A falta de uma gestão adequada dos resíduos sólidos urbanos (RSU) tem provocado ao longo dos anos nos Municípios com menos de vinte mil habitantes, diversos prejuízos nas áreas da saúde pública, equidade social e conservação ambiental, além de impactos significativos na ordem econômica em diversos segmentos de atividade. Dentro deste contexto, é necessária a efetiva implantação das diretrizes que preconizam a Política Nacional

DIAGNOSTIC AND PROGNOSTIC FOR THE MUNICIPALITY OF SANANDUVA/RS ABSTRACTLack of proper management of municipal solid waste (MSW) has resulted over the years in the municipalities with less than twenty thousand inhabitants, many losses in the areas of public health, social equity and environmental conservation with significant impacts on economic order various activity segments. Within this context, the effective implementation of the guidelines that prioritize the National Policy on Solid Waste is required. Thus, the objective of this work was to make the diagnosis and prognosis for the management of municipal urban solid waste (MSW) in the municipality of Sananduva/RS, and as the proposal of new MSW management methods can contribute to the reduction and proper disposal of RSU.
This article introduces or designs and practices a Gantry pneumatic robotic manipulator for greenhouse automation. The prototype was built on the reduced model for sowing and harvesting vegetables using the familiar concept of agriculture. Low-cost robotic handlers can contribute to improved working conditions in family farming and enable strategies to diversify agricultural activities for low-income families. The system has two degrees of freedom, was mounted on a metal workbench using cylinders and specially manufactured guided cable actuator. The control system includes nonlinear compensations of the servo valves used. Functional tests used step input electrical signals (-4 V to +4 V and -8 V to +8 V) using open loop circuit for robot pressure and positioning control. The results obtained are important for perfecting the robotic manipulator for family farming applications.
