In this paper, we present a generic methodology for the synthesis of industrial robot applications with sensory feedback at the end-effector level. The presented methodology assumes an open controller architecture and leads to the creation of a library of modular and reusable entities, which can be used to build new systems based on the proposed architectural framework. The library facilitates the integration of new algorithms and it evolves as new modular applications are built. The library components belong to the control objects layer of the open controller architecture and implement functionality for sensor interfacing, sensor modeling, pattern recognition, state estimation and state regulation. The validity of the approach is verified by composing real industrial applications. The experimental results indicate the high quality of the developed systems. 相似文献

A PC-based open robot control system: PC-ORC 总被引:1,自引:0,他引:1
An open architecture manufacturing system pursues to integrate manufacturing components on a single platform. Therefore, a particular component can be easily added and/or replaced. In this paper, a modular and object-oriented approach for the PC-based open robot control (PC-ORC) system is investigated. A standard reference model for controlling robots, which consists of a hardware platform, an operating system module, and various application software modules, is first proposed. Then, PC-ORC system, which can reconfigure the control system in various production environments, is developed. The PC-ORC is constructed based upon the object-oriented method. Hence, it allows an easy implementation and modification of various modules. The PC-ORC consists of basic software, application objects, and additional hardware devices on a PC platform. Finally, by applying the proposed PC-ORC to a SCARA robot, the performance of the PC-ORC is examined. 相似文献

In this paper, we have applied genetic programming to generate an optimal architecture of neuro force controllers for robot
manipulators in any environment. In order to perform precise force control in unknown environments, the optimal structured
neuro force controller is generated using genetic programming with fuzzy fitness evaluation. After the architecture of the
neuro controller has been optimized for any kinds of environments, it can be applied for a robot contact task with an unknown
environment in on-line manner using its own adaptation ability. An effective crossover operation is proposed for the efficient
evolution of the controllers. The simulation has been carried out to evaluate the effectiveness of the proposed robot force
controller. 相似文献

复杂的作业环境和艰巨的作业任务使液压驱动型四足机器人对其伺服系统的精度、速度和力量均比一般机器人在普通情况下有更高的要求。为掌握液压驱动型四足机器人在多种路况下行走时各液压缸的受力情况以及液压系统内流量、压力的变化情况,需要对其虚拟样机进行机械动力系统和液压伺服系统的联合仿真,定性分析电液伺服系统位置、速度等被控对象的特性,并分析PID控制器在四足机器人伺服控制方面的特性与不足。针对传统控制算法在四足机器人控制存在的短板问题,设计了一种非对称前馈补偿模糊自适应PID算法,并利用物理样机进行了实际验证。实验结果为四足机器人电液伺服控制系统硬件、软件和控制算法的设计与优化指明了方向,还为研究四足机器人平稳步态控制策略提供了决策依据和数据支持。 相似文献

The structure of a flexible microprocessor-based controller for a low-cost robot for component handling is described. The robot demonstrates three degrees of freedom within cylindrical coordinate motion. One axis uses end-stop pneumatic actuation with the remaining two axes being actuated by specially designed hydropneumatic drives. By using hydropneumatic actuation and incremental encoder feedback, point-to-point positioning is provided through a real-time closed-loop control algorithm designed and implemented within the controller structure. Interactive programming aids have also been implemented within the control structure to allow operatives to describe robot handling tasks by using a shop floor oriented language. Both hardware and software for the controller have been developed in a modular form to increase its flexibility allowing the modules produced to be used for the control of other work-handling systems. 相似文献
