This paper presents a direct formulation of dynamical equations for a space robot actuated by control moment gyros (CMGs). The space robot consists of a service satellite and a robotic manipulator comprising an arbitrary number of rigid links connected by spherical joints. A cluster of CMGs is mounted on the base and on each link. The static and dynamic imbalances of the gimbals and the rotors are both considered. Dynamical equations for the robotic system level are derived using Kane's equations. The nominal output torques of the CMGs and the disturbance torques caused by the imbalances are separated, with each having explicit expressions. A feedback controller based on the nominal model is also proposed for system trajectory tracking control. Simulation comparisons based on different imbalance parameters show that the controller works, but the imbalances may cause both high-frequency and low-frequency disturbance torques, which may distinctly decrease system-control accuracy.

The 3rdinternationalconference on robotics and automation in Industry (ICRAI) is being organized by the National Centre of robotics & automation (NCRA), Department of Mechatronics, NUST College of Electrical and Mechanical Engineering, Rawalpindi. This conference is one of the leading international forums in Pakistan for researchers in robotics and automation to present their work. Previously ICRAI conference was held in the year 2012 and 2016 at NUST College of E&ME. The internationalconference on robotics and automation in Industry aims to bring together leading engineers, scientists, academics, researchers, policymakers, field and application engineers, industries, companies, startups, and scholars to exchange and share their experiences and research results related to robotics and automation industry. It provides a forum for participants to present their latest research goals, design, developments, manufacturing and applications in all areas of robotics and automation in industry. The conference will be a technical gathering of representatives from the eleven research labs of NCRA from different universities of Pakistan. Foreign Keynote speakers and NCRA Scientific and Industrial Advisory Board (SIAB) foreign and local members will also participate in the conference.

A peristaltic continuous mixing conveyor that focuses on the mechanism of the intestine has been developed as a technology for the mixing and transport of a solid-liquid mixture and high viscosity fluids. The developed peristaltic continuous mixing conveyor succeeded in the mixing and transport of such mixtures in a previous study. A simple cyclic pattern is currently used as the movement pattern of the system, and the control method can be further improved. In this study, we aim to realize an intelligent mixing and generation of a conveyor pattern based on intestinal movement. The mixing state of content during activation was estimated through machine learning. The results from the time-series measurement data show that an internal mixing state in three units of the peristaltic continuous mixing conveyor was estimated.
Most industrial robotic manipulators are used for specific type of operation with predefined movements. This is obvious because industrial robots are constructed to perform repetitive tasks with certain precision and ...
