The development of automation in construction has been restricted by the variety of construction materials used, variable
circumstances, and difficulties in the quantitative management of the construction process. Curtain wall, however, can be
considered a relatively standard material compared to other construction materials. In this study, we analyze the current
process of curtain wall installation and investigate the potential of an automated system combining a commercial excavator
and a 3-DOF manipulator. This automated system has the adaptations necessary to work with any type of commercialized excavator.
Therefore, workers need to transfer only the 3-DOF manipulator portion of the system when they move to other construction
sites. This paper investigates experimental trials involving the proposed system at construction sites to determine its performance,
working time, and efficiency. Results from this study were analyzed and further research options outlined. 相似文献

为解决爬壁机器人在船舶货舱清洗过程中多壁面过渡的问题,该文设计了一种具有壁面自适应能力的磁吸附爬壁机器人,其包括磁吸附机构、自适应清洗机构和行走机构。该文首先通过建立机器人壁面过渡时的力学模型,得到机器人磁吸附力的分布特点,并据此设计出一种弧形磁吸附机构。然后利用 ANSYS Maxwell 3D 软件对该机构磁吸附力的分布进行优化,以满足壁面过渡的需要;此外,还在机器人前端设计了一种自适应清洗机构,通过对该机构的结构原理进行分析和实验,验证了清洗机构也具有壁面过渡能力。最后通过模拟船舶货舱壁面的实际特点,对机器人样机进行壁面过渡综合实验,完成了机器人舱底过渡行走实验和舱顶过渡行走实验,验证了该机器人的壁面自适应和舱内行走的能力。 相似文献

Development of a Tracked Climbing Robot 总被引:6,自引:0,他引:6
This paper describes a climbing robot, using chain-track as the locomotive mechanism and suction cups as the adhesion method. The main structure, sensors, and the vision-based motion control system of the robot are described in the paper. The robot can turn in a limited range by adjusting the steering wheel and twisting the chain. The turning gait is discussed and relations between turning angles of the chain node, the front wheel, and the frame of the robot are formulated. Forces applied to the robot are analyzed in order to obtain a safety condition that prevents the robot from slipping and falling. An experiment is conducted to measure the safety factor of suction cups and determine the payload capacity of the robot. 相似文献

Abstract: The motion control problem for the finger of a humanoid robot hand is investigated. First, the index finger of the human hand is dynamically modelled as a kinematic chain of cylindrical links. During construction of the model, special attention is given to determining bone dimensions and masses that are similar to the real human hand. After the kinematic and dynamic analysis of the model, in order to ensure that the finger model tracks its desired trajectory during a closing motion, a fuzzy sliding mode controller is applied to the finger model. In this controller, a fuzzy logic algorithm is used in order to tune the control gain of the sliding mode controller; thus, an adaptive controller is obtained. Finally, numerical results, which include a performance comparison of the proposed fuzzy sliding mode controller and a conventional sliding mode controller, are presented. The results demonstrate that the proposed control method can be used to perform the desired motion task for humanoid robot hands efficiently. 相似文献

A new locomotion method for unmanned (autonomous) ground vehicles (UGV) is proposed based around six independently driven wheels mounted on three separate modules. Each module is attached to the overall robot via a pivot point and capable of independently controlling its orientation and velocity. This configuration allows the UGV to perform maneuvers conventional vehicles cannot perform, and in particular to control the body orientation separately from the movement direction. The locomotion method is mathematically analyzed to develop appropriate control algorithms and to demonstrate the vehicle performance criteria. A vehicle was constructed according to the proposed configuration and experimentally tested in the UK Ministry Of Defense grand challenge. The performance of the developed locomotion schemes helped the robot make it to the finale of the competition. 相似文献
