“…Simulation helps the designer of a robotic system to determine an appropriate choice of robot and its workplace elements, including feeders, tools, grippers, fixtures and sensors. As the complexity of the system under investigation increases the role of simulation becomes more and more important, so that this is an important tool for car manufacturers simulate their plant layouts [7]. An ideal simulation process approaches reality so closely that the robot programs developed off-line can be loaded into the real robot controllers without having to correct them at the shop floor.…”

The benefits of robot simulation technology have been recognized by scientists and engineers, with applications ranging from simple robot path simulation to complete robotic cell layout simulation. Robot simulation is one of the essential elements of modern and agile manufacturing plants, as it allows to visualize and test a robotic system, even if it does not exist physically. High-growth industries and emerging manufacturing processes will increasingly depend on advanced robot technology such as robotic simulation. Robot path simulation is a very useful process to predict and pre-evaluate performance of robot programs generated off-line. This paper presents a simulation system where a relatively low cost and commercially available 3D CAD package is used as an interface to visualize/simulate preprogrammed robot paths. The developed system is intuitive and friendly, so that in a few minutes any user without knowledge of CAD and robot programming will be able to simulate robot paths and visualize it in a CAD environment. This way, this simulator can be useful for small and medium sized enterprises and for educational purposes. Three different experiments (simulation of robot motion/paths) are presented and discussed: a material handling task; a robot performing work in the footwear industry (shoes soles); and finally, the simulation of robot paths for a robot operating in a bending cell. The experimental results showed that the proposed system is flexible, easy to use and efficient. This paper also covers topics like how simulation makes robot programming easier, advantages and disadvantages of simulation in robotics, and the future trends in this field. Finally, the results of the experiments will be analyzed and discussed. The pros and cons of the system in relation to off-the-shelf robot simulation packages are analyzed.

Spring loaded balance system is a common method for designing the gravity compensation system of heavy-duty robot. In the design process of this system, the relevant parameters of the spring itself and spring loaded balance system’s installation position parameter have a great impact on the final compensation effect. This paper introduces a parameters optimization design method of heavy-duty robot’s spring loaded balance system. Based on the dynamics equation of heavy-duty robot, we built a mathematical model of the balanced joint with spring loaded balance system. The torque of balanced joint in this model and the relevant parameters of spring loaded balance system are the optimization goal and the optimization parameters relatively. Then we obtained the optimization result of spring loaded balance system’s parameters using optimization toolbox of MATLB. By the above method, we designed and optimized the spring loaded balance system of a 5-DOF articulated heavy-duty robot. Through the comparison of the result calculated by MATLB, the optimized spring loaded balance system greatly reduces the torque of balanced joint and the consumption of joint drive. Meanwhile, by this method, the optimized spring loaded balance system maximally improves the dynamic performance and service life of the heavy-duty robot.
