In this research, we consider modeling of violin playing robot arm. MATLAB/SIMULINK are used for modeling of robot arm with seven degrees of freedom is considered, which is flexible than previously used robot arms with 6 joint for violin playing. Also, previous robot system which used Mitsubishi industrial robot arm (RV-2SD) is updated. In this model, torque, current consumption and voltage of each joint can be measured. Dynamixel-Pro from robotis Co., Ltd. is used for the joints. This robot arm with seven joint has same range of movement (RoM) with human. This makes our designed robot good at violin playing. This paper presents basic violin playing technique, 3D modeling using Solidworks software, PID control system of servo motor using MATLAB/SimMechanics tool, and physical system of servo motor.

This paper presents the compliance modeling and error compensation for an industrial robot in the application of ship hull welding. The Cartesian stiffness matrix is derived using the virtual-spring approach, which takes the actuation and structural stiffness, arm gravity and external loads into account. Based on the developed stiffness model, a method to compensate the compliance error is introduced, being illustrated with an industrial robot along a welding trajectory. The results show that this compensation method can effectively improve the robot's operational accuracy, allowing the actual trajectory of the robot with auxiliary loads to coincide with the target one approximately.

In the past decade, there have been a lot of researches on various models and controllers for two-wheeled inverted pendulum-type mobile robots. Two-wheeled inverted pendulum-type mobile robots are suitable for the service robots working both in the indoor and outdoor environments. In this paper, a bistable two-wheeled mobile robot which can tilt up and down (B-TMR) is designed and implemented. The B-TMR remedies the weak points of two-wheeled inverted pendulum-type mobile robots. The robot body is designed to maintain balancing state and tilted state. Cost efficiency is improved by using a single accelerometer with a Butterworth filter in order to measure inclined angle. To control five motion modes (Mode 1-Balancing;Mode 2-Tilt Up;Mode 3-Tilt Down;Mode 4-Tilted Move;Mode 5 - Balancing Move), a mode-selective controller is proposed. Through various experiments, the proposed hardware and controller are validated.

Human-robot interaction (HRI) becomes one of the new technology coming into people's sight in recent years. A natural way to interact with robots is crucial in creating more intelligent robots. This paper shows a novel way to control and communicate with robots by monitoring live video captured from camera and doing voice interaction on web. Control commands from web are sent to control robots via robot Operating System (ROS). The HRI process relies totally on web, users can interact with robots as long as they can connect to the wi-fi shared by robots.

Up to now, industrial robots with an open architecture have been applied to several tasks requiring high skills such as machining, sanding, and polishing. As one of the notable results, the open architecture allows system engineers at user side to design a feedback control system to develop robotic applications. However, porting of an application software into different makers' industrial robots is not easy even though having an open architecture, because the specifications of interface between PC-based controllers and robots are not standardized yet. In this paper, easy transplantation of a robotic application is tried by using ORiN (Open robot/Resource interface for the Network) middleware interface. The application is the trajectory-following controller with vibrational motion used in a machining robot. First, the removability of undesirable cusp marks on a flat surface is examined through machining experiments. Then, portability of the controller into a small-sized educational robot VE026A with ORiN SDK (Software Development Kit) is evaluated on a simulation environment called WINCAPS III. Finally, a 3D printer-like interface is proposed for the machining robot to be controlled based on STL data. The design, implementation, and experimental results are presented.

In this paper, an adaptive tracking control of a directional drilling system subject to state delays and parameter uncertainties is investigated. The Explicit Force, Finitely Sharp, ZeroMass (EFFSZM) system is used to represent a directional drilling system. Invariance and Immersion (I&I) adaptive control approach is used to ensure the EFFSZM system to follow a set of predefined path autonomously. The performance of the proposed approach is compared to the one L-1 adaptive control under the identical condition. To observe and validate the performance of the proposed approach, several simulation scenarios are conducted. The results show that both the controllers are able to stabilize the system in the presence of parameter uncertainties while maintaining the trajectory tracking error minimum.

This paper introduces an approach to solve the task assignment problem for a large number of tasks and robots in an efficient time. This method reduces the size of the state space explored by partitioning the tasks to the number of robotic agents. The proposed method is divided into three stages: first the tasks are partitioned to the number of robots, then robots are being assigned to the clusters optimally, and finally a task assignment algorithm is executed individually at each cluster. Two methods are adopted to solve the task assignment at each cluster, a genetic algorithm and an imitation learning algorithm. To verify the performance of the proposed approach, several numerical simulations are performed. Our empirical evaluation shows that clustering leads to great savings in runtime (up to a factor of 50), while maintaining the quality of the solution.
A Bayesian test has been previously proposed for a multiple hypothesis testing (MHT) problem with a quadratic loss function such that this problem can fit with some real applications where the concurrent hypotheses sh...

Dynamical identification methods for the industrial robot manipulators are widely and successfully applied to obtain a model that is suitable for controller design. In this paper, the dynamical model of robot was obtained by Newton-Euler method and linearized by a particular approach. A novel glowworm swarm optimization algorithm was introduced to estimate the unknown parameters. The algorithm had been coded in the popular Matlab environment and the procedure was tested in a practical case research to identify the dynamical model of a six degree-of-freedom industrial robot. The results of the identification experiment showed the efficiency of the proposed algorithm.
