reliable, sustainable, environment friendly, abundant is considered as a substitute for alternative energy source. The selection of appropriate machine drive plays a vital role in reliable and enhanced performance of the system. Solar based motorized fruit and vegetable harvesting device has helped farmers to overcome all the problems like unavailability of labours, damaging of fruit because of hand touching or picking etc. The design of solar based motorized fruit and vegetable harvesting device insisting of dc motor couple with blades helps to cut the pit of the fruit or vegetable during harvesting. The speed of the motor to be varied by using speed driver, as different fruit or vegetables need different speed based on the strength of the pit. The device also consists of an expandable stick which has a push button which can be used to adjust the length of the stick for the required height because the fruits are at found at different heights. With use such a device farmers can harvest faster than previously used manual harvesting methods. The solar based motorized fruit and vegetable harvesting device must be designed and developed to overcomes the abnormal noise. The proposed device is to be simulated using MATLAB tool and the hardware prototype module is to be realized to runs the device with adjustable variable speed, suitable for the sustainability and adaptability with the social concern. The testing needs to be carried out for the effective results with the development of a test bench.
