Tiivistelmä
The extensive use of mechanical tools does not only liberate human resources, but also greatly improves the overall work efficiency. Because the Nordic region is a famous supplier of timber in the world, it is even more essential to design a more efficient logging robot in order to accelerate the speed of cutting trees.
This thesis, through analyzes a full range of structural design and a comprehensive selection of components. It illustrates the details and key points of producing a type of robot from an idealization to actual production, as well as whether the actual design parameters will meet the actual needs (through simulation), which will build up to the automatic logging robot arm with a complete new design.
Through the calculation of the moment of inertia, torque, motor power, transmission ratio, strength (bending, yield, tensile) and safety factor, the design of the robot arm such as what material and machine elements should be used to build the robot arm is achieved. The requirements of the design like size and mechanical properties will be perfectly displayed on the actual robot arm.
