Abstract

According prognosis of FAO(Food Agriculture Organization of United Nations) taking a study made in 2012, due to the average incoming for farm products, production should increase 1.1% per year in the period current - 2050 with the intention of feeding the increasing population. This requirement leads companies of agricultural industry to seek greater productivity and efficiency simultaneously, aiming cost reduction. In this scenario one of the important parameters is the pest control, which stands as one of the main strategies for improving yield of grain per area. In grain crops like such as soybeans, corn, cotton the difficulty of monitoring the plantations it is due to the extension of properties, so the pests can only be perceived after spread over a considerable area. For a better monitoring of plantations robots can be used, they can get around efficiently on rough terrain and do pest wakefulness. In this scenario we can apply Rovers, which aim to have autonomous navigation, technologies embedded in it allow for a precise localization, the prevention for obstacles and construction of maps in terms of changes in the environment that it is. This project will analyze some existing type of Rovers, and will be modeled the rovers ExoMars 3 Bogie and Curiosity using CAD software (Computer Aided Design) and it will be simulated to evaluate its performance along with tests in controlled environment.
