This paper introduces a mobile humanoid robot platform able to execute various services for humans in their everyday environments. For service in more intelligent and varied environments, the control system of a robot must operate efficiently to ensure a coordinated robot system. We enhanced the efficiency of the control system by developing a dual-network control system. The network system consists of two communication protocols: high-speed IEEE 1394, and a highly stable Controller Area Network (CAN). A service framework is also introduced for the coordinated task execution by a humanoid robot. To execute given tasks, various sub-systems of the robot were coordinated effectively by this system. Performance assessments of the presented framework and the proposed control system are experimentally conducted. MAHRU-M, as a platform for a mobile humanoid robot, recognizes the designated object. The object’s pose is calculated by performing model-based object tracking using a particle filter with back projection-based sampling. A unique approach is used to solve the human-like arm inverse kinematics, allowing the control system to generate smooth trajectories for each joint of the humanoid robot. A mean-shift algorithm using bilateral filtering is also used for real-time and robust object tracking. The results of the experiment show that a robot can execute its services efficiently in human workspaces such as an office or a home. 相似文献

In this paper, we describe the development of a quadruped robot named HuboDog. The objective of this project is to develop a reliable and robust quadruped robot platform that enables the implementation of stable and fast static/dynamic walking on even or uneven terrain, and walking while carrying a payload. A lightweight but highly rigid platform is achieved via a frame-type structure and double-supported beam-type joint design. A small, light but high output power joint actuator is designed with a harmonic reduction gear and electric motor that has high speed and a high output power. A distributed control system is used since it can reduce the computational burden of the main computer and easily extend the electrical components. Microprocessor-based subcontrollers are developed for motor control and sensor signal feedback. The main computer, which is mounted on the trunk, communicates with the subcontroller via the CAN (Controller Area Network) protocol. We used Windows XP as the operating system and have established a real-time control system in Windows XP by using RTX (Real Time eXtension) software. This paper includes design concepts, mechanical system design, system integration and electrical system design. In order to demonstrate the performance of the robot platform, simple experiments were performed. 相似文献

CMAC在仿人机器人逆运动学计算中的应用 总被引:2,自引:1,他引:2
本文采用关节角位移和末端位姿误差作为小脑模型神经网络(CMAC)的输入,根据仿人机器人的正运动学模型来调整CMAC的权值,使网络最终逼近仿人机器人的逆模型,从而得到末端位姿到各个关节角的映射关系,避免了传统解析方法面临的计算量大、解不唯一的问题。MATLAB仿真结果表明,利用CMAC对仿人机器人的逆运动学问题求解,可以保证机器人位姿较好地跟踪给定的参考轨迹,说明CMAC能够逼近仿人机器人的逆运动学模型。 相似文献
