Software for robotic simulation

The last few years have witnessed a large increase in use of computer graphics to simulate the robotic performance. The utilization of graphic simulation and programming has greatly enhanced the design, control, and productivity of robotic applications, especially in manufacturing. When designing and controlling robotic systems, computer graphics can be used to evaluate how the robot will react to and perform within the production environment before significant time, capital, and expense are incurred. Graphic simulation enables the designer not only to select the right robot but also to program it to perform the task in the most efficient way. The purpose of this paper is to review the recent advances in graphic techniques and to evaluate available software packages for simulating the motion of robots. The equipment associated with the software packages is also discussed.

Optimal design with the aid of randomization methods

Many design problems can be formulated in terms of a number of nonlinear equations and inequalities. A solution of such equations is called a design. In the present paper a method is given for the random generation of a large number of designs, which can be ordered according to some criterion. Using highspeed computer calculation, a large number of random designs is generated from which the designer can make a choice. A trend in selecting certain designs can be imposed: A requirement can be optimized or an optimal compromise between two or more conflicting requirements can be determined. An arbitrary number of variables can be specified. An interactive program has been written and implemented on a number of interactive computer graphics systems. Using the graphic functions, search areas in which the optimum is expected to lie can be modified interactively, thus increasing the speed of convergence. Information about the equations can be given either interactively or in a file, therefore equations can be given either interactively or in a file, therefore relieving the user from the task of programming. The program has been applied to the design of gear pairs, steam condensors, and bearings.

Region filling operations with random obstacle avoidance for mobile robots

The article presents a new topic in path planning for mobile robots, region filling. which involves a sweeping operation to fill a whole region with random obstacle avoidance. The approaches for global strip filling and local path searching driven by sensory data procedures are developed. A computer graphic simulation is used to verify the filling strategy available. The research was developed from the program for the design of a robot lawn mower. However, the solution appears generic. The significance is that a problem of wide application and generic solutions for general autonomous mobile robots have been developed.     

3D input for CAAD systems

It is often acknowledged that the main advantage of computer aided architectural design (CAAD) systems is that they can be used by architects to quickly and accurately evaluate alternative design solutions using a variety of performance measures which would be too time consuming to apply by hand calculation.To gain the full advantage of interactive CAAD requires the architect to use a computer terminal with graphic capabilities so that he can create and modify his design geometry in a form which can also be directly interpreted by the evaluate routines within the CAAD system. However, it is suggested that it is often difficult for the user of such conventional, graphic, CAAD systems to conceptualise the building being designed by only inspecting and manipulating drawings displayed on the terminal screen.This problem may be accentuated when building users who are not professional architects wish to use a CAAD system so as to participate in the design process.A computerised building block system (BBS) is proposed with which the designer can physically build a model of his design as he would if he was using ‘Lego’¹ blocks. Such a physical representation may allow him to evaluate many of the visual and spatial qualities of his design in a more direct way than could be achieved using computer graphics. However, because the electronic system can ‘read’ the arrangement of blocks and input this information into a computer, the user's design can be evaluated with the same performance measures that are used in existing CAAD systems.
