Agricultural Robots for a Sustainable Green Environment : A Review

The emergence of robots in agriculture exorbitantly boosted the productivity and output of agriculture in so many countries. It will reduce the dependency on fossil fuels, which in turn decrease the large levels of pollution caused by farm machineries. In addition, the usage of robots in agriculture decreased the cost of operation and preparation time of agricultural activities that will provide a solution to persisting problems faced by agricultural communities around the world like labor scarcity, Non-uniformity in yield, low rate of production and deficiency in throughput etc. Agriculture is a strategic industry that serves as the foundation for social stability and economic development. However, the global economic and social development is severely jeopardized by environmental deterioration, rapid population growth and shortage of resources. Agricultural Robotics is the impregnation of automation technology into bio environment such as agriculture, forestry, green house and horticulture etc. The intentions of this review paper is to validate the latest developments in the field of agriculture, Possible power sources and various sensors like global positioning systems (GPS), machine vision, dead-reckoning sensors, laser-based sensors, Accelerometers, inertial sensors and geomagnetic direction sensors. Lots of field work such as digging, harvesting, sowing, weeding and spraying operations have been performed by agriculture robots or agbots further, its performances are also enhanced in conjunction with technology.
