探讨了一种埋弧点焊方法。在高频作用下,电弧在焊剂下引燃、加热并熔化焊丝与焊件,一旦焊丝端部熔化金属脱落过渡,电弧随之燃灭,在焊件上就形成一个光滑的焊点。用大约75A电流能成功点焊0.4mm厚的板件。 相似文献

This study has to do with a method for the intuitive programming of dual arm robots. A task oriented programming procedure is described for this reason, including the proposed dual arm robotics library and the human language. The robotics library aspires after human like capabilities and implements bi-manual operations. This intuitive programming framework is based on a service oriented architecture and is developed in ROS. The user can easily interact with a dual arm robot platform through depth sensors, noise canceling microphones and GUIs. The methods have been implemented in a dual arm robot platform for an assembly case from the automotive industry. 相似文献

The progressive miniaturization and customization of today's products has lead to increased demand for manual micro-assembly systems. Telepresence technologies provide a promising solution to manual micro-assembly through overcoming scaling barriers and achieving high accuracies, while offering flexibility and an intuitive human-controlled working environment. Guaranteeing such an intuitive environment involves the provision of adequate feedback information. Various physical sensor arrangements at the micro-assembly site are used to generate haptic feedback in the human-controlled environment. Non-physical or “virtual” sensors, although artificially generated, can also remarkably improve user intuition. For precise controlling and high fidelity feedback, telepresence environments also require a flexible communication platform between the human operator and the assembly site. 相似文献

Dual-arm robots provide efficient approach for automated execution of complex assembly operations. With bimanual-manipulation, a dual-arm robot can simultaneously control relative motion and interaction of assembly counterparts in a dexterous human-like manner. This requires, however, sophisticated programming and control algorithms for arms cooperation. This paper addresses the development of an advanced industrial dual-arm robot system with novel capabilities, such as easy and rapid commissioning, compliance control of bimanual interaction in all assembly process phases, as well as intuitive planning and programming. The robot can be leased and easily integrated in assembly environment sharing the same workspace with human workers. 相似文献

One of the challenges of computer aided styling (CAS) consists in rendering surface forces, which are generated by the interaction of modelling tools and workpieces. Moreover, designers miss the form of real modelling tools when using less intuitive devices for interacting with digital systems. This paper describes methods, which allow a realistic virtual prototyping by not only taking the form factor into account, but also the appropriate haptic rendering algorithms as well. 相似文献
